    Abstract

    According to a report by UN Intergovernmental Panel on Climate Change(IPCC),the earth′s mean air temperature rose by 0.74 ℃ during last century,as a result of anthropogenic emissions of greenhouse gas.However,many conclusions of the report are controversial.What is the contribution of anthropogenic greenhouse gas emissions to global warming? Does human factors play a key role in global warming? Can the 0.74 ℃ be explained as one of secondary fluctuations in the general cooling trend of global climate? We argue that since the Quaternary,climatic changes on earth were mainly controlled by the periodic change of solar radiation.Since the late Holocene the global climate showed a cooling trend,but there were many secondary fluctuations,whose changes of mean air temperature could range between 0.5 ℃ and 6 ℃.Therefore,we would rather consider the warming in the IPCC report as one of such secondary fluctuations.
