关于全球气候变暖的原因和影响英语作文
关于全球气候变暖的原因和影响英语作文全文共5篇示例，供读者参考篇1Global Warming Is Really Scary!Have you ever heard of global warming? It's a super big deal that is happening to our planet Earth right now. Global warming means that the temperature all around the world is getting hotter and hotter each year. This might not seem like a huge problem, but trust me, it's really scary and causing lots of crazy changes!What is making the Earth get so hot? Well, there are a few main reasons. One big cause is all the pollution being put into the air by humans. Things like cars, planes, factories, and power plants burn fuels like gasoline and coal which releases gases into the air. These gases get trapped in our atmosphere and act like a warm blanket around the whole planet, making it heat up more and more over time. It's sort of like if you left the oven on at home - your kitchen would just keep getting hotter and hotter!Another major reason for global warming is deforestation. Deforestation means cutting down and getting rid of forests allover the world. Trees are really important because they take in carbon dioxide (one of the gases heating up the Earth) and release oxygen that we need to breathe. With fewer trees, there is more carbon dioxide just hanging around in the air, heating up the planet.So now you know what is causing this crazy warming to happen. But why is global warming something to be so worried about? What's the big deal? Unfortunately, global warming is leading to a ton of negative effects that are making things on Earth really messed up in a lot of ways.One of the biggest problems is that global warming is causing major climate changes. The weather patterns that have been normal for a long time are getting all mixed up and extreme. There are way more intense hurricanes, wildfires, droughts, heatwaves, and other crazy weather events happening. Just this year there were terrible floods in Pakistan and a super powerful hurricane named Ian that caused huge damage in Florida.Along with weird weather, global warming is also screwing up environments and habitats for animals all over the world. As regions get hotter, the plants and animals that live there can no longer survive like they used to. Their food sources may bedisappearing. The sea levels are rising too which is flooding areas where animals and people live.Another terrible effect of climate change is on the humans living in many parts of the world. In some regions, it is becoming too hot or dry for people to grow food crops properly anymore. People are going hungry or having to leave their homes to find new places to live that are safer. Kids in lots of countries are missing school and having health problems because of heat waves or lack of food and water. It's a really sad situation.And you know what? It gets even worse! The ice caps at the North and South Poles are starting to melt from all the warming. This will lead to more regions getting flooded by rising sea levels in the future. Entire islands or coastal cities may eventually be under water if we don't stop the warming soon! Species of animals like polar bears are at risk of going extinct because their icy habitats are melting away.I don't know about you, but this issue of global warming seems pretty darn scary to me! The good news is that there are things we can all do to help a little bit. We can cut back on wasting energy, recycle more, and our parents can look into driving electric cars that don't make pollution. Every little bit can make a difference.We've gotta take action now before it's too late! I want my kids and grandkids to be able to enjoy nice weather, amazing animals, and a beautiful planet Earth when they are my age someday. Let's all do our part so the Earth doesn't get too hot to handle! The future is in our hands.篇2Global Warming: A Hot Topic for the PlanetHi there! My name is Jamie and I'm going to tell you all about global warming. It's a really important topic that impacts the whole world. Global warming is when the Earth's temperature gets hotter over time. This might not sound too bad, but it's actually a huge problem that is affecting the planet in many ways.What Causes Global Warming?There are a few main reasons why global warming is happening. The biggest cause is something called greenhouse gases. These gases get trapped in the Earth's atmosphere and act like a big, thick blanket. This blanket traps heat from the sun and makes the Earth warmer than it should be.The greenhouse gas that causes the most problems is carbon dioxide (CO2). We produce a lot of CO2 from burningfossil fuels like coal, oil and gas. Fossil fuels give off CO2 when we burn them for energy in power plants, factories, cars and trucks. Cutting down trees is another issue because trees absorb CO2 - so fewer trees means more CO2 stays in the air.There are some other greenhouse gases too, like methane from cows and landfills, and gases used for aerosols and refrigeration. But CO2 is the worst offender when it comes to global warming.How Does It Impact the Planet?Global warming is causing all kinds of crazy changes on Earth. One of the biggest impacts is on the climate and weather patterns. As the planet heats up, we are seeing more extreme weather events like heat waves, droughts, wildfires, floods and intense hurricanes.The warming temperatures are also melting glaciers and sea ice at the north and south poles. All this melting ice is causing sea levels to rise, which could potentially flood low-lying coastal cities and islands over time. Some animal species that rely on ice, like polar bears and penguins, are struggling because their homes and hunting grounds are melting away.Changing climate conditions are also harming agriculture by making it harder to grow crops in certain regions. This not only threatens our food supply, but also the farmers, farm workers and communities that depend on agricultural jobs and businesses.The warming temps and changing rainfall patterns are leading to water shortages in some areas too. This is bad news for people, animals and plants that need fresh water to survive. Droughts can kill crops, spark wildfires, and lead to humanitarian crises.Many ecosystems, habitats and species are being impacted as global warming alters the delicate balance of nature. Scientists are seeing animals and plants needing to migrate to cooler areas to survive. Coral reefs are being bleached and destroyed. Insects that spread diseases are expanding their ranges. The effects just seem to keep piling up!What Can We Do About It?Tackling global warming won't be easy, but we have to try for the sake of the planet. The main solution is to reduce our greenhouse gas emissions by using cleaner energy sources and being smarter about energy. Instead of burning so many fossil fuels, we need to shift towards renewable energy like solar, windand water power. We can drive more efficient cars, insulate our homes, and turn off lights when not needed.Planting more trees and forests is helpful because living trees absorb CO2. Developing better farming practices and managing water wisely are important too. On an individual level, we can take small steps like walking or biking instead of driving, recycling, and using less single-use plastics.Scientists, governments and ordinary citizens all need to work together on solutions. New technologies and policies are required to lower emissions and transform how we produce and consume energy. It's a huge challenge, but we must take action soon to protect the planet for our generation and those to come.I hope this has helped explain what global warming is, why it's a major problem, and what can possibly be done about it. The future health of the planet is kind of a hot topic and will affect kids like me as we grow up. We can be part of the solution by learning about the issue and making environmentally-friendly choices. Taking care of Mother Earth has to be a team effort!篇3The Big Problem of Global WarmingDid you know that our planet Earth is getting hotter and hotter? It's true! The temperature all over the world is going up little by little each year. This is called global warming, and it's a really big deal.Global warming means the whole globe is warming up. The globe means the planet Earth. You can think of it like putting a jumper on and getting too hot and sweaty! Except it's happening to the entire Earth instead of just you.What's Causing the Warming?So what's making the Earth get so toasty? Well, there are a few main reasons.One biggie is pollution from cars, factories, and power plants. They burn coal and oil which releases gases into the air. These gases are called greenhouse gases. Greenhouse gases trap heat from the sun inside the Earth's atmosphere, kind of like a nice warm greenhouse!Another reason is that we're cutting down too many trees and forests. Trees are really good at absorbing the greenhouse gases and turning them into oxygen for us to breathe. But when we chop them all down, those gases just build up in the air instead.There are some other causes too, like the Earth's orbit around the sun changing over many years. But the human causes of pollution and deforestation are the biggest problems we need to try and fix.Uh-Oh, That Sounds Bad!You're right, global warming is a huge problem! It's causing all kinds of crazy effects around the world. Let me tell you about some of them:• The polar ice caps are melting, which puts cities and islands near the ocean at risk of flooding as sea levels rise higher and higher.• Extr eme weather is becoming more common, like terrible hurricanes, droughts where no rain falls at all, wildfires that spread quickly, and powerful heatwaves.• Animals are losing their homes and food sources as temperatures change in the places they live. Some are even going extinct because they can't adapt fast enough.• People's health is also affected, with more heat strokes, diseases spreading to new areas, and problems growing enough food to feed everyone.Those are just some of the effects, and they're only going to get worse unless we do something about it really soon!What Can We Do?Don't worry though, there is hope! If we all work together, we can help stop global warming from getting out of control. Here are some things we can do:• Drive less, walk/bike more, and take public transportation to reduce pollution from cars.• Turn off lights and electronics when you aren't using them so you don't waste electricity from power plants.• Reduce, reuse, and recycle as much as possible to cut down on energy used to make new products.• Plant more trees and don't cut down forests unless completely necessary. Trees are our friends!• Support leaders who care about protecting the environment and dealing with climate change.If everyone does their part, we can get this global warming thing under control before it's too late. We only have one amazing planet Earth, so we need to take really good care of it.After all, we live here! Let's make sure the Earth stays cool (but not too cool!) for a super long time.篇4Global Warming: A Big Problem for Our PlanetDo you ever feel really hot and sweaty on a sunny day? Well, planet Earth is feeling that way too, and it's because of something called global warming. Global warming is when the Earth's temperature rises, and it's a huge problem that's affecting the whole world.What's Causing Global Warming?There are a few main reasons why the Earth is getting warmer. The biggest cause is something called greenhouse gases. These gases trap heat from the sun inside the Earth's atmosphere, kind of like a greenhouse traps heat inside to help plants grow. The more greenhouse gases there are, the hotter the Earth gets.One of the main greenhouse gases is carbon dioxide, which comes from burning fossil fuels like coal, oil, and natural gas. We burn these fuels to power our cars, factories, and power plants that make electricity for our homes. Another greenhouse gas ismethane, which comes from things like cows burping and farts (yes, really!), as well as from landfills and natural gas production.Deforestation is also contributing to global warming. Trees absorb carbon dioxide from the air, but when we cut them down, there are fewer trees to do this job. Plus, when the trees are burned or left to rot, they release even more carbon dioxide into the air.So, in short, the main causes of global warming are: burning fossil fuels, raising livestock (like cows), deforestation, and other human activities that release greenhouse gases into the atmosphere.What's Happening Because of Global Warming?Global warming is causing some pretty scary changes to our planet. Here are a few of the biggest impacts:Rising temperatures: As the Earth gets hotter, we're seeing record-breaking heat waves and more extremely hot days. This can be dangerous for people, animals, and plants.Melting ice and rising sea levels: The heat is causing glaciers and ice sheets in places like Greenland and Antarctica to melt. All that melted ice is flowing into the oceans, making sea levels rise.This can lead to flooding in coastal areas and even entire islands being swallowed up by the ocean!Extreme weather: Global warming is making weather patterns more extreme and unpredictable. We're seeing more intense hurricanes, droughts, floods, and wildfires.Habitat and species loss: As temperatures rise and habitats change, many plants and animals are struggling to survive. Some species are even going extinct because they can't adapt fast enough.Food and water shortages: Extreme weather like droughts and floods can damage crops and make it harder to grow food. Plus, rising sea levels can contaminate freshwater supplies with saltwater.These are just a few examples of how global warming is affecting our planet. It's a really big problem that we all need to work together to solve.What Can We Do About It?Luckily, there are things we can do to help stop global warming from getting even worse. Here are some ideas:Use less energy: We can conserve energy by turning off lights and electronics when we're not using them, and by walking, biking, or taking public transportation instead of driving cars.Switch to renewable energy: Instead of burning fossil fuels like coal and oil, we should use more renewable energy sources like solar power, wind power, and hydropower. These don't release greenhouse gases.Reduce, reuse, recycle: By reducing the amount of stuff we buy and use, reusing things instead of throwing them away, and recycling as much as possible, we can cut down on waste and pollution.Plant trees: Trees absorb carbon dioxide from the air, so planting more trees can help remove some of the greenhouse gases that cause global warming.Spread awareness: We can learn as much as we can about global warming and share that information with our friends, families, and communities. The more people know about the problem, the more we can all work together to find solutions.Global warming is a really big challenge that affects everyone on Earth. But if we all do our part, we can help make adifference and protect our planet for the future. We only have one Earth, so we have to take care of it!