Sixty years of climate change warnings: the signs that were missed (and ignored) 60年来的气候变化警告：那些被错过（和忽视）的迹象 The effects of ‘weird weather’ were already being felt in the 1960s, but scientists linking fossil fuels with climate change were dismissed as prophets of doom 在20世纪60年代，人们已经感受到了 “异常天气”的影响，但将化石燃料与气候变化联系起来的科学家却被视为厄运的预言家。 In August 1974, the CIA produced a study on “climatological research as it pertains to intelligence problems”. 1974年8月，中央情报局制作了一份关于“与情报问题有关的气候学研究”的研究。 The diagnosis was dramatic. 该研究所下的结论是非常戏剧性的。 It warned of the emergence of a new era of weird weather, leading to political unrest and mass migration (which, in turn, would cause more unrest). 它警告说，一个新的异常天气时代的出现，将导致政治动荡和大规模移民（反过来，这又会导致更多的动荡）。 The new era the agency imagined wasn’t necessarily one of hotter temperatures; the CIA had heard from scientists warning of global cooling as well as warming. 该机构想象的新时代不一定是温度升高的时代；中情局从科学家那里听到了全球降温和升温的警告。
