An Inconvenient Truth

Global Warming is caused by many things and every day scientists come out with a new one. The causes are divided into two groups, natural causes and man-made. One natural cause is the big release of methane gas in the Arctic. The other causes are the man-made causes which are the most important reason for this big issue such as using fossil fuels. These led to carbon dioxide emissions from trucks, carbon dioxide from airplanes, and carbon dioxide from buildings. We have to keep our sight clear and try to stop global warming from spreading. And we have to know how much loss global warming may cause to the world.

GLOBAL WARMING

Nowadays the most important problem in the world is global warming. Everybody believes that the world temperature is increasing because of carbon dioxide from our cars, factories and power plants and so many others. Furthermore, studies showed that the world temperature has risen by about 1F in the last century. Moreover, climate change has been caused by the human activities in their daily lives.

There are lots of causes which make global warming happen. Firstly, is atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases); scientists say that temperatures would be much lower than they are now without the greenhouse effect. Secondly, is air pollution caused by cars, trains, factories and fires. China is the largest source of global warming pollution in the world.

Finally, I think we have to use gas and carbon less. Everybody has to change his way of life, so that we can avoid this problem in the future.
