二氧化碳是主要的温室气体。全球能源消耗随世界经济增长而上升,燃烧煤、石油和天然气等化石能源排出绝大部分的二氧化碳。因此,长此以往大气中的二氧化碳将达到危险含量。

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend.
