全球变暖(英语)--global-warming
in sea levels worldwide
Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East coast of the US. However, many nations around the world will experience the effects of rising sea , which could displace millions of people.
Increase in usage of chemical fertilizers on croplands
Carbon dioxide emissions from fossil fuel burning power plants
Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.
Deforestation , especially tropical forests for wood, pulp, and farmland
The use of forests for fuel is one cause of deforestation. Forests remove and store carbon dioxide from the atmosphere, and this deforestation releases large amounts of carbon, as well as reducing the amount of carbon capture on the planet.

Disappearance of coral reefs
A report on coral reefs from WWF says that in a worst case scenario, coral populations will collapse by 2100 due to increased temperatures and ocean acidification . The 'bleaching' of corals from small but prolonged rises in sea temperature is a severe danger for ocean ecosystems, and many other species in the oceans rely on coral reefs for their survival.
Methane emissions from animals , agriculture such as rice paddies, and from Arctic seabeds
Methane is another extremely potent greenhouse gas, ranking right behind CO2.When organic matter is broken down by bacteria under oxygen-starved conditions as in rice paddies, methane is produced .

关于全球变暖globalwarming的英文文章
关于全球变暖global warming的英文文章下面就给你cram恶补一下关于global warming的英文知识，让你在聊起环保话题也游刃有余!什么是全球变暖? What is Global Warming? Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.自然界有正常的“温室效应” Earth’s natural greenhouse effect Earth’s temperature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet. As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane. When they absorb the energy radiating from Earth’s surface,microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight. This absorption and radiation ofheat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface t emperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.加强版“温室效应” The enhanced greenhouse effectWhat has scientists concerned now is that over the past 250 years, humans have been artificially raising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly by burning fossil fuels, but also from cutting down carbon-absorbing forests. Since the Industrial Revolution began in about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methane levels have increased 148 percent.。

高分英语作文1：global warmingIn recent years, global warming has become a hot issue of people's concern. It is caused by serious air pollution. With the increasingly serious environmental pollution, global temperature rises sharply, and disasters such as drought, flood and glacier melting also follow.Therefore, we need to protect our earth and fight against it. We should start from small things and make contributions to protect our home offer.中文翻译：近年来，全球变暖已成为人们关注的热点问题，它是由于严重的空气污染造成的，随着环境污染的日益严重，全球气温急剧上升，干旱、洪水和冰川融化等灾害也随之而来，因此，我们需要保护我们的地球并与之抗争我们应该从小事做起，为保护我们的家园做出贡献。
万能作文模板2：全球变暖Many people think that human activities cause the earth's temperature to rise. They say that global warming will have terrible consequences for our environment, such as drought and flood. What should the government do to help prevent global warming? Give your advice and reasons.The earth's temperature is changing rapidly, so thereare many climate changes, such as heat waves, droughts and floods. Scientists believe that this is human activity As a result, if governments don't take action to help prevent global warming, it could be a disaster. They can act in three ways: supporting research, laws and the public aware of the situation first.s can support research. For example, they should encourage companies to develop less polluting cars. They should also support alternative energy sources for wind and water Instead of oil and coal, they should organize meetings to discuss the impact of greenhouse gas emissions and possible solutions.Second, they should enact laws to limit the amount of greenhouse gases that companies emit. Private companies should be rewarded for complying with these laws, and they should be punished for creating pollution. Finally, everyone is affected by global warming.Therefore, the government should involve individuals in the problem-solving process, which is very important to encourage families to use more efficient light bulbs or less hot water to save energy as much as possible. They should also encourage the public to recycle, which is mandatory for everyone. Another way to save energy is through the public transport .The government should spend money on public transport to make it as easy as possible for the public to summarize energy conservation. Obviously, the government can do a lot to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the earth.中文翻译：许多人认为人类活动导致地球温度升高，他们说全球变暖将对我们的环境造成可怕的后果，例如旱灾和水灾应该做些什么来帮助防止全球变暖给你的建议给出理由地球温度正在迅速变化，因此出现了很多气候变化，如热浪、干旱和洪水科学家认为这是人类活动的结果，如果不采取行动来帮助防止全球变暖，这可能会成为一场灾难他们可以通过三种方式采取行动：支持研究、制定法律和让公众首先了解情况，可以支持研究，例如，他们应该鼓励公司开发污染更少的汽车，他们还应该支持风能和水的替代能源，而不是石油和煤炭，他们应该组织会议讨论温室气体排放的影响和可能的解决方案第二，他们应该制定法律公司排放温室气体的数量公司应该因为遵守这些法律而受到奖励，他们也应该因为制造污染而受到惩罚。
英文版全球气候变暖原因
英文版全球气候变暖原因O悬赏分:20 -解决时间：2007-7-6 19:18提问者：zhangxiaoyu996 - 一级最佳答案Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.Global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.3 ±0.32 °F) during the past century. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations," which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes have probably had a small warming effect from pre-industrial times to 1950, but a cooling effect since 1950. The basic conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. The American Association of Petroleum Geologists is the only scientific society that rejects these conclusions, and a few individual scientists also disagree with parts of them.Climate models referenced by the IPCC project that global surface temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100. The range of values reflects the use of differing scenarios of future greenhouse gas emissions and results ofmodels with differences in climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if greenhouse gas levels are stabilized. This reflects the large heat capacity of the oceans.全球气候变暖用英文怎么说O悬赏分：0 -解决时间：2006-6-27 00:19 有没有相关的英文文章.谢谢提问者：鲍蔓薇-三级最佳答案global warming 或者green house effect 温室效应，又译全球气候变暖The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60°F colder. Because of how they warm our world, these gases are referred to as greenhouse gases.Have you ever seen a greenhouse? Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter. Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter.The Earth’s atmosphere is all around us. t is the air that we breathe. Greenhouse gases inthe atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface, land, water, and biosp here absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up.The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.联合国关于全球气候变暖的报道DATE=3/2/01TITLE=ENVIRONMENT REPORT - UN Climate Change ReportBYLINE=Cynthia Kirk(Start at 59" ) This is Bill White with the VOA Special English ENVIRONMENT REPORT.A new United Nations report says poor countries would(1)suffer the most from the effects of the warming of theEarth.

