地质时期的CO2及其温室效应

本文对当前流行的人类活动导致CO_2增加使未来气候变暖的温室效应的说法提出质疑,研究表明,自大气圈形成以来,CO_2已由原始大气主要成分(91％)波动下降到现在的微量组分(0.034％),其演化过程主要受自热因素控制,当前CO_2浓度增加是人为因素与自然作用叠加的结果,并不一定是人类活动或工业革命的产物,与此同时已经证实,冰期降温不是因为CO_2减少、温室效应减弱,而近年CO_2增加,温室效应加强又未得到确证,因此,以未来人为活动导致的CO_2变化趋势预测气候变化及可能的环境影响还为时尚早。

CO2 throughout Geologic Time and Its Green-house Effects

This paper queries the problem whether global climate warming in the future is doe to the increase of carbon dioxide by human activities as it is said prevai lingly. The authors suggest that in view of CO₂ throug-kout geologic time, CO₂ component in the atmosphere has decreased from 91% primarily to 0.034% currently since formation of the atmosphere, nevertheless the present fluctuation of CO₂ would be the aggregate results of human activities and natural action both, not of humaa activities only. So, prediction of global warming based on CO₂ greenhouse effect it not of sufficient evidence according to the authors.
