    In recent years,controversy about global warming and its mechanism have reached an unprecedented level. Partly,this is due to the fact that climatic change is moving from a pure topic of atmospheric science and evolving into an issue associated with carbon reduction,carbon tax and other national interests. Since having been highly economy-linked,the issue may inevitably deviate from pure science discussion and leave room for unfairness to step in. Based on in-depth review and analysis,we come to conclusions as follows: 1) Because rapid urban development in last century had affected temperature measurements,the heating island effect should be considered to avoid the overestimation of global warming; 2) The contributing factors,human or natural ones,of the warming during last century remain uncertain,so the warming rate may be 0. 4 ℃ or even lower,if the heating island effect is corrected,; 3) At 10 000-year time scale,global climate is in its cooling trend,in contrast to the warming at 100-year time scale,and the latter can be explained more reasonably as one of secondary fluctuations of the former; 4) Either in the past or at present,the change of atmospheric CO₂ concentration has always lagged behind that of temperature. In other words,temperature drives CO₂ but not vice versa.