篇5Global Warming: A Big Problem for Our PlanetHi, my name is Emily and I'm going to tell you all about the really important topic of global warming. Global warming is something that is happening to the entire Earth, and it's a huge problem that we need to try to stop.What is global warming? It means that the temperature of the Earth is getting hotter over time. The Earth's temperature goes up and down in natural cycles, but in the last 100 years or so, it has been getting a lot hotter than it should be. Scientists can measure this by looking at temperatures over many years from weather stations all around the world.Why is this happening? The main reason is because of something called the "greenhouse effect." The Earth has an atmosphere, which is the layer of gases surrounding the planet. Some gases in the atmosphere, like carbon dioxide and methane, trap heat from the sun. This is a natural thing that helps make the Earth warm enough for humans, animals, and plants to live. But humans have been burning a lot of fossil fuels like coal, oil, andnatural gas. When we burn these fuels, it releases extra carbon dioxide and other greenhouse gases into the atmosphere. This is making the greenhouse effect much stronger than it should be, causing too much of the sun's heat to get trapped.There are some other causes too. Cutting down forests means there are fewer trees to absorb carbon dioxide. Growing populations means more cars, homes, and factories that burn fossil fuels and produce greenhouse gases. All of these human activities are making global warming worse and worse.So what's the big deal about the Earth getting a little hotter? Why is global warming such a huge problem? Well, it's causing all kinds of crazy things to happen to the environment and weather patterns. Here are some of the biggest impacts:Melting Glaciers and Rising Sea LevelsAs the Earth gets hotter, the ice caps and glaciers at the North and South Poles are melting rapidly. All that melting ice is causing sea levels to rise, which could one day flood cities and towns located along coastlines. Islands could disappear completely under the rising seas. Higher sea levels also make storms and hurricanes much more dangerous and destructive.Extreme WeatherGlobal warming is messing up normal weather patterns and causing more frequent and intense extreme weather events.We're seeing more deadly heat waves, droughts, wildfires, flooding, and stronger hurricanes/cyclones. These cause terrible damage to homes, crops, and forests. Many people and animals die or have to leave their homes because of these disasters.Plants and Animals Going ExtinctAs temperatures rise, many plants and animals can't survive in the changing climate. Their habitats and food sources disappear. We could lose many special and unique species forever. This messes up the balance of nature.Food and Water ShortagesWith more droughts and extreme weather, it becomes really hard for farmers to grow crops for us to eat. Rising sea levels will also contaminate sources of drinking water for millions of people. Less food and clean water means starvation and disease for many.Human Health RisksExtreme heat can cause deadly heat strokes, especially for young kids and older people. There are also more diseases likemalaria spreading to new areas as the climate warms. Air pollution from burning fossil fuels is horrible for our lungs too.Those are just some of the scary impacts that global warming is having and will continue to have in the future if we don't stop it. Scientists predict things will just keep getting worse and worse for planet Earth.So what can we do about this major problem? Well, we need to try our best to reduce the greenhouse gas emissions that are causing global warming. We can walk, ride bikes, or take public transportation instead of driving cars. We can conserve energy by turning off lights and unplugging devices when not using them. Recycling, reusing, and reducing waste helps too. Planting more trees is great because they absorb carbon dioxide.Governments and companies also need to make big changes. They should pass laws to limit pollution from factories and vehicles. More renewable energy sources like solar and wind need to be used instead of fossil fuels. Citizens need to demand action on climate change.It might seem hard for kids to make a difference, but every little bit helps. The future of the planet depends on it! We can all do our part to take care of the environment. Our beautiful Earth is the only home we have. We need to protect it from globalwarming and keep it healthy for generations to come. Thanks for reading!。
气候变化相关的雅思英语作文(精选)
气候变化相关的雅思英语作文（精选）Some people think that instead of preventing climate change, we need to find a way to live with it. To what extent do you agree or disagree?If instead of taking the above measures we simply try tolive with climate change, I believe that the consequences will be disastrous. To give just one example, I am not optimisticthat we would be able to cope with even a small rise in sea levels. Millions of people would be displaced by flooding, particularly in countries that do not have the means to safeguard low-lying areas. These people would lose their homes and their jobs, and they would be forced to migrate to nearby cities or perhaps to other countries. The potential for human suffering would be huge, and it is likely that we would see outbreaks of disease and famine, as well as increased homelessness and poverty.In conclusion, it is clear to me that we must address the problem of climate change, and I disagree with those who argue that we can find ways to live with it.参考翻译气候变化对地球的生命构成了重大威胁，但有些人认为，我们需要接受它，而不是试某某某阻止它。

3分钟关于全球变暖的英语演讲稿1In recent years do you think the weather suddenly turned hot had the cool autumn now almost until early October the hottest day in August has reached more than 40 degrees. These is different from normal vision we have ourselves to blame the curse.Today the term global warming has gradually penetrated into our life. The word sounds very academic even feel very far away from us so some people are not. In fact the effects of global warming is beyond our imagination: global precipitation redistribution glaciers and permafrost melt rising sea levels and so on. Both harm the natural ecosystem balance more threatening human food supply and living environment.Now that you have aware of the dangers of global warming you should go to predict and improve it. Imagine if global warming is melting in the 21st century the global average temperature rising gradually so the next super storms the next round of searing heat the next major natural disasters will happen? China? The United States? Japan? No oneknows. The debate has ended. Scientists around the world agree points out that the earths average temperature has increased nearly 1 ℃. Due to all the early warning information human use of thousands of ships tens of thousands of the monitoring stations of the land and outer space satellite to monitor the earth together. Scientists will have the most advanced computer data input model to estimate the earth can face the future. Prediction results are worrying. Forty years later the Himalayan glaciers the water to the survival of millions of people are likely to disappear. The Greenland ice sheet could melt in 50 years. Currently half of the worlds biodiversity in the amazon rainforest but the rainforest is likely to turn into a piece of barren land by the end of the century. Is likely to be the future of the world like in the movie the day after tomorrow tornado ice fracture the temperature fell sharply ice storms freezing rain earthquake flood tsunami volcanic eruption... This is not a crazy fantasy if humans dont stop destroying the environment it will become a reality!However in the warming is also good. Global warming on rice in heilongjiang province has played a large role.Just global warming to human future development is still the do more harm than good.In order to save the planet we should try to be: dont open air conditioning use recycled paper environmental protection to leave themeat with nitrous oxide dont use plastic bags R22 by bus; R22; Little drops of life. Actually its not difficult to environmental protection as long as you support environmental protection is the best gift you gave the planet.Thank you all!3分钟关于全球变暖的英语演讲稿2Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.3分钟关于全球变暖的英语演讲稿3global warming the gradual increase of the temperature of the earths lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.The temperature of the atmosphere near the earths surface is warmed through a natural process called the greenhouse effect. Visibleshortwave light comes from the sun to the earth passing unimpeded through a blanket of thermal or greenhouse gases composed largely of water vapor carbon dioxide methane nitrous oxide and ozone. Infrared radiation reflects off the planets surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward keeping the planet at an average temperature suitable to life about 60°F (16°C).Growth in industry agriculture and transportation since the Industrial Revolution has produced additional quantities of the natural greenhouse gases plus chlorofluorocarbons and other gases augmenting the thermal blanket. It is generally accepted that this increase in the quantity of greenhouse gases is trapping more heat and increasing global temperatures making a process that has been beneficial to life potentially disruptive and harmful. During the past century the atmospheric temperature has risen 1.1°F (0.6°C) and sea level has risen several inches. Some projected longer-term results of global warming include melting of polar ice with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; profound changes in agriculture due to climate change; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases.Improved automobile mileage reforestation projects energyefficiency in construction and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S. production of greenhouse gases. More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels the elimination of chlorofluorocarbons and the slowing of deforestation by restructuring the economies of developing nations. In 20__the Bush administration proposed several voluntary measures for slowing the increase in instead of reducing emissions of greenhouses gases.3分钟关于全球变暖的英语演讲稿4Global WarmingThere is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). The warmest since the mid 1800’s was the 1990s. The hottest years recorded were 1997, 1998, 2021, 2021, 2021.The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end -enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City.So now we know what some of the causes are for global warming,how can we as individuals do our part to help save the planet?The answer is simpler than you may think. You don’t have to go miles away from home to protest, or spend masses of money. If you try to follow the few simple steps that I shall now give you, you will have started to help us all.Firstly, plant a tree. This could be easier than it sounds. Join or help out a local wildlife group and ask to plant a tree. Trees, when fully grown, will help keep the planet cooler. On the same point, you could protest against the demolition of the rainforests. This is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.Something as simple as walking instead of taking the car will help reduce pollution. As well as stopping pollution, you are giving yourself exercise, something important for our bodies. So the next time you get into your car, or your motorbike, think - do I have to make this journey by vehicle or can I walk?When you are at home, and your getting a little cold. Put a jumper on and do not adjust the heating. The extra heat produced by our homes also affects the planet. So try wearing an extra layer in winter.If possible, buy your fruit and vegetables from local suppliers. And try to avoid imported goods. The more foreign food that we import the more pollution from aeroplanes and boats it will create.Keeping to the speed limit can also help the environment. The more you speed the more petrol you are going to use, making the pollution higher. Also, SUV’s make about six times their own weight in CO2 each year. A small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.If possible use solar energy, after all it is free; all you need to buy is the equipment. You can get much of your hot water and heating from the sun and even generate electricity.Reduce, reuse and recycle. Only buy what you need; don’t stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is as simple as that.Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.If everybody stuck to these rules, we would be doing a great thing by protecting the earth. So please take into consideration what I have said, and try to do your part. After all, it will be our next generation that will feel the effects.3分钟关于全球变暖的英语演讲稿5The topic of global warming is attracting the attentions of countries all over the world. This global warming is on such a scale that it will wreak havoc on both poor and rich countries. It could even make largesections of the earth uninhabitable.What have caused global warming? The theory and evidence strongly suggest that human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming.How we should fight global warming? We should be taking active steps now to curb emissions and we should be engaging in international co-operation to do so. A simple natural way to fight global warming is to have escalating Taxes on carbon emissions. There is a simple reason why this is the ideal remedy: carbon emissions into the atmosphere constitute a nuisance to everybody on the planet; so those who make this nuisance should pay for their actions. A further recommendation is that there should be large-scale government support for research into new technology that will reduce carbon emissions.China is the rising economic star; and if it also wants to assert world leadership status, it is a good opportunity for China to show the world that it has a moral commitment and the will to fight global warming.3分钟关于全球变暖的英语演讲稿。
托福阅读真题第22套
第2 2套Economic Decline in Europe during the14th CenturyParagraph1After three hundred years of impressive gains in wealth and population,Europe’s economy began to slow around1300.Several factors accounted for the decline.One of the most important,though perhaps the least dramatic to relate,was a shift in climate.The remarkably fair weather of the twelfth and thirteenth centuries took a decided turn for the worse in the fourteenth Chronicler’s comments,tree-ring examination,and pollen analysis all indicate that over the course of the fourteenth century Europe’s average annual temperature declined approximately two degrees Celsius—which may sound like very little at first,but if one considers current projections about the possible effects of global warming,in which the average annual temperature shift is only one degree Celsius,a rather different impression emerges.As the temperature dropped,shortening the summer growing season and affecting the resilience of certain vegetable species,the wind and rain increased.This meant that crop yields declined precipitously and the agricultural economy began to contract.As food supplies dwindled,costs rose accordingly and cut into the amount of capital that people had available for other purchases or investments.This in turn added to the gradual constriction of the commercial economy.1.The phrase“accounted for”in the passage is closest in meaning toA.predictedB.explainedC.typifiedD.worsened2.Why does the author mention“current projection about the possible effects of global warming”in the passage?A.To argue that global warming was a faction in the climate shift of the fourteenth century in EuropeB.To suggest that the current climate change is greater than the climate change in the fourteenth century in EuropeC.To show the direct connection between temperature changes in the fourteenth century and changes that are currently occurring in EuropeD.To emphasize the impact of the temperature changes that occurred duringthe fourteenth century in Europe.3.In paragraph1,all of the following are mentioned as factors that contributed to thedecline of the agricultural economy in the fourteenth century EXCEPTA.an increase in rain and windB.a shortened growing seasonC.the investment of capital in areas other than agricultureD.a significant drop in temperatureParagraph2Just as significant were changes in the geopolitics of the Mediterranean world.The decline of the Byzantine Empire,which had dominated the eastern Mediterranean, meant the interruption of trade routes to central and eastern Asia.The rise of new political powers signaled a new era in Mediterranean connections,one in which religious loyalty and ethnic fidelity mattered morethan commercial ties.Consequently the movement of goods and services between east and west began to slow.European interest in circumnavigating Africa and exploring westward into the Atlantic Ocean,in fact,originated in the desire into the trade with eastern Asia that had long sustained Europe’s economic growth.4.In paragraph2,the author implies that Byzantine EmpireA.allowed international trade from which Europe benefitedB.became a dominated force during the fourteenth centuryC.centered its rule on religion and ethnic tiesD.interrupted trade routes to Asia that had already been established5.According to paragraph2,European interest in exploring the coast of Africa and the Atlantic Ocean grew out of a wish toA.build a roadblock against Asian powersB.restore valuable trade with eastern AsiaC.create faster trade routes to eastern AsiaD.connect trade between the eastern Mediterranean and the Atlantic OceanParagraph3A more immediate cause of the sputtering economy was an observable absence;since the eleventh century there had been few significant changes in the technology of agriculture.Developments like the wheeled plow,the rotation of crops,and the use of natural fertilizer that had made possible the agricultural revolution of the past two hundred years had had no follow-up.Farming was still conducted in1300roughly the same way it had been done in1100,but with a considerably larger population to feed, there was little surplus left to generate fresh capital.As a consequence,food production fell perilously close to subsistence level.【Although the failure of agriculture to keep up with the growing population did not become a crisis until the fourteenth century,clear signs of the problem had already emerged by the middle of the thirteenth century,when occasionally low yields due to bad weather or social disruption revealed how perilous the balance between Europe’s population and its food supply had become.】Apart from territories beset by war,the tentativeness of thefood supply became evident first on the farmlands most recently brought under cultivation during the economic depression of the twelfth century.The less established farmers of these lands frequently did not have the means to survive successive poor harvests.Tenant farmers unable to pay their tents thus began to slip into debt,and landlords who depended on rents for their income began to rely increasingly on urban financiers for credit.6.According to paragraph3,what was one cause of the economic problems in Europe of the fourteenth century?A.Farming techniques produced insufficient amounts of foodB.Terntones that farmers had begun to use for agriculture for the first time were disrupted by warC.The technological improvements in farming made in earlier centuries were abandoned after1300D.Farming techniques used capital that was needed for investment in the development of technology7.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?Incorrect choices change the meaning in important ways or leave out essential information【Although the failure of agriculture to keep up with the growing population did not become a crisis until the fourteenth century,clear signs of the problem had already emerged by the middle of the thirteenth century,when occasionally low yields due to bad weather or social disruption revealed how perilous the balance

