The climate change in China shows a considerable similarity to the global change, however, there still exist significant differences between them. In the context of the global warming, the annual mean surface temperature has significantly increased during the past 100 years, with slightly greater magnitude of temperature increase than the globe . The precipitation trends during the last 50 and 100 years are not obvious ,but since 1956 it has assumed a weak increasing trend. The frequency and intensity of main extreme weather and climate events have also assumed significant change. The research has shown that the CO2 emission in China has continuously increased and the sum of positive radiative forcings produced by greenhouse gases is responsible for climate warming. The projection of climate change for the 21st century has indicated that in the future 20-100 years, the surface temperature will continue to increase and precipitation also has an increasing trend.