全球变暖Global warming (英文)
Global warmingGlobal warming refers to the rise of the climate of the earth's atmosphere and the oceans due to the greenhouse effect. Between 1906 and 2005, the global average temperature of the atmosphere near the ground increased by 0.74 degrees Celsius. In general, the scientific community has found that the rate of observable climate change over the past 50 years is twice that of the past 100 years, so it is inferred that climate change in this period is driven by human activities. The heat caused by the temperature rise will provide a huge kinetic energy for the air and the ocean, resulting in large typhoons, hurricanes, tsunamis and other disasters. The rising temperature will result in Glacier melting and sea level rise which cause the coastal ecological environment disaster.Global warming is a nature-related phenomenon. Human activities like burning fossil fuels, such as oil, coal, etc., deforestation and incineration will produce a lot of carbon dioxide, or greenhouse gases. These greenhouse gases can penetrate through the visible light from the solar radiation, absorbing the long-wave radiation from the earth and the infrared from the ground. It results in the rise of the Earth's temperature rise and facilitating the greenhouse effect. When the greenhouse effect continues to accumulate, it results in the imbalance of ground gas system absorption and emission of energy. The energy constantly accumulates, resulting in rising temperatures and global warming. Deforestation, land reduction and other land use changes have changed indirectly in the atmosphere. The increase in the concentration of greenhouse gases can also lead to global warming.Due to the increase in the population, the annual emissions of carbon dioxide produced by human activities alone directly leads to the increase of the atmospheric carbon dioxide. It directly affects the Earth's surface climate change. Mineral combustion emission caused by electric energy consumption is also one of the main reasons for the global warming.The growing environmental pollution has become a major global problem, but also one of the major factors leading to global warming. In the 21st century, research on global climate change has clearly pointed out that the temperature of the Earth's surface has risen since the end of the last century.Sea level changes are rising. According to the experts’ predict ion, in the middle of the next century, the sea level may rise 50cm. If there are no measures taken, it willdirectly lead to the destruction of fresh water resources and pollution and other adverse consequences. In addition, a large number of toxic chemical wastes and solid wastes produced by human activities continuously discharge into the sea. The major leaking oil events in ocean and the destruction of the ecological environment in coastal areas caused by human activities are the main factors that cause the destruction of the ecological environment of sea. The toxic chemicals not only pose a serious threat to human survival, but also to the ecological environment of the Earth's surface.Human activities cause serious damage to the land due to excessive deforestation, agricultural production and grazing, resulting in large-scale floods and dust storms which cause significant economic losses to the society and worsening the ecological environment.。

• 有些专家认为，气候变暖，或许能造福人类。 • 英国皇家科学院院长梅伊勋爵，对全球暖化忧心忡忡，他 说：“人类从未遇过这种遍及全球的威胁；就像一列火车 失控而且持续加速，如果我们现在不制止，未来将更难以 阻挡。” • 伦敦大学生物地理学荣誉教授菲力普·史托特说：“如果 气候变迁可以投票决定，大家都会选择比较暖和的天气。 寒冷的影响，在各方面包括农业、经济、人类健康等，都 是百害而无一利。” • 美国俄勒冈州立大学农业经济学教授理查·亚当斯说： “我对未来感到乐观。农民的本领令我叹为观止，担心爆 发大规模饥荒，根本是杞人之忧。”
• 全球变暖指的是在一段時間中，地球的大 气和海洋溫度上升的現象。 • 在20世紀，全球平均接近地面的大氣層溫 度上升了攝氏0.74度。 普遍来说，科学界 0.74 发现过去50年可广场的气候改变的速度是 过去100年的双倍，有理由认为该时期的气 候改变是有人类活动所推动。
• 由环境污染引起的温室效应是指地球表面 变热的现象。，它会带来以下列几种严重 恶果： • 1) 地球上的病虫害和传染疾病增加； • 2) 海平面上升； • 3) 气候反常，海洋风暴增多； • 4) 土地干旱，沙漠化面积增大。
• 研究发现气候暖化加速黄河源冻土退化
• 中国科学院的研究人员发现，气候持续转暖加速了黄河源 冻土退化，多年冻土下界最大升高了80米。 • 近数十年来，受全球气候变暖和日趋频繁的人类经济活动 的影响，源区主河道断流、水土流失、草地生态系统持续 退化、土地沙化及荒漠化日趋严重。黄河源区多年冻土加 速退化使赋存于高寒草地和维系高寒草地生长发育的多年 冻土上部的冻结层 • 上水水位持续下降， • 从而引发和加剧了 • 高寒草地的退化、 • 沙漠化、盐渍化以 • 及水环境变异。