land recently brought under cultivation were at a bigger disadvantage than well-established farmersin fourteenth-century Europe becauseA．they land was located in areas that were engaged in warB．they relied on urban financiers for creditC．they had no surplus on which to live or money to pay their rentD．they did not use wheeled plows,rotate their crops,or use natural fertilizerParagraph4Even whole governments became entangled in the credit crisis,England being the most notable example.The cycle of indebtedness was hardly inevitable,but the string of bank failures and commercial collapses in the first half of the fourteenth century was striking.The famed Bardi and Peruzzi banks of Florence(the two largest financial houses of Europe)collapsed spectacularly in the1340’s.They were soon followed by the Riccardi bank of Lucca,whose massive loans had kept the English government afloat for years.Many more houses collapsed in turn.10.The word“striking”in the passage is closest in meaning toA.understandableB.necessaryC.limitingD.noteworthy11.Why does the author mention in the passage that the Bardi and Peruzzi banks were “the two largest financial houses of Europe”?A.To indicate the connection between Florence banks and the English governmentB.To emphasize the great impact that these bank failures had on the economyC.To compare the Bardi and Peruzzi banks with the Richard bankD.To indicate the success that these banks had previously achievedParagraph5An important demographic trend resulted from and contributed to the economic malaise:large-scale migration of rural populations into the cities.Europe’s overall population growth from1050to1300had been primarily due to an increase in the number of rural folk.But as economic forces made agrarian life more perilous around 1300,hard-pressed farmers and their families began to migrate to the cities in large number in search of work.Farms,villages,and entire regions were abandoned.Many cities doubled in size,and some even tripled,over the course of just one or two generations.Few were capable of absorbing such large numbers of people.12.Paragraph5suggests that the large-scale migration to cities resulted in which of the following?A.After two generations in the cities,migrants returned to agricultural lifeB.The overall population in Europe declinedC.Farmers worked in cities,and their families worked the landD.Cities contained large numbers of people who were unemployedParagraph5An important demographic trend resulted from and contributed to the economic malaise:large-scale migration of rural populations into the cities.Europe’s overall population growth from1050to1300had been primarily due to an increase in the number of rural folk.[A]But as economic forces made agrarian life more

passage.Farms,villages,and entire regions were abandoned.Where would the sentence best fit?14.Directions:An introductory sentence for a brief summary of the passage is provides plete the summary by selecting the THREE answer choices that express the most important ideas in the passage.Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage.This question is worth2points.The economic decline in Europe during the fourteenth century resulted from several factors.Answer choicesA.Climate changes affected agriculture production,which led to food shortages.B.The loss of trade with central and East Asia negatively impacted economic growth.C.England was among the nations that suffered a credit crisis.D.The performance of the commercial economy could not keep pace with the agricultural economy.E.The lack of innovation in agricultural technology affected food productionF.Migrations from city to rural areas led to an increase in the number of rural fork.Human Impacts on BiogeographyBiologists,who commonly study the distribution of plant and animal species in different environments—their biogeography—strive to develop interpretations or explanations of the patterns of species distribution,but these may be incorrect if the effects of human beings are not taken into consideration.In some cases,these effects may be accidental;for example,some species of rat were unintentionally transported aboard ships from Europe to the islands of the South Pacific.In other cases,species distributions may have been deliberately modified by human beings.The Polynesians in the South Pacific intentionally moved the kumara(sweet potato)to islands in that region to provide the population with a new food crop.1.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?Incorrect choices change the meaning in important ways or leave out essential information.(Biologists,who commonly study the distribution of pi ant and animal species in different environments—their biogeography—strive to develop interpretations or explanations of the patterns of species distribution,but these may be incorrect if the effects of human beings are not taken into consideration.)A.In biogeography it is common to consider and study the effects of plant and animal species as they are distributed within environments where humans live.B.Biologists who study environments in which pi ants and animals are distributed have arrived at interpretations or explanations for how species succeed,but these may not be correct.C.To understand plant and animal distribution patterns correctly,biologists must consider the role of hum an beings in the biogeography of speciesD.It is common for biologists who try to understand the effects of humans on their environments to be incorrect in their explanations of certain distribution patterns of plants and animals.2.In paragraph1，the author makes the point that the relocations of rats and the kumara to new environments differed inA.whether or not humans planned to transfer these species to a new environmentB.how far these species had to be transported to arrive at the new environmentC.how difficult it was for these species to become established in the new environmentD.whether or not these species succeeded in the new environmentThe relocation of species by humans(and more recently the imposition of restrictions on movement by way of national controls and world conventions)has been primarily for economic reasons and for environmental protection.For example,humans introduced Sitka spruce trees into Scotland and England from North America to use them as a timber crop.Similarly the Monterey pine tree was introduced into New Zealand in the nineteenth century from California and has become the most widely used species in the timber production industry in that country.The potato has been carried from its native home in the high Andes of South America,modified and developed into many varieties,and transported around the world because it can be used as a food crop.The plant formerly known as the Chinese gooseberry was relocated from its native China to New Zealand where an industry was established around the renamed kiwifruit.3.The word"formerly"in the passage is closest in meaning tomonlyB.previouslyC.officiallyD.interestingly4.In paragraph2，the author mentions Chinese gooseberries and the Monterey pine in order toA.contrast two plant species transplanted for different reasonsB.demonstrate how two extremely different species adapt to a similar environment in New ZealandC.offer evidence that newly introduced species can have unintended positive effects on the environmentD.provide examples of species moved for economic purposes5.The word"desirable"in the passage is closest in meaning toA.easy to spreadB.quick to establishC.wantedD.practical6.The word"relatively”in the passage is closest in meaning toparativelyB.surprisinglyC.extremelyD.at timesWe have extended the distribution of some species because of certain useful traits that make the species desirable beyond their former known range For example,willows have extensive root systems,can grow relatively quickly,and are now used in several countries worldwide to stabilize river margins as a flood protection measure.The distribution of willows has therefore been influenced considerably by human use in river bank management.7.According to paragraph3.why are willows a species that are now found in different countries worldwide?A.They adapt easily to a variety of environments.B.They have characteristics that make them useful in preserving river banks during floods.C.They have a root system that allows them to reproduce easily and live long.D.They require little care or management from humans.The effects of introduced species can be many and varied and can include effects on the distribution of other species.For example,the North American gray squirrel was introduced into England and has now largely displaced the native red squirrel.The accidental introduction of organisms to new areas may have major pest implications. The South African bronze butterfly,the larva(immature insect forms)of which feed on buds and other parts of geraniums and similar flowers,was accidentally introducedinto the Balearic Islands via imported geraniums.In its native South Africa,the distribution and abundance of the butterfly are affected in part by a native wasp that parasitizes(feeds on)the larvae.In the absence of the parasite wasp on the Balearic Islands off the coast of Spain,the butterfly has now spread to mainland Spain where its rapid spread has been accentuated by trade in garden plants and modem transport. The species has become a major pest due to the lack of a natural predator and is now causing great problems for the horticultural industry in Spain.8.The word"accentuated"in the passage is closest in meaning toA.controlledB.intensifiedC.explainedD.restricted9.What can be inferred from paragraph4about geraniums in South Africa as compared to geraniums in Spain and the Balearic Islands?A.The structural parts and buds of geraniums in South Africa differ from those of geraniums in Spain and the Balearic Islands.pared to the geraniums in Spain,the ones in South Africa are less likely to have bronze butterfly larvae as a pestC.Geraniums are less important to the horticulture industry in South Africa than they are to the horticultural industries tries of Spain and the Balearic Islands.D.Geraniums in South Africa ire traded more than the geraniums in Spain and the Balearic Islands are.10.According to paragraph4,why did the South African bronze butterfly become a major pest in Spain?A.Spain has a greater number of flowers for the butterflies to feed onB.The butterfly's larvae reach maturity more quickly in Spain than they do elsewhere.C.There are no natural predators of bronze butterfly larvae in SpainD.The species of geranium that is found in Spain is a more delicate garden plant and easier for pests to consume11.Paragraph4supports which of the following statement about the South African bronze butterfly?A.It was deliberately introduced into two new environments at the same timeB.Its spread on mainland Spain had a significant economic impactC.It changed its parasitizing behavior when it adapted to new environmentsD.Its presence on mainland Spain and the Balearic Islands caused other insect populations to increaseHuman-driven changes in the distribution of some species may result in hybridization (interbreeding)with other species and so have a genetic effect.For example,the North American cord grass was accidentally introduced to the south coast of England in theearly nineteenth century.It hybridized with the European cord grass and resulted in the production of a new species,which in this case is also a major pest plant of estuaries in England where it became dominant and extensive.Information about a species distribution(prior to human modification)maybe applied in pest control programs for the introduced species.Studies of the species in its native habitat may yield information about the factors that limit or influence its distribution and population dynamics.That information may then be applied in the development of strategies to contain and control the spread of pest species.For example, information about the role of the parasitic wasp in the ecology of the bronze butterfly may be utilized in the process of finding control strategies for that species on mainland Spain.12.Paragraph6returns to a discussion of the bronze buttery in order toA.demonstrate that information about species in their native habitat can be applied to controlling their spread in new habitatsB.emphasize the negative effects of parastic wasps on butterflies in generalC.further support the claim that the bronze butterfly was accidentally introduced to mainland SpainD.conclude by recommending the development of careful pest control strategies so that the ecology is not damaged13.Look at the four squares[■]that indicate where the following sentence could be added to the passage.Its presence there helps control the bronze butterfly population.Where would the sentence best fit?Click on a square[■]to add the sentence to the passage.The effects of introduced species can be many and varied and can include effects on the distribution of other species.For example,the North American gray squirrel was introduced into England and has now largely displaced the native red squirrel.The accidental introduction of organisms to new areas may have major pest implications.■The South African bronze butterfly,the larva(immature insect forms)of which feed on buds and other parts of geraniums and similar flowers,was accidentally introduced into the Balearic Islands via imported geraniums.■In its native South Africa,the distribution and abundance of the butterfly are affected in part by a native wasp that parasitizes(feeds on)the larvae.■In the absence of the parasite wasp on the Balearic Islands off the coast of Spain,the butterfly has now spread to mainland Spain where its rapid spread has been accentuated by trade in garden plants and modem transport.■The species has become a major pest due to the lack of a natural predator and is now causing great problems for the horticultural industry in Spain.14.A variety of factors,including human activity,can affect the distribution of species:Answer Choices1.Research has shown that the biogeography of species can change even without human interference as can be seen In the wide distribution of willows along a wide range of river banks.2.Introducing a species to a new environment can have unintended consequences such as those that occurred when a butterfly was relocated to an environment that lacked its natural predator.3.The success of relocating two species together depends on how they help each other survive in a new environment as demonstrated by the South African bronze butterfly and geraniums.4.The study of the relocations of certain species to new habitats has been difficult because it is not always clear if the relocations were natural or caused by humans.5.Humans have relocated species for a variety of reasons,including obtaining new food sources,creating new industries,and taking advantage of the characteristics of certain species6.Understanding the distribution of a species in its native habitat can be useful in controlling Its spread as a pest in Its new habitat.Economic Decline in Europe during the14th Century答案：B D C A B;A B A C D;B D B(ABE)Human Impacts on BiogeographyHuman Impacts on Biogeography答案：C A B D C;A B B B C;B

