介绍了各种古气候代用指标所反映的地球地质时期以来的气候变化．结果表明：气候的冷暖变化在整个地球演化历史过程中都是存在的；地球历史上气候变化的速率快、幅度大；在人类活动大量产生温室气体之前，地球气温就在不断地升降，表明这是自然周期所致；近千年来气温与温室气体排放量没有完全对应关系．毫无疑问当今全球变化仍会受到自然周期的影响，一味强调人类活动致暖可能是片面的．

Climate change during the geological time of the earth as reflected by kinds of paleoclimate indicators was introduced. The results show that, climate has kept changing during the whole evolution history of the earth. And the climate changed rapidly and largely in the past. Climate change occurring prior to abundant greenhouse gas was re- leased by human activity, which indicates that natural period was responsible to climate change during the earth histo- ry. There is no exact correspondence between the temperature and discharge of greenhouse gas during the latest thou- sand years. It is no doubt that today＇s glaobal change is still influenced by natural period. It is one -sided to em- phasize solely that human activiies cause global warming.
