1、 Weather surrounds us all the time. We need to choose which clothes I need to wear depend on the weather. Earths 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 worlds climate and describe
2、s 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 worlds rain. A lot of areas ofte
3、n 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 tem

8、. 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 earths temperature constant for the past 5000 years. The com
9、mon 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 greenhous
10、e gases become part of the atmosphere, more heat is trapped and the earths 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

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 electric

Wind energy is renewable energy The cost of wind energy is expensive Wind energy has a lot of limited fact
17、ors for example if the wind is not blowing, wind turbine cant workNuclear 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 F
18、ukushima Nuclear Power Plant in Japan was destroyed because of an earthquake. High levels of nuclear radiation spread throughout the area. The Chernobyl accident in Russia resulted in everyone abandoning this area until recently.The cost of building a nuclear power plant is very expensive and they h

Australia has the largest deposits of uranium in the world.Every country has their own ideas and plans, so they may not be able to collaborate successfully. The Kyoto Protocol did not start until2005
20、because the United States, one of the biggest producers of carbon dioxide, has not yet agreed to the protocol. The United States is afraid of losing huge amounts of money and even happen economic recession, if they reduce discharge carbon dioxide. Another problem is that the developed countries shou
21、ld provide new technology and funding to developing countries to help them reduce carbon dioxide emissions. However, some developed countries do not want to help. On the contrary, developed countries limit the use of energy for developing countries. This is not fair for some developing countries who
22、 want to create a better life for their people which means using more energy.During the summer holiday, I read a book about climate change: Climate Change by Barnaby Newbolt. It was easy to read and it helped me to understand the problems associated with climate change. The concept of climate change
23、 and social tensions I researched from this book. Although the information is not very detailed, it is valid and objective. I have also borrowed two other books: Climate Change by Angela Crocombe and World at Risk: Climate Change by Andrew Solway. I found some reliable information and many visuals.
24、Although I summarized that information, the number of words is still over 600 words. I think climate change is a complex concept that includes a lot of areas such as environment, atmosphere, chemistry and politics. Too many words will lead to my oral presentation becoming boring.