Global Warming Solutions>Global Warming Solutions Essay:The upsurge in the Earth’s atmosphere’s average temperature is generally because of the greenhouse effect caused by the increased level of harmful gases like carbon dioxide, chlorofluorocarbons, and other gaseous pollutants is global warming.The adverse effects of global warming, starting from the melting of polar ice caps to causing drastic climatic changes, can cost life on Earth.Therefore, it is necessary to come up with solutions to reduce global warming.Long and Short Essays on Global Warming Solutions for Students and Kids in EnglishWe provide students with essay samples of long global warming solutions essays of 500 words and short essay of 150 words on the same topic for reference.Long Essay on Global Warming Solutions 500 Words in EnglishLong Essay on Global Warming Solutions is usually given to classes 7, 8, 9, and 10.Global warming is an alarming cause of the gradual increase in the temperature of Earth’s atmosphere that needs to be controlled immediately. Rising pollution aided by several factors like deforestation, industrialization, and more has severely contributed to this phenomenon. The gases mainly responsible for global warming are carbon dioxide, CFCs, ozone, Sulphur oxides etc. Global warming is not only affecting the climate of Earth adversely but is also responsible for ozone layer depletion.To control global warming, at first, we need to stop deforestation and promote afforestation. Planting trees to several tropical rain forests around the globe and at the same time protecting the already existing tropical rain forests is the first step towards cooling Earth. This is the most cost-effective way to prevent global warming and needs to be immediately tended to.Minimizing the burning of coal and petroleum and controlling the release of harmful gases will significantly impact global warming. We should opt for environment-friendly alternatives such ascompressed natural gas (CNG) instead of petroleum. Industrial coal emissions should be stopped or minimized to cut down the supply of the increasing harmful gases that contribute to global warming. Thus, improvements to energy efficiency and vehicle fuel economy are impactful solutions to global warming.An increase in wind and solar power is a handy alternative to high electricity consumption. Electricity is one of the biggest causes of greenhouse gases emission that significantly contributes to global warming. Lowering electricity consumption can also be achieved bymonitoring the thermostat, improving insulation, and improving airtightness in our homes. Developing and deploying new low-carbon and zero-carbon technologies will cause a reduction in global emissions. Current researches on battery technologies and ways of harnessing energy from natural sources like bacteria and algae can emerge to be very impactful. Renewable energy sources like bioenergy, wind, solar, and geothermal energy lying around us have the potential to meet the rising call for energy without harming the environment. Renewable technologies can be developed andused to make energy usage cost-effective and reduce air pollution.A thriving global compact on climate change must include financial assistance from economically developed countries to the under-developed countries to transition to low-carbon development pathways and adapt to the impacts of climate change and global warming, thus ensuring sustainable development.It is vital to advocate for a healthy planet and educate people on global warming causes and effects. The primary steps for such an advocation would be to limit the number ofcarbon companies allowed to emit, provide resources to prevent emissions and leaks from industrial equipment, and subsidize efficient industrial technologies. Lastly, individuals need to act more sustainably. Every individual has their contribution to making in reducing global warming. The wise use of transportation, conservation of electricity at home, planting trees and plants at home or nearby gardens are some of the fundamental steps that should be taken by all to control global warming immediately and to save Earth and life on it.Short Essay on Global Warming Solutions 150 Words in EnglishShort Essay on Global Warming Solutions is usually given to classes 1, 2, 3, 4, 5, and 6.Global warming is a rising concern for life on Earth. The gradual increase in Earth’s temperature has several adverse effects on our planet and is lethal for all living organisms. Hence, it is necessary to find solutions to global warming. Firstly, we need to abandon coal and petroleum and encourage promoting renewable sources like windmill, solar energy, geothermal energy, and bioenergy. It is the primary step tominimize global warming. Planting more trees and plants naturally filters the air and removes toxic gases. The deployment of zero-carbon technologies is an excellent advancement to reduce global warming.Educating people about the adverse effects of global warming and advocating for solutions to decrease global warming is a fundamental solution that can need to be implemented with urgency. It is wise to take measures before the situation gets out of hand because the rate at which Earth’s temperature increases is alarming and concerning.10 Lines on Global Warming Solutions in EnglishGlobal warming causes various kinds of climate changes like floods, blizzards, disruption in weather patterns, and is the prime cause of ozone layer depletion and needs to be minimized on an urgent basis.Preventing deforestation and execution of more plantation programs are an effective solution to global warming.It is vital to educate every individual about global warming adversities and suggest them the solutions they can work on.All need to minimize the use of electricity and opting for an alternative renewable source of energy.We should prevent the burning of coal and petroleum.Check the release of toxic gases from factories.Donation to environmental charities that work to minimize pollution and global warmings should be made.All should try and purchase ethical products which are carbon neutral and environmentally friendly.Aerosols and pesticides that contain CFCs should not be used.It is necessary to implement global warming solutions immediately.FAQ’s on Global Warming Solutions EssayQuestion 1.What is Global warming?Answer:The elevation of the temperature of the Earth’s atmosphere due to the accumulation of greenhouse gases and other harmful pollutants in the atmosphere is global warming.Question 2.Why do we need solutions for global warming?Answer:Global warming causes melting of polar ice caps, increased water level of oceans and drastic climatic changes that will be lethal to all living organisms. It is also responsible for ozone layer depletion.Question 3.What are the solutions that we can accomplish independently to decrease global warming?Answer:Planting trees, using alternatives for transportations, control on electricityconsumption and using zero-carbon essentials are some ways in which every individual can contribute to decreasing global warming.Question 4.By what percentage does ozone affect global warming?Answer:Stratospheric ozone has 11% effect on global warming.。

英语四级作文全球变暖篇1Environmental ProtectionNo one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way.There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .英语四级作文全球变暖篇2People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experiencedsnowfree(无雪的) winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer daysg.The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.英语四级作文全球变暖篇3With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike. So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.英语四级作文全球变暖篇4With the development of economy, more and more greenhouse gases are being discharged into the air.

Do it right now.英语四级作文全球变暖篇8In this report, I learned a lot of things, but my first thoughtis that the cause of global warming is carbon dioxide increases.Why is carbon dioxide will increase? I think the reason is that people often feed drive, raising livestock, factories discharge smoke... And so on. But these are all can be solved together, perhaps can improve the earth continued warming, for example: close to the destination can ride a bike, Destination is far away, you can use public transport; Livestock waste processed into Hanoi again; Factory can build a waste treatment plant... And so on.Please do not underestimate the power of carbon dioxide, wait until the sea level rise, urban flooding and flooded farmland, in the end would have faced the crisis of insufficient food. Please join me shout: "stop hurt the behavior of the earth! The earth on which we live is only one."英语四级作文全球变暖篇9The cold winter has passed, but this winter with snow is not, is not how cold the weather, why is this so?I asked my mother, my mother said: "I don't know, you go online to check." I opened the computer, input -- global warming. There have been many answers on the layout.Because of human destruction of forests and other greenhouse gases from the burning of when, because these greenhouse gases with high transmittance in the visible light radiation from the sun, and the earth is reflected is highly absorbent, can strongly absorb infrared radiation on the ground, the greenhouse effect is often said that the "". Global warming may lead to consequences, will lead to a global redistribution of precipitation, melting glaciers and permafrost, rising sea levels, damage the balance of the ecosystem and the human food supply and living environment.Global warming is not onlyharmful to humans, but also endanger the survival of animals. For example, the polar bear, because of global warming, melting glaciers and polar bear hunting fish more difficult, and the ice melting fast, this continues, sooner or later the polar bears extinct species like the polar bear, Arctic wolf, Arctic animals are penguins.Want to stop global warming, we should save every drop of water; plant more trees to reduce desertification; do not use disposable convenient bag; reduce the emission of carbon dioxide. I appeal to our homes, we act together now!英语四级作文全球变暖篇10Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.What should governments do to help prevent global warming? Give reasons for your suggestions.The earth’s temp erature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects ofgreenhouse gas emissions and possible solutions to the problem.Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.英语四级作文全球变暖篇11When global warming, the world have changed dramatically.The Antarctic ice and snow melt, human feeling will be under water, it is human to take the consequences. Arctic overlord, the polar bear also gradually extinction due to global warming. Has been the mother to a pair of scissors to bear, baby bear curiously ask: "mother, with scissors stem what ah?" Mom replied in a tone of command: "quick shearing, longer so thick hair will be hot dead!" Naive to bear looked at his mom, "we live in the ice and snow, how can heat? This is our coat, without it will be cold, can't cut!" Mother bear tone with a sad and sigh: "global warming, in does not adapt, now I'm afraid go!"Global warming, the polar bear can't find food, even little bear, it is be compelled helpless! Humans shall make profound reflection to your behavior, but, when global warming, human couldn't realize his mistake! Only know no longer suffer from the cold in winter, the temperature rose, the cold has gone, only the immediate interests, didn't know that will be far away from the white snow, originally should be open the flowers in the winter.When global warming, I hope this to human consciousness already consequences. Early up, to stop all this happen!英语四级作文全球变暖篇12As is subtly revealed in the cartoons above, global warming is a real threat to our world. In the first drawing, the glaciers in the polar region are rapidly melting owing to global warming. In the second picture, a homeless polar bear is staying on an isolated big block of ice.The purpose of these portrayals is to show us that global warming is a looming threat to people all over the world. To begin with, global warming leads to the rise of sea levels. Large sections Chinese coastal regions would gradually disappear under rising sea levels because of global warming, severely impairing the country’s social and economic progress. China’s long coastline is the base for about 70% of the large cities, over half of the domestic population and nearly 60% of the national economy. With comparatively-advanced social, economic and cultural developments, China’s off-shore regions will suffer great losses if the sea level does not cease rising. In addition, global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms. Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years. These upswings correlate with a rise in sea surfacetemperatures due to global warming.Taking into account the devastating effects of global warming, we can draw the conclusion that global warming is a great threat to our world. Facing the growing menace of global warming, more scientific and active preventive measures should be taken on a larger scale to change for the better.英语四级作文全球变暖篇13With the development of economy,more and more greenhouse gases are being discharged into the air.CO makes up about 70% of the greenhouse gases,which is considered to be one of the largest causes of global warming.It has harmful effects,causing the sea level to rise and many natural disasters happening like droughts,severe storms and hurricanes.The side effects of global warming are alarming,so we must take effective mea-sures to save our planet.First,we should use more clean energy and less coal and oil.Second,we should go to work on foot or by bus instead of driving a car if possible.Third,we should plant more trees to turn CO into oxygen.More importantly,we should T omm the habit of saving energy in our daily life.Global warming catches our concem.Only in these ways,can we protect our planet.英语四级作文全球变暖篇14I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.First of all, global warming is one example, soak in the hotweather in summer air conditioning becomes a new "hobby", but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust serious affect our nong cough, throat inflammation... . According to concerning sectional statistic China's per capita emissions of carbon dioxide emissions every year 2. 51 tons a year! The changes in the harsh environment around us.More important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs "of the south-north water diversion project".In order to save the planet, people all over the world should be: don't open air conditioning, use recycled environmental protection bags, don't use plastic bags, take the bus, don't throw waste batteries... Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!下载全文。

Brian Cowles is the producer of a new series of documentaries called "The Earth at Risk" which can be seen on Channel 4 later this month. Each program deals with a different continent, doesn't it, Brian?
For example, in Brazil in 1982 an area of jungle the size of Britain and France combined was destroyed to make way for an iron ore mine. Huge numbers of trees are being cut down for export as hardwood to Japan, Europe, USA to make things like luxury furniture. These forests can't be replaced -- the forest soil is thin and unproductive and in just a few years, a jungle has become a waste land. Tropical forests contain rare plants (which we can use for medicines, for example) and animals -- one animal or plant species becomes extinct every half hour. These forest trees also have worldwide effects. You know, they convert carbon dioxide into oxygen. The consequence of destroying forests is not only that the climate of that region changes (because there is less rainfall) but this change affects the whole world. I mean, over half the world's rain forest has been cut down this century.
