从哲学的基本原理出发，引用地史及水文气象资料探讨了全球气候变化问题，指出全球气候一直在变化；气候变化的动力主要在天在地而不在人；当今的气候变化可能只是气候变化总过程中的一个波动阶段而非永远的趋势,且其变幅并未超出历史上气候变化的范畴。因此，不能断言全球气候变暖是由于人为排放CO₂所致。所以对于不同时空条件下的气候变化应当具体矛盾具体分析具体解决，进而提出了中国应对气候变化的对策建议。

Based on basic principle of philosophy, the problem of global climate change is discussed by citing the data of geologic history and hydrometeor. The result shows that global climate change is continuing and the main motive force causing climate change is nature itself but not mankind; the current stage of climate change is a fluctuation part of whole stage of climate change and the change tendency is not eternality; the scope of the current stage of climate change is not exceeding the one of historical climate change. According to the points mentioned above, it may be concluded that the artificial emission of CO₂ is not the main factor causing global climate change. So it is reasonable to analyze and treat particular climate change problem with special measure in the condition of different space-time.Finally some suggestions on dealing with the problem of climate change about China are proposed.
