Sagan and his co-author George Mullen hypothesized that carbon dioxide (CO2) concentrations were much higher during the Archean—possibly 100 times higher than they are today—and therefore the atmosphere could retain enough heat to keep the planet from freezing.

萨根及同事乔治·马伦提出假设：在太古代期间，二氧化碳浓度要高得多——可能比现在高出100倍，因此大气中可能保留了足够的热量，使地球免于冻结。

According to the science report, as the environment pollution comes worse and worse, the discharge of CO2 is increasing, the temperature is increasing too. If it cannot be improved yet, at the middle age of this century, the iceberg and glacier of the Antarctica and the Arctic Pole will melt because of the "greenhouse effect", at that time, the sea level will rise and even submerge the land which we live on!

据科学家报道，由于现在环境污染严重，二氧化碳排放日益增加，地球气温逐年增高，如果还不得到改善，本世纪中叶，气温问题将引起南北极冰川融化，到时海平面会上升，甚至将淹没我们赖以生存的陆地！