全球变暖的原因和影响Causes and Effects of Global Warming英语作文
Causes and Effects of GlobalWarmingThe emissions of greenhouse gases have caused global warming. One of the many effects of global warming is that it has led to an increase in the planet’s temperatures.The leading cause of global warming is the release of harmful and toxic gases into the atmosphere. Some of the harmful gases include carbon dioxide and sulphur dioxide. These two gases are the main ones because of the burning of fossil fuels and industrial activities.There are various effects of global warming. Some of the results are acid rain, climate change and depletion of flora and fauna. Here in this article, we have provided short and long essays on Causes and Effects of Global Warming Essay in English. The essays have been written in simple yet effective English for your information and knowledge and aim to help during school assignments or a speech on Causes and Effects of Global Warming.Short Essay on Causes and Effects of Global Warming 250 Words in EnglishGlobal warming is one of the biggest concerns of people all around the world. One of the most important reasons is a concern because of the rising temperatures of the atmosphere every day.There are many reasons for the increasing temperature of the planet. One of the biggest reasons for global warming is the emission of harmful greenhouse gases in the atmosphere. Some greenhouse gases are carbon dioxide, nitrous oxide, chlorofluorocarbons, and methane.There has been continuous emission of the greenhouse gases by the activity of the humans. Some of the humans’ activities that cause globalwarming are increasing automobiles, industrial activities and burning of fossil fuels. All the activities emit carbon dioxide in the air, which increases the temperature of the planet. The effects of global warming are visible in the environment around us. It is causing glaciers to melt, temperatures to rise, climate changes and unpredictable natural disasters.The increase in environmental temperature and climate change on the planet has become evident in the last five decades. The concentration of the greenhouse gases in the atmosphere of the earth has increased.Gases like water vapour, carbon dioxide, methane, ozone, sulphur and nitrogen contribute to the greenhouse effect increase. People should come together and work toward solving the problem of global warming. The most significant cause of increasing greenhouse gases in the planet’s atmosphere is the burning of fossil fuels. These fossil fuels emit carbon dioxide in the environment, which leads to an increase in greenhouse gases. The greenhouse gases can absorb more heat from various sources and warm the temperature of the planet. The effects that the greenhouse gases have on the environment is called the greenhouse effect.When the environment starts to heat, it leads to changes in the atmospheric temperature and the changes in the sea level. Some of the changes in the atmosphere because of the greenhouse gases are melting of glaciers, soil erosion, famine, natural disasters, and the increase in the annual power of hurricanes. The changes in the environment that are affecting the lives of all the living creatures on the planet.Scientists and economists around the world are trying to find ways to reserve the changes of global warming. Many international organisations are trying to find ways to solve theproblem of worldwide warming and the effect that it is having on the environment.One such organisation working towards researching global warming is the Intergovernmental Panel on Climate Change (IPCC), an organisation under the United Nations. It is an organisation working towards studying the causes, effects and effects to practical solutions.Long Essay on Causes and Effects of Global Warming 800 Words in EnglishGlobal warming is increasing every year because of the continuous emission of greenhouse gases. They trap heat from various sources like the sun, electricity, burning fossil fuels, and stop them from escaping back into the atmosphere. The collection of the greenhouses gases leads to the increase or rise in the temperature on earth. The increasing weather on the planet has caused many problems on earth.Earlier, the planet was cool, and the natural cycles in the climate were going correctly. However, the constant change in theenvironment due to global warming has caused the natural process to become irregular, and it keeps fluctuating. There are fluctuations in the weather, temperature, health and climate.The rising temperature leads to the melting of the ice glaciers. When the glaciers melt, they increase the sea level drastically. In the past few decades, there has been an increase in temperature, sea level and the weather patterns. The various climatic changes happening around us are because of global warming. These effects of global warming are not coincidences. They are happening because of the activities ofhumans and the technological advancement of humans.When there is a little increase in the amount of carbon dioxide emitted in the atmosphere, it causes a massive global temperature change. The continuous rise in the percentage of atmospheric carbon dioxide is dangerous and alarming because it is causing many changes.Many people are ignoring the changes in the environment. People continuously use more fossil fuels for their needs, and this is causing changes in the background. Due to the continuous burning of fossil fuels, the carbondioxide emission in the air is increasing. This is leading to an increase in the temperature of the planet.Another cause of global warming is deforestation. It is causing the depletion of the plants, and it exposes the soil to direct sunlight. One of the best sources that absorb carbon dioxide is trees. However, due to the cutting of trees all around the planet, this source is depleting.Humans cut trees to make more space for human occupation in areas that should be forests. We deplete the green cover and areharming the environment. If there is a little increase in the level of greenhouses gases may impact global warming immensely.One of the major causes of global warming is the use of a chemical called chlorofluorocarbons. You will find the use of chlorofluorocarbons in refrigerators, and aerosols spray propellants and many other objects around you. These chlorofluorocarbons continuously damage the ozone layer, which increases the chance of the heat to remain on the planet. It is preventing the heat from escaping, which is increasing the temperature of the earth.The destruction of the ozone layer is due to the emission of chlorofluorocarbons. When the ozone layer starts depleting, it causes the change in the environments. It causes an increase in health disorders such as skin cancer, respiratory diseases, and respiratory problems.A significant effect of global warming is the damage it does to the seasonal crops and marine food. Marine life is facing the consequences of the changes in the climate as the sea is heating up. The weather changes are drastic due to global warming. Summers are longer, and winters have shortened due toglobal warming. Many countries have banned the use of chlorofluorocarbons because of the effects that it has on the environment. Their ability to degrade the ozone layer and trap more heat than carbon dioxide is the main reason for the ban.There are many other causes of global warming. One of the causes of global warming is the emission of carbon dioxide by cars and other vehicles. The amount of carbon dioxide that is emitted by cars causes serious harm to the environment. In all the countries around the world, there has been an increase in the numberof vehicles on the road. However, there has been a change because of the introduction of electric cars.An effect of global warming is the significant fluctuations in the weather change. There is going to be an extreme change in the weather because of global warming. It is leading to permanent changes in the climate. Another effect of global warming is ice melting. Global warming is causing the ice in the two poles of the planet to melt.The scientists are continuously working towards finding ways to reduce greenhouse gasemissions and save the environment. Climate change and global warming are one of the things that most countries are trying to reverse. The increase in the emission of greenhouse gases is causing many problems in the environment.。
effect of global warming
As climate change becomes extreme, the whole world gets some dangerous extreme events. However, now, global warming's effect not only appears in a high frequency of storms, quick melting of glacier, crop failure and rising sea, but also appears in human health. The disease today especially caused by mosquito increases more and becomes an epidemic disease.In Africa, malaria, which is a disease caused by mosquito, is highly increased. It is caused by the temperature change of African's land into the colder land, so mosquitoes did not move up to the mountain. This condition makes several places like Nairobi and Harar become a place to avoid mosquitoes because they are up in the mountain.After malaria, there is another disease caused by climate change. The rising of sea levels not only causing human physical health becomes weaker, but also causes psychological aberration. It is possible because climate change can affect people to become stressful.Stress is not always looking bad but the condition can lead you to negative act. Stress is obviously negative and recent studies according to scientists stated that theeffect has been faced by citizens in the developing country, especially children. From systematic research in 2000, there were 150,000 premature deaths occur around the world. The global warming effect on human health suspected will occur more in developing countries and 88% affect children. It attacks children who is fragile, malnutrition and those who live in a poor environment and having no access for health services. Lower agricultural productivity in areas where sea levels are rising, make places like Africa, India and the poorest places in Latin America get a malnutrition leads to malaria and vomiting as effects global warming. Climate change will increase water pollution in the open air and directly damage the ozone layer. Ozone layer is very important for human because it is our protection from radiation of sunlight and has a function in temperature. Human failure to keep the earth makes the climate unstable than in past ten years.Know more information about global warming effect to human health, read in global warming causes[].Article Source:/?expert=Jenny_Yolanda_Smith Who is Affected by Global Warming?Humans, animals, plants, climate, land... you name it and it will be affected by global warming. In fact, some species of plants and animals are already on the verge of extinction. Studies indicate that around 15 to 37 percent of plant and animal species will be wiped off the planet by the year 2050. Changes in climatic patterns have already started to show, sea level is rising.... to make it short, we are just heading for destruction.IndexGlobal Warming Effects on the EnvironmentThe average temperature of the planet for each year, over the last decade, has been featuring in top 25 high temperatures of all time. In fact, 1998 and 2005 were the hottest years in the history of the Earth. The planet is getting warmer by the day, and just because the change is happening gradually we can't ignore the fact that we are vulnerable to the threat of global warming. In fact, the appropriate phrase would be - 'the entire planet is threatened by its hazards.Effects on AnimalsA large number of animal species will disappear from the planet, owing to the loss of habitat triggered by global warming. There is no doubt that many animals will bear the brunt of climate change attributed to it. In fact, it's feared that sooner or later it will trigger a mass extinction, and one-third of the animal species will become extinct by 2050.Polar Bears: Polar bears depend on ice formed on thesea when hunting. If the ice melts, the range of polar bear will decrease to a great extent, and this loss of habitat will in turn lead to a decline in the polar bear population.Penguins: Melting sea ice will also result in decline in the growth of algae, which in turn will result in decline of tiny organisms, such as krill shrimp, which constitute a very important part of the penguin diet. And thus, scarcity of food and loss of habitat will eventually drive the penguins towards extinction.Arctic Fox: Warm temperature has been driving the Arctic fox further north in search of cooler habitat, but the rate at which we are losing colder regions, the Arctic fox is bound to lose the battle for survival sometime soon.These were just a few of the animals which are threatened by global warming. The long list includes caribou, butterflies, hibernating animals, migratory birds and various fish species as well.Effects on PlantsOwing to the drastic changes in temperature levels,various plant species have been experiencing difficulties in adapting to the areas wherein once they flourished. The growing season of some plant species has also been altered, which in turn has disturbed the reproduction cycle of the species, thus giving a drastic blow to the plant population. Even the changes in precipitation patterns can lead to hazardous effects on various plants species. Global warming effects on agriculture is the best possible examples of this. Frequent rains will lead to flooding, whereas less rains will result in drought, both of which will only lead to the destruction of agricultural fields.Other natural disasters, such as hurricanes, which are also caused due to global warming, can have a disastrous effects on plant life. Furthermore extinction of animals will also lead to negative impacts on the plant life, either directly or indirectly. For instance, extinction of tiger will result in increase in number of herbivores and excessive feeding by herbivores will result in depletion of the forest cover. Extinction of birds will affect the pollination process and hamper reproductionin plants. Owing to all these factors, various plant species are also expected to become extinct by the end of this century.Effects on WeatherIncreasing temperatures will lead to adverse effects on weather as well. Even minor alterations in global temperatures will trigger a series of weather extremities, and alter the climatic patterns of the planet. The number of natural calamities have increased over the period of time. Last three decades have witnessed a rise in number of category 4 and category 5 storms. The Intergovernmental Panel on Climate Change (IPCC) acknowledges the fact that the frequency of intense rains has increased over the last 50 years. On one hand, heating