Abstract:Global climate is experiencing an obvious warming.This paper summarizes the main findings of climate change researches conducted globally,with an emphasis of results of the recent studies done in China.A more evident change in climate has been found in the country for both the past and the future.If the change in the past50years could be attributed to the increased atmospheric CO 2 concentration,and if the projected changes for the coming decades will come to be true,the impacts of the anthropogenic climate change will be very significant,and they have to be considered more seriously.
