This review paper summarizes features in climate change in China over the past century,anthropogenic changes in global carbon cycle,and the simulated climatic effects of greenhouse gases in climate models. Over the past 100 years,the observed annual mean surface air temperature in China exhibited an overall increase. In the recent 50 years,a warming prevailed in China in winter,whereas a cooling was found in the middle and lower reach of the Yangtze River in summer. Human activities have been considered as the major driver of global warming. The biosphere has been considered as the major sink for missing carbon removal. Most global climate models can now reproduce the changes in annual mean surface air temperature over the past decades. With both natural and anthropogenic forcings in climate models,the Intergovernmental Panel on Climate Change(IPCC)Fourth Assessment Report(AR4)multi-model ensemble simulated a warming trend of 0.oft-com:office:smarttags" />67℃/100a over 1880~1999,which is very close to the observed trend of 0.53℃/100a in this time period. Because climate change is influenced by both the natural variability and anthropogenic forcings in the Earth system,further understanding of the impact of global carbon cycle on climate change in China needs to reduce model uncertainties associated with the simulation of the natural and anthropogenic forcings,especially those associated with the estimates of the sources and sinks of carbon in the biosphere.