of the ocean due to global warming gives rise to ferocious hurricanes, while more than the normal temperature on land gives rise to intense heat waves. Higher temperature leads to faster evaporation of water and leads to drought in one part, and brings in heavy rainfalls and causes flooding in other part of the world. Although we can't conclude the serious effects of globalwarming on weather by taking into consideration a single drought year or a single devastating hurricane, the trend of these natural occurrences speak in volumes for themselves.Effects on GlaciersOne of the more severe effects of global warming on Earth is the melting of perennial and permanent ice covers on the planet. There are several thousands of glaciers spread all over the world which form an important source of fresh water. Monitoring of these glaciers, by projects such as Global Land Ice Measurement from Space (GLIMS), has revealed that these glaciers are disappearing at an alarming rate. This is viewed as one of the most prominent factor for rising sea levels. The glaciers at the Patagonian ice fields of Argentina have receded 1.5 kilometers overs the last two decades. The number of glaciers in Glacier National Park in Montana had dropped from an estimated figure of 150 to 50 within a span of 150 years, and is expected to drop further, eventually leading to disappearance of all the glaciers by 2030. Melting glaciers can triggersevere natural calamities, such as flash floods, in the surrounding regions. More importantly, the melted water flows into the oceans thus causing the sea level to rise, which eventually leads to submerging of low lying areas such as Bangladesh and Maldives.Effects on Sea LevelsOne of the most grievous among the various global warming effects on earth is the rise in sea levels, which are threatening to encroach up on land. If the sea levels rise it will result in a watery grave to several low lying areas, tiny islands and reclaimed portions of land. So how exactly is it affecting sea levels? Basics of geographical studies suggests that water expands when heated. In this case, rising global temperatures are causing the water bodies to heat, expand and thus encroach on land. Another prominent reason for sea level rise is melting ice from the glaciers and polar ice sheets - which is again accelerated by global warming. These ice stores are far massive than we can imagine. In fact, melting of West Antarctic Ice Sheet alone can possibly cause the sea to rise by a whopping 10 meters.According to the Intergovernmental Panel on Climate Change (IPCC) the sea levels have seen a rise of 6.7 inches in the last century, and if the alarming rate of global warming continues, the sea water levels may rise up to 22 inches by 2100.This will mean that island like Maldives and Tuvalu and low lying areas like Bangladesh will go underwater, and important cities like Mumbai, Shanghai and Florida will become vulnerable to the water grave like the legendary city of Atlantis. In fact, Maldives islands sinking is the best possible example of destruction due to rise in sea levels.Effects on Coral ReefsThe effects of global warming on the coral reefs are devastating to an extent, that these reefs would the first major ecosystem to be wiped off the planet very soon. When the ocean water gets warm, the algae in the ocean tends to produce toxic oxygen compounds called superoxides which is damaging for the corals. As a defense mechanism, the corals eject their algal lodgers, which leaves the reefs starved for nutrients and theircolor turns white. This process is referred to as bleaching. Global warming is threatening the coral reefs to a great extent, and the fact is that if coral reefs are wiped off the planet, it will affect one third of planets marine biodiversity, as well as other ecosystems related to the coral reefs directly or indirectly.Effects on HumansWhen the whole environment will experience the effects of global warming, naturally humans won't be an exception. In fact, we will be the worst affected beings on the planet because directly or indirectly we are dependent on all the components of the environment discussed above. Animals and plants are related to each other, extinction of either will put tremendous pressure on other, eventually leading to its extinction. Humans, in turn, are dependent on both for many purposes, so extinction of animals or plants will also affect humans to a great extent. Irregular weather will have a severe impact on several human activities. Warmer summers will mean more allergies and even more disease spreading insects. Unnatural precipitation will lead todestruction of crops and hamper agriculture. Rising temperatures will lead to warming of ocean bodies, which will in turn increase the frequency of hurricanes.Destruction of coral reefs will lead to loss of marine life including fish which is an important constituent of human diet. Coastal areas around the world are highly populated, so any rise in sea level will lead to a heavy impact on the people residing in coastal areas. Glaciologist's estimate that if melting of glaciers at the present rate continues, around 20 percent of Bangladesh will get submerged in the sea by 2020. Countries like Maldives, with the highest point of 2.4 meters above mean sea level, will get submerged if the sea water levels rise by 3 meters. Loss of glaciers will hamper the water supply for millions. Rise in sea level will alter the coastlines thus affecting tourism sector. The saline water from oceans will flow into river beds thus making the river water unusable.Effects on EconomyThe repercussions of these effects of global warming onearth will also be felt on the economy of various countries. The most affected would be the countries with agriculture-led economy. The phenomenon will trigger a series of changes in weather conditions which will take a toll on agriculture and allied activities. Owing to unnatural precipitation pattern, crop failure will become a very common phenomenon. Economies dependent on tourism, such as Maldives, will also bear the brunt of global warming. As the water levels rise all the coastal area will get submerged leaving the world devoid of all the beautiful beaches. Considering that the world has become a global village, the domino effect will also be seen on other countries and more importantly on the world economy.Not everything about global warming would be bad though. Warmer climate will mean a longer growing season and hence an increase in production. In the United States, it will melt the polar caps along the Northwest Passage which will lower the shipping costs. The problem is that its negative effects far exceed the positive effects, and thus the whole world is concernedabout the future - and trying to find out some solutions to this problem. The natural causes of global warming which includes water vapor and volcanoes are beyond our reach, but we can make sure that man-made causes are reduced. If we don't initiate the necessary steps soon we will have to face its wrath sometime in near future.Several things have to be taken into consideration before we actually determine global warming effects on our planet. Skeptics argue that most of these problems are being exaggerated. Turning a blind eye to the signs of destruction, they feel that these effects of climate change are not going to take place anytime soon. But then, if a drop of 5 degrees over a considerable period of time can trigger an ice age, won't a rise of 5 degrees have a devastating impact on the planet?By Abhijit Naik1. Toxic Algae May Contaminate More SeafoodBlooms of one kind of "red tide" algae—which create ocean dead zones—may be more frequent as the world warms, especially in North America's Puget Sound region (map), according to Stephanie Moore of NOAA's West Coast Center for Oceans and Human Health.The Alexandrium catenella algae species produces a poison that can accumulate in seafood and subject humans to everything from vomiting to muscle paralysis to, in rare cases, death.1.有毒藻类可能污染更多的海洋食品。
全球变暖的原因和结果英语作文
全球变暖的原因和结果英语作文The Causes and Consequences of Global Warming.Global warming, a phenomenon that has garnered increasing attention in recent decades, refers to the steady rise in the average temperature of the Earth's climate system. This phenomenon is caused primarily by anthropogenic activities, such as the burning of fossil fuels and deforestation, which release greenhouse gasesinto the atmosphere. The consequences of global warming are profound and far-reaching, affecting every aspect of life on Earth.Causes of Global Warming.The primary cause of global warming is the accumulation of greenhouse gases in the atmosphere. Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrogen oxides (NOx), trap heat within the Earth's atmosphere, causing a rise in global temperatures. Human activities arethe primary source of these gases, with the burning of fossil fuels for energy production being the largest contributor. Fossil fuels, including coal, oil, and natural gas, release CO2 when burned, adding to the atmospheric concentration of this greenhouse gas.In addition to fossil fuel emissions, deforestation is another significant source of greenhouse gases. Trees absorb CO2 during photosynthesis, helping to maintain a balance in the atmospheric concentration of this gas. However, when trees are cut down, this CO2 is released back into the atmosphere, contributing to global warming.Other anthropogenic activities, such asindustrialization and urbanization, also contribute to global warming. Industrial processes release large amounts of greenhouse gases, while urban areas generate heat through human activity and the use of energy, causing a phenomenon known as the urban heat island effect.Consequences of Global Warming.The consequences of global warming are numerous and diverse, affecting every aspect of life on Earth. One ofthe most significant impacts is the change in climate patterns, leading to more frequent and severe weather events. This includes extreme heat waves, droughts, floods, and hurricanes, which can have devastating impacts on human life and infrastructure.Another consequence of global warming is the melting of ice caps and glaciers, leading to sea level rise. As ice melts, it adds water to the oceans, causing sea levels to rise. This rise in sea level can have significant impactson coastal cities and island nations, leading to flooding and displacement of populations.Global warming also affects biodiversity and ecosystems. Changes in climate patterns can disrupt the balance of ecosystems, leading to the loss of habitats and species. This can have profound impacts on the food chain and the provision of ecosystem services, such as water purification and carbon sequestration.Additionally, global warming can affect human health. Changes in climate patterns can lead to the spread of diseases and pests, while extreme weather events can cause physical injuries and deaths. The rise in temperature can also contribute to the formation of smog and other air pollutants, which can have adverse effects on respiratory health.Conclusion.Global warming is a complex and far-reaching phenomenon that requires urgent action. The causes of global warming are primarily anthropogenic, with fossil fuel emissions and deforestation being the largest contributors. The consequences of global warming are profound and far-reaching, affecting every aspect of life on Earth. It is crucial that we take action to reduce greenhouse gas emissions and mitigate the impacts of global warming to protect our planet and future generations.。
环境污染导致冰川融化的英语作文
环境污染导致冰川融化的英语作文The Melting Glaciers: A Cry for Help from Mother NatureHave you ever seen a gigantic river of ice slowly creeping down a mountain? Those massive frozen rivers are called glaciers, and they are some of the most amazing natural wonders on our planet. Glaciers are made up of layers and layers of snow that have been compressed into solid ice over many years. They play a crucial role in our Earth's environment by storing fresh water and regulating the climate.Unfortunately, these incredible glaciers are in grave danger. They are melting at an alarming rate, and the main culprit is something that we humans have caused – environmental pollution. Let me tell you a story about how our actions are harming these magnificent glaciers and what we can do to help save them.Once upon a time, in a pristine mountain range, there lived a family of glaciers. They were the pride of the mountains, glistening in the sunlight and providing fresh water to the rivers and streams below. The animals and plants in the area thrived because of the glaciers' life-giving water.But then, something started to change. Humans began burning more and more fossil fuels like coal, oil, and gas for their factories, cars, and power plants. These fuels released harmful gases called greenhouse gases into the air. Greenhouse gases act like a thick blanket around the Earth, trapping heat from the sun and causing the planet to warm up.As the Earth's temperature rose, the glaciers began to feel the heat. Their icy bodies started to melt at a faster rate than usual. At first, it was just a trickle, but over time, the melting became more and more rapid.The once-mighty glaciers shrank in size, and their beautiful icy tongues retreated further and further up the mountains. The animals and plants that depended on the glaciers' water struggled to survive as streams and rivers dried up.The melting glaciers also caused another problem – rising sea levels. You see, when glaciers melt, all that water has to go somewhere, and it often ends up in the oceans. As more and more glaciers melted, the sea levels around the world began to rise, threatening coastal cities and communities.The glaciers cried out for help, but their voices were drowned out by the roar of human activity. Factories continued to spew out greenhouse gases, cars and trucks kept burningfossil fuels, and deforestation stripped away the trees that could have helped absorb some of those harmful gases.But there is still hope! If we act now, we can save the glaciers and protect our planet for future generations. Here are some things we can do:Reduce our energy use: Turn off lights and electronics when not in use, and try to use energy-efficient appliances. The less energy we use from fossil fuels, the fewer greenhouse gases we'll produce.Walk, bike, or take public transportation instead of driving whenever possible. Cars and trucks emit a lot of greenhouse gases, so cutting down on driving can make a big difference.Recycle and reuse items instead of throwing them away. Recycling helps reduce the need for new materials, which often requires burning fossil fuels during manufacturing.Plant trees and support reforestation efforts. Trees absorb carbon dioxide, one of the main greenhouse gases, and help counteract the warming effect.Spread awareness about the importance of protecting glaciers and the environment. Encourage friends and family to make eco-friendly choices too.Every little action we take can help save the glaciers and preserve our planet's natural beauty for generations to come. The glaciers are counting on us to be their heroes and protect them from further harm.Imagine a future where the majestic glaciers still flow proudly down the mountains, providing fresh water and supporting countless forms of life. Imagine a world where our children and grandchildren can witness these incredible natural wonders and appreciate the efforts we made to save them.The glaciers are crying out for our help. Will you answer their call and become a guardian of these icy treasures? Together, we can make a difference and ensure that the glaciers continue to grace our planet with their beauty and importance for many years to come.。
