气候变化英语文章

Weather surrounds us all the time. We need to choose which clothes I need to wear depend on the weather. Earth’s mild climate even ensures that we can grow food and enjoy a happy life. In a word, weather influences our life deeply.

Climate change means a big change in the world’s climate and describes the process by which the overcall climate moves from one average to a new average. The climate has changed a lot. 20,000 years ago was the last Ice Age. Nowadays, the climate of earth is changing because of us. The effects of climate change also are happening to the world’s rain. A lot of areas often happened long droughts, big floods, strong winds and storms. Many people were killed and lost their family. The extreme weather is happening more often than before because of climate change. For example, the average temperature has risen 1.2 degrees in January from 2010 to 2013 and the highest temperature even get to 45.7 degrees in Adelaide.

In recent years, scientists have noticed that earth’s average temperature has been rising. The phenomenon is referred to as global warming. Global warming is created by complex changes in the atmosphere, which are caused by increases in greenhouse gases. Greenhouse gases are special gases in the atmosphere, which have kept the earth’s temperature constant for the past 5000 years. The common greenhouse gases are carbon dioxide. Carbon dioxide occurs naturally in the atmosphere, but humans also generate them. When we burn fossil fuels such as coal, gas and petroleum. More fuel is burned , the more carbon dioxide is produced and discharged it in the atmosphere. More and more greenhouse gases become part of the atmosphere, more heat is trapped and the earth’s overall temperature rises.

Climate change is a global problem. All the world governments need to work together to find answers to the problem. In 1992,a lot of countries agreed to work together in order to solve those problems. They made a group, the UN Framework Convention on Climate Change (UNFCCC). Their task is making a plan for against climate change. In 1997,the UNFCCC made its plan. The plan was “each country has a limit to its greenhouse gases and they shouldn’t put more greenhouse gases into the atmosphere than its limit”. In that case, some counties have to use environmentally friendly/sustainable/renewable energy instead of burning oil or fuel.

Scientists have been developing ways of generating electricity that produce less carbon dioxide. However, some of these have disadvantages and limitations.

Wind power creates no greenhouse gases or air pollution Modern turbines don’t have noise pollution.

Wind energy is renewable energy

The cost of wind energy is expensive

Wind energy has a lot of limited factors for example if the wind is not blowing, wind turbine can’t work

Nuclear power can produce huge amounts of electricity. Running a nuclear power plant is relatively cheap.

Nuclear power does not produce greenhouse gas emissions.

Nevertheless, the risks of nuclear power are too great. For example, the Fukushima Nuclear Power Plant in Japan was destroyed because of an earthquake. High levels of nuclear
