climate change

There are several reasons causing the climate change in China. Roughly, we divide them into two kinds, one is natural factor and the other is human factor.

Many natural factors lead to the climate change, such as the volcano eruption, the change of orbit around the earth and solar radiation. But these are not the main catalysts and cannot be controlled by humans. What really matters and can be controlled is human activities that result in the rapid climate change in China.

According to IPCC Third assessment report, the main climate change is global warming. Global warming is caused in part by the emission of greenhouse gases, including carbon dioxide and methane. These gases are emitted naturally. They are also the result of burning fossil fuels, especially coal and petroleum products. In recent years, because of the industrial development and the increase in number of cars ,buses and other vehicles, more and more greenhouse gases are emitted,which make the global warming problem more and more serious.

This is a good start, but you need to add specific details about how the burning of fossil fuels is proceeding in China. can you find any statistics about this?