影响全球变暖的主要因素英语作文
影响全球变暖的主要因素英语作文全文共3篇示例，供读者参考篇1Global warming is one of the most pressing environmental issues facing our planet today. It has far-reaching impacts on ecosystems, weather patterns, and the livelihoods of people around the world. There are several main factors that contribute to global warming, and understanding these factors is crucial in finding solutions to combat this issue.One of the primary factors contributing to global warming is the burning of fossil fuels, such as coal, oil, and natural gas. When these fossil fuels are burned for energy, they release carbon dioxide (CO2) and other greenhouse gases into the atmosphere. These greenhouse gases trap heat from the sun, leading to a warming of the Earth's surface.Deforestation is another major cause of global warming. Trees absorb CO2 from the atmosphere and store it in their biomass. When forests are cleared for agricultural purposes or urban development, this stored carbon is released back into theatmosphere as CO2. Deforestation also reduces the Earth's ability to absorb CO2 and contributes to the loss of biodiversity.The livestock industry is also a significant contributor to global warming. Livestock, particularly cows and sheep, produce methane as part of their digestive process. Methane is a potent greenhouse gas that is even more effective at trapping heat than CO2. In addition, the clearing of land for grazing cattle contributes to deforestation and further exacerbates the issue.Another important factor in global warming is the release of refrigerants and other synthetic gases into the atmosphere. These gases, known as hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs), are used in refrigeration, air conditioning, and other industrial processes. While these gases are relatively low in concentration compared to CO2, they have a much higher heat-trapping potential and can remain in the atmosphere for decades.In addition to these main factors, other human activities such as industrial processes, waste management, and agriculture also contribute to global warming. For example, the production and use of cement release large amounts of CO2 into the atmosphere, while the decomposition of organic waste in landfills produces methane. Improper agricultural practices suchas overuse of fertilizers also release nitrous oxide, another potent greenhouse gas.While human activities are the main drivers of global warming, natural factors also play a role in the Earth's climate system. Volcanic eruptions, for example, can release large amounts of ash and sulfur dioxide into the atmosphere, leading to cooling of the Earth's surface. However, these natural factors are generally outweighed by human-induced greenhouse gas emissions in the long term.In conclusion, global warming is a complex and multifaceted issue that is driven by a combination of human activities and natural processes. Addressing this problem requires a concerted effort to reduce greenhouse gas emissions, protect and restore natural ecosystems, and transition to a low-carbon economy. By understanding the main factors contributing to global warming, we can take meaningful action to mitigate its impacts and ensure a sustainable future for generations to come.篇2Global warming is one of the biggest challenges facing our planet today. It is a phenomenon where the Earth's temperature is gradually rising due to the increase in greenhouse gases suchas carbon dioxide and methane in the atmosphere. These gases trap heat from the sun, causing the planet to warm up. There are several factors that contribute to global warming, and understanding these factors is crucial in finding solutions to combat this pressing issue.One of the main factors contributing to global warming is the burning of fossil fuels. Fossil fuels such as coal, oil, and natural gas are the primary sources of energy for powering our homes, industries, and transportation. When these fuels are burned, they release large amounts of carbon dioxide into the atmosphere, leading to the greenhouse effect. The continued reliance on fossil fuels for energy generation is a significant contributor to the rising levels of greenhouse gases in the atmosphere.Deforestation is another major factor contributing to global warming. Trees and plants absorb carbon dioxide from the atmosphere and release oxygen through the process of photosynthesis. When forests are cleared for agriculture, logging, or urban development, the carbon stored in trees is released back into the atmosphere, further exacerbating global warming. Deforestation not only contributes to the increase in greenhousegases but also reduces the planet's capacity to absorb carbon dioxide, leading to a vicious cycle of environmental degradation.The increase in livestock production is also a significant factor in global warming. Livestock farming, particularly cattle farming, produces large amounts of methane, a potent greenhouse gas that is even more effective at trapping heat than carbon dioxide. Methane is released through the digestive processes of ruminant animals such as cows and sheep, as well as during manure decomposition. The expansion of the livestock industry to meet the growing demand for meat and dairy products has led to a surge in methane emissions, contributing to the overall warming of the planet.Industrial activities, such as manufacturing, mining, and construction, also play a role in global warming. These activities release a variety of greenhouse gases and other pollutants into the atmosphere, contributing to air pollution and climate change. The burning of fossil fuels for industrial processes, the release of refrigerants and other chemicals with high global warming potential, and the destruction of natural habitats for industrial development all contribute to the deterioration of the environment and the acceleration of global warming.In addition to human activities, natural factors also contribute to global warming. Volcanic eruptions, for example, release large amounts of sulfur dioxide and ash into the atmosphere, which can temporarily cool the planet by reflecting sunlight back into space. However, these cooling effects are usually short-lived, and the overall impact of volcanic eruptions on global warming is minimal compared to human-induced factors. Changes in solar radiation, the Earth's orbital parameters, and natural climate variability also play a role in influencing global temperatures, but the current rate of global warming cannot be explained solely by natural factors.In conclusion, global warming is a complex issue that is driven by a combination of human activities and natural factors. The burning of fossil fuels, deforestation, livestock production, and industrial activities contribute to the increase in greenhouse gases and the warming of the planet. Understanding these factors and their interactions is crucial in developing effective strategies to mitigate global warming and its impacts on the environment. By reducing emissions, protecting natural habitats, and transitioning to sustainable energy sources, we can work together to address this urgent environmental challenge and create a more sustainable future for generations to come.篇3Title: The Main Factors Impacting Global WarmingIntroductionGlobal warming is a pressing environmental issue that has received increasing attention in recent years. It refers to the long-term increase in Earth's average surface temperature due to human activities. There are several main factors that contribute to global warming, including greenhouse gas emissions, deforestation, and urbanization.Greenhouse Gas EmissionsOne of the primary factors impacting global warming is the emission of greenhouse gases into the atmosphere. Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, trap heat in the Earth's atmosphere, leading to a warming effect known as the greenhouse effect. The main sources of greenhouse gas emissions include the burning of fossil fuels for energy production, transportation, and industrial activities. These emissions have been steadily increasing over the past century, primarily due to human activities such as burning fossil fuels and deforestation.DeforestationDeforestation is another significant factor contributing to global warming. Trees play a crucial role in regulating Earth's climate by absorbing carbon dioxide from the atmosphere through photosynthesis. When forests are cleared for agriculture, logging, and urban development, the carbon stored in trees is released back into the atmosphere as carbon dioxide, contributing to the greenhouse effect. Deforestation not only reduces the Earth's capacity to absorb carbon dioxide but also leads to the loss of biodiversity and ecosystems, further exacerbating the impacts of global warming.UrbanizationUrbanization is also a key factor influencing global warming. As the world's population continues to grow, more people are moving to cities, leading to increased energy consumption, transportation emissions, and infrastructure development. Urban areas are major sources of greenhouse gas emissions due to their high concentration of industrial activities, transportation networks, and buildings. The increased demand for energy in cities has led to the burning of fossil fuels, which in turn contributes to global warming.ConclusionIn conclusion, global warming is a complex environmental issue with multiple factors influencing its onset and impact. Greenhouse gas emissions, deforestation, and urbanization are among the main factors contributing to global warming, posing a significant threat to the planet's climate system and ecosystems. To address global warming effectively, it is crucial to reduce greenhouse gas emissions, promote sustainable land use practices, and invest in renewable energy sources. Only through collective efforts and global cooperation can we mitigate the impacts of global warming and ensure a sustainable future for generations to come.。

It's a huge environmental crisis that impacts everyone on the planet. But it can feel really overwhelming and make you wonder - what can one person really do to make a difference? As a student, I don't have a ton of money or power. However, there are actually lots of relatively small and easy things I can do in my daily life that can collectively have a big impact on reducing my carbon footprint. I really believe that if everyone just made some simple changes, it could go a long way towards fighting global warming.The basics of global warming are pretty straightforward. The burning of fossil fuels like coal, oil and gas releases greenhouse gases like carbon dioxide and methane into the atmosphere. These gases trap heat from the sun's rays inside the atmosphere, gradually causing global temperatures to rise. Warmer temperatures then contribute to rising sea levels, melting glaciers and sea ice, more extreme weather events like hurricanes and droughts, and other climate effects. It's a vicious cycle that we need to stop.While major change needs to happen at the levels of governments, industries and economies to transition torenewable energy sources, there's still a lot I can do personally to reduce my energy consumption and waste. Here are some of the top things I'm trying to do to go greener and be part of the solution:TransportationOne of the biggest contributors to greenhouse gas emissions is vehicles like cars, trucks and planes running on fossil fuel combustion engines. According to the Environmental Protection Agency, about 27% of total U.S. greenhouse gas emissions come from the transportation sector. That's why finding alternatives to driving is huge.For me, the easiest thing is to walk, bike or take public transportation as much as possible, instead of getting rides or driving myself. It's a simple lifestyle change that just takes a little extra effort. I'm lucky that my school and a lot of things in my city are accessible without having to use a car. If I do really need to drive somewhere, I try to carpool as much as possible to cut down on emissions.For longer trips, I try to minimize air travel when I can, or offset those emissions by supporting renewable energy projects. Vacation road trips are great alternatives - just pack some snacks and make it an adventure!At HomeA lot of energy gets wasted at home through heating, cooling, appliances, electricity and more. There are so many easy ways to cut down energy usage:• Turn off lights when l eaving a room• Unplug electronics when not in use to avoid phantom power drain• Take shorter showers• Wash clothes in cold water when possible• Air dry dishes instead of using the heated drying cycle• Properly insulate your home to reduce heating and cooling needs• Buy energy efficient LED light bulbs• Adjust your thermostat a few degrees to use less heating and ACMy family has also looked into getting a home energy audit to find other ways to be more efficient. Simple daily habits like this can really make a difference.Food ChoicesThe food we eat also has a bigger climate impact than you might think. Here are some easy food-related ways I'm cutting emissions:• Cut dow n on meat and animal products, which have a high carbon footprint from livestock contributing greenhouse gases• Avoid highly processed and packaged foods that create manufacturing and transportation emissions• Buy locally grown, seasonal fruits a nd vegetables that don't require long-distance transport• Eat more plant-based foods like beans, grains, fruits and veggies• Cut down on food waste by planning meals, using leftovers, and compos篇3How I Can Help Mitigate Global WarmingClimate change is one of the biggest challenges facing humanity today. The burning of fossil fuels, deforestation, and other human activities have led to a significant increase in greenhouse gas emissions, trapping heat in the Earth's atmosphere and causing a rise in global temperatures.

