1、 Chinese name: Liu LixiangEnglish name: Lida Class: One Global WarmingHave you fond the global getting warm? It is easy to know that it is due to the global warming. Global warming is a kind of natural phenomenon. Global warming is a period of time when the earths atmosphere and oceans temperature r

2、aise what was caused by human factors. The United Nations has a target for the worlds governments to reduce Global warming. (United Nations 2009a) First,it will outline some of the causes of Global warming. After that,it will compare the Total emission of CO2 per capital in 2000 between developed an

3、d developing nation. Finally it will compare per capital emission of CO2 in developing regions.There are many reasons to lead to the global warming. First, in recent years, the population explosion that cause global warming is one of the major factors. At the same time, it also poses a serious threa

4、t to balance in natural ecological environment. Then, atmospheric pollution of the environment, the pollution of environment is a serious problem what causes the global warming. Third,Species extinction acceleration. Because it exists global warming so the species extinction acceleration is very fas

5、t. The consequences of global warming will lead to redistribution of rainfall, the ice melted and the sea level rise. Global warming will harm the balance of natural ecosystem, the threat of human food supply and living environment.In different regions carbon dioxide emissions are different. The mai

6、n reason of Global warming is the main reason is because of greenhouse gases (carbon) emission overmuch. However, (United Nations 2009a) For example, Developed Regions and the developing Regions are vary. In2000 11.8% of CO2 emission in developed regions, whereas the number was 2% in developing regi

7、ons. In the other words, the number in developed regions is five times as many as developing regions. Form table 1, we can find that developed regions have more total emission of CO2 per capital than developing regions.Table 1: Global Warming Rates: Developing and Developed Regions, 2000(United Nati

8、ons 2009a)Developing CountriesDeveloped CountriesGlobal Warming per capita2.011.8The Developing Regions are also different. Northern Africa, Sub-Saharan Africa, Latin America &the Caribbean, Eastern Asia, Southern Asia, South-Eastern Asia, Western Asia and Oceania also not the same. Western Asia is

9、considerably more than Oceania. Northern Africa is slightly less than in Eastern Asia. From table 2, we can find that western Asia is the most regions about per capital emission of CO2 in developing regions.The consequences of global warming climate became more: Firstly, warm, ice melted and the sea

10、 level rise, causing the gulf coast, estuary and natural ecological environment, destroys. Secondly, many of the islands will disappear. Third, infectious disease, flood, expand to human health hazard. Global warming will harm human health. In conclusion, global warming remains a serious problem in

11、the world now. I think it is a duty that all the countries of the world should work to finish it so that we can found a clear sky. Let us together project our homeland.