By making conscious choices in our daily lives and advocating for more sustainable practices, we can collectively make a significant impact.One of the most effective ways I can contribute to combating global warming is by reducing my carbon footprint. A carbon footprint is the total amount of greenhouse gas emissions caused directly and indirectly by an individual, organization, or product. The average American has a carbon footprint of around 16 tons of carbon dioxide equivalent per year, which is one of the highest rates in the world.To reduce my carbon footprint, I can start by making more eco-friendly transportation choices. Instead of relying on cars or other vehicles that run on fossil fuels, I can walk, bike, or take public transportation whenever possible. Not only does this cutdown on emissions, but it also promotes a healthier lifestyle and can save money in the long run.Another way I can lower my carbon footprint is by being more mindful of my energy consumption at home. Simple actions like turning off lights and electronics when they are not in use, unplugging appliances that are not being used, and adjusting the thermostat to a more energy-efficient temperature can make a significant difference. I can also encourage my family to invest in energy-efficient appliances and consider installing solar panels or other renewable energy sources if feasible.In addition to reducing my carbon footprint, I can also help mitigate global warming by adopting more sustainable lifestyle choices. This includes reducing my consumption of single-use plastics, which contribute to pollution and greenhouse gas emissions during their production and disposal. I can carry reusable bags for shopping, use a reusable water bottle, and avoid products with excessive packaging whenever possible.Furthermore, I can make more environmentally conscious decisions when it comes to my diet. The production of meat and dairy products is a major contributor to greenhouse gas emissions, as well as deforestation and water pollution. By incorporating more plant-based meals into my diet andsupporting local, sustainable agriculture, I can reduce my environmental impact and support practices that are better for the planet.Beyond individual actions, I can also play a role in advocating for larger systemic changes to combat climate change. As a student, I have a unique opportunity to raise awareness about this issue among my peers, teachers, and community members. I can join or start a school environmental club, organize awareness campaigns or events, and encourage my school to implement more sustainable practices, such as recycling programs, energy-efficient building upgrades, and the incorporation of environmental education into the curriculum.Additionally, I can use my voice to influence policy decisions at the local, state, and national levels. By participating in peaceful protests, writing letters to elected officials, and supporting organizations that advocate for environmental protection, I can push for stronger regulations on greenhouse gas emissions, increased investment in renewable energy sources, and the implementation of policies that promote sustainability.It is important to recognize that addressing global warming is not just an environmental issue, but also a social justice issue. The impacts of climate change disproportionately affectmarginalized and vulnerable communities, exacerbating existing inequalities and contributing to displacement, food insecurity, and health problems. By advocating for climate action, I am also advocating for a more just and equitable world for all.While the task of mitigating global warming can seem daunting, it is crucial to remember that small actions can lead to significant change when multiplied by millions of people around the world. By making conscious choices in my daily life and using my voice to advocate for sustainable practices, I am contributing to a movement that aims to protect our planet and ensure a livable future for generations to come.In conclusion, as a student, I have the power to make a meaningful difference in the fight against global warming. By reducing my carbon footprint, adopting sustainable lifestyle choices, advocating for systemic changes, and raising awareness about this critical issue, I can be part of the solution. It is our collective responsibility to take action and work towards a more sustainable and equitable future for all. The time to act is now, and the change starts with each and every one of us.。
全球变暖对海洋影响的温室效应 Greenhouse Effect on Oceans 英语作文
Greenhouse Effect on Impact of Global Warming on Oceans We have all experienced a little bit of the effect of the greenhouse gases accumulating in the atmosphere and climate change in the year 2020. Undoubtedly, the catastrophic and natural calamity that is happening in the year 2020 is the result of constant degradation of natural resources, global warming, climate change and how it has impacted the dynamics of ecology. In this particular greenhouse effect essay on impact of global warming on oceans, we shall be talking about how greenhouse effect impacts theocean and how that will, in turn, impact the entire water cycle of our ecology.Long and Short Essays on Greenhouse Effect On Impact Of Global Warming On OceansThe melting of the ice caps, the forest fires, earthquakes and increase in the average temperature of the earth are some of the very few impacts of global warming and climate change that we are already witnessing in the year 2020. If we can put it in the form of a birds point of view, then what we are witnessing right now is just a trailer for what is yet to come,which according to experts, is worse than what we are already witnessing in the year 2020.In this greenhouse effect essay on impact of global warming on oceans, we shall be talking about how global warming and accumulation of greenhouse gases such as nitrogen, methane, hydrogen and carbon dioxide has adverse effects on oceans with aquatic life and other water bodies on the earth.Due to irresponsible usage of natural resources and burning of fossil fuels coming from our vehicles, factories, burning of forests and burning of crops, the amount of carbon dioxide,nitrogen, hydrogen, methane and other greenhouse gases in the atmosphere is increasing every day. This has an adverse impact on the water cycle of nature. The water from the oceans, due to the heat from the sun, evaporate and starts condensing in the atmosphere to form clouds. These clouds, after condensation, and after attaining enough moisture, burst and the rain starts pouring on land and oceans.This whole cycle is important for the survival of the planet and living beings in it. But due to industrialisation, globalisation and irresponsibleuse of natural resources, the entire dynamics of this water cycle is being affected. Scanty rainfall floods, droughts and unpredictable climatic conditions are some of the effects of global warming on oceans. The cyclone Amphan that we witnessed on the Western coast of India on the states of West Bengal, Orissa and Bangladesh has caused catastrophic and unimaginable destruction to life and property. These storms and earthquakes that we are witnessing is because of the disturbance in the water cycle and the ocean diversity of the planet.Global warming also affects the aquatic life that is present in our oceans. According to scientists, due to an increase in the average temperature of the earth, the oxygen level in the ocean water is reducing as a result of which certain aquatic life are becoming extinct. Irresponsible dumping of toxic wastes in our oceans such as plastic waste, oil refinery waste and nuclear waste is having an adverse effect on the aquatic life of the ocean. It is estimated that an area as large as India is being filled with plastic and other sorts of dangerous waste in the Pacific ocean. What human beings have failed to understand is that these wastes percolate into the aquatic lifeand water which will eventually be consumed by human beings and thereby poisoning the entire food cycle of our ecosystem.Aquatic life and water cycle are very few effects of global warming on oceans. If the accumulation of greenhouse gases in the atmosphere does not reduce, natural calamities like tsunami, floods, storms, cyclones and volcanic eruptions will become an everyday phenomenon and the life as we know it will come to an end.Short Essay on Greenhouse Effect Impact Of Global Warming On OceansIndustrialisation, urbanisation and population explosion has resulted in increased accumulation of poisonous greenhouse gases in the atmosphere. These poisonous gases have cascading negative impacts on the oceanic ecosystem of our planet. From affecting the water cycle to creating unpredictable climatic conditions, the effect of global warming on oceans are many. If the water cycle is affected, the oceanic currents will not be predictable by scientists and as a result of which the damage caused due to cyclones, storms and floods will increase.Other than affecting human beings and their property, the increasing pollution of water and air is also having a negative effect on aquatic life. Dumping of oil, nuclear waste, plastic waste and other such dangerous chemicals in the ocean has led to the poisoning of the aquatic life and many aquatic beings have become extinct over the years. This poisoning of ocean, air and land will eventually come back to us in the form of the food we eat and it starts poisoning the human population.I would like to conclude by saying that global warming is one of the biggest challenges for theinternational community. Every country has to come forward to reduce carbon footprint and adopt environmental-friendly green energies such as wind energy, solar energy or nuclear energy.10 Lines on Greenhouse Effect Essay On Impact Of Global Warming On OceansGlobal warming is a phenomenon in which the average temperature of the earth increases due to the accumulation of greenhouse gasesGreenhouse gases are produced by the burning of fossil fuels in factories, in vehicles run by petrol or diesel car and by burning of cropsCarbon dioxide is the most harmful greenhouse gas that is resulting in the warming of our planet graduallyImpact of global warming results in the melting of ice caps and affecting water cycle on oceans which is basically harming the balance of our natural cycleGlobal warming in the future will lead to a decrease in oxygen content in oceans which canultimately affect the aquatic life in our water bodiesProper policies should be formulated to reduce the carbon footprint of countriesIt is said that by the year 2030, the average temperature of the earth will increase by 2.5 degree CelsiusThe impact of global warming on oceans is witnessed through floods, storms, cyclones, hurricanes and other such unpredictable natural calamitiesThe poisoning of the food we eat, the air we breathe and the water we drink is the result of man’s greed for economic growth at the cost of natureMore than half of earth is covered by water and if the water bodies are slightly disturbed from its natural balance, then scientists predict that floods and tsunamis on a large scale can eliminate human civilization forever >FAQ’s on Greenhouse Effect Essay On Impact Of Global Warming On OceansQuestion 1.How does global warming affect oceans?Answer:Due to an increase in the average temperature of the earth, the water in the oceans absorb the greenhouse gases and hence the oxygen content in the water reduces as a result of which aquatic life will be affectedQuestion 2.What is Ocean acidification?Answer:Ocean acidification is a gradual process in which the water in the ocean absorbs the greenhouse gases and their pH level increases making life for aquatic animals difficult to surviveQuestion 3.How to prevent global warming?Answer:Reducing carbon footprint and use of alternative, green forms of energy sources like nuclear energy and wind energy will help in the reduction of global warmingQuestion 4.What happens if global warming is not prevented?Answer:If global warming is not prevented, the water cycle, the food cycle and basic structure of the ecological dynamics will be affected and will lead to many natural calamities which will eventually lead to the destruction of life and property on a massive scale。

全球变暖的原因以及应对措施英语作文
全球变暖的原因以及应对措施英语作文全文共3篇示例，供读者参考篇1Global warming is a major environmental issue that has been causing concern for decades. The main cause of global warming is the increased emission of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, into the atmosphere. These gases trap heat from the sun, leading to a rise in global temperatures.There are several human activities that contribute to the emission of greenhouse gases. The burning of fossil fuels for transportation, electricity generation, and industrial processes is one of the biggest sources of carbon dioxide emissions. Deforestation, agriculture, and waste management also release significant amounts of greenhouse gases into the atmosphere.To combat global warming, it is essential for individuals, communities, and governments to take action. One of the most effective ways to reduce greenhouse gas emissions is to transition to cleaner and renewable sources of energy, such as solar, wind, and hydroelectric power. By investing in renewableenergy infrastructure and improving energy efficiency in buildings and transportation, we can significantly reduce our carbon footprint.Another important step in addressing global warming is to protect and restore forests, which act as natural carbon sinks by absorbing and storing carbon dioxide. Forest conservation efforts, such as afforestation and reforestation, can help mitigate the impacts of climate change. Sustainable land management practices in agriculture, such as conservation tillage and agroforestry, can also contribute to reducing greenhouse gas emissions.In addition to mitigation efforts, it is crucial to adapt to the impacts of global warming that are already being felt. Climate change is causing more frequent and severe heatwaves, storms, droughts, and floods, which can have devastating consequences for communities and ecosystems. Building resilient infrastructure, implementing early warning systems, and enhancing disaster preparedness are essential for reducing vulnerability to climate-related hazards.Education and awareness-raising are also key components of addressing global warming. By increasing public understanding of the causes and consequences of climatechange, we can mobilize individuals and communities to take action. Promoting sustainable lifestyles, such as reducing waste, conserving water, and choosing eco-friendly products, can make a significant difference in reducing our environmental impact.In conclusion, global warming is a complex and urgent issue that requires collective action at all levels. By implementing mitigation and adaptation measures, investing in renewable energy, protecting forests, and raising awareness about climate change, we can work towards a more sustainable and resilient future for our planet. It is up to each and every one of us to take responsibility for our actions and make a positive contribution to combating global warming.篇2Global warming has become a major issue in recent years, with rising temperatures and extreme weather events becoming more frequent. The primary cause of global warming is the increase in greenhouse gas emissions, primarily carbon dioxide, methane, and nitrous oxide, which trap heat in the Earth's atmosphere and cause the planet to warm up.There are several sources of these greenhouse gas emissions, including the burning of fossil fuels for energy production,deforestation, industrial processes, and agricultural activities. The reliance on fossil fuels such as coal, oil, and natural gas for energy production is a major contributor to global warming, as the combustion of these fuels releases large amounts of carbon dioxide into the atmosphere.Deforestation is another significant driver of global warming, as trees absorb carbon dioxide from the atmosphere and store it in their biomass. When forests are cleared, this stored carbon is released back into the atmosphere, contributing to the greenhouse effect. In addition, agricultural activities such as livestock farming and rice cultivation produce methane and nitrous oxide, two potent greenhouse gases that contribute to global warming.To tackle the issue of global warming, it is essential to reduce greenhouse gas emissions and transition to a more sustainable and low-carbon economy. One of the key measures to achieve this is the adoption of renewable energy sources such as solar, wind, and hydropower, which produce electricity without emitting greenhouse gases. Investing in energy efficiency measures and promoting energy conservation can also help reduce emissions from the burning of fossil fuels.Another important strategy to combat global warming is reforestation and afforestation, which involves planting trees to absorb carbon dioxide from the atmosphere and store it in their biomass. Protecting existing forests and restoring degraded ecosystems can help sequester carbon and mitigate the impacts of deforestation on the climate.In the agricultural sector, implementing sustainable farming practices such as organic agriculture, agroforestry, and conservation agriculture can help reduce greenhouse gas emissions and promote soil carbon sequestration. Reducing food waste and shifting towards a plant-based diet can also help lower emissions from agriculture and mitigate the impacts of global warming.In addition to mitigation measures, it is also important to adapt to the impacts of global warming and build resilience to climate change. This includes investing in climate-resilient infrastructure, developing early warning systems for extreme weather events, and supporting vulnerable communities to cope with the effects of global warming.Overall, addressing global warming requires a coordinated and comprehensive approach that involves government action, private sector investment, and individual behavior change. Bytaking decisive action to reduce greenhouse gas emissions and build resilience to climate change, we can mitigate the impacts of global warming and create a more sustainable future for future generations.篇3Global warming has become one of the most pressing issues facing our planet in recent years. The rise in average global temperatures is believed to be caused by a variety of factors, ranging from natural causes to human activities. In this essay, we will discuss the reasons behind global warming and the possible solutions to mitigate its effects.One of the primary causes of global warming is the burning of fossil fuels such as coal, oil, and natural gas. When these fuels are burned, they release carbon dioxide and other greenhouse gases into the atmosphere, which trap heat and cause the Earth's temperature to rise. Deforestation is another major contributor to global warming, as trees absorb carbon dioxide and release oxygen into the atmosphere. As more trees are cut down, the amount of carbon dioxide in the atmosphere increases, leading to higher temperatures.In addition to human activities, natural factors such as volcanic eruptions and solar radiation can also contribute to global warming. However, the overwhelming consensus among scientists is that human activities are the primary driver of the current rise in global temperatures.To combat global warming, it is essential to reduce our reliance on fossil fuels and transition to renewable sources of energy such as wind, solar, and hydropower. By investing in clean energy technologies and improving energy efficiency, we can reduce our carbon footprint and slow the rate of global warming. Additionally, reforestation efforts can help to offset the carbon emissions produced by human activities and restore balance to the Earth's ecosystem.Individuals can also take steps to reduce their impact on the environment and combat global warming. Simple actions such as driving less, recycling more, and using energy-efficient appliances can make a significant difference in reducing carbon emissions and preserving the planet for future generations. Educating others about the importance of environmental conservation and advocating for policy changes at the local, national, and global levels can also help to address the root causes of global warming.In conclusion, global warming is a complex issue withfar-reaching implications for the future of our planet. By understanding the causes of global warming and taking proactive measures to address them, we can work together to build a more sustainable and livable world for ourselves and future generations. It is up to each of us to do our part in combating global warming and protecting the environment for years to come.。
