全球变暖会导致气候严寒吗

文章对美国国防部“秘密报告”中全球变暖可能导致严寒的理论根据和现实可能性作了分析,指出由于气候变暖、极冰融化影响大洋的环流,进而影响全球气候;这样的事件在历史上曾有多次发生。但目前还不能说已经开始发生这样的过程。而且没有这样的先兆。因此,到2020年,发生“秘密报告”中所提出来的情景的可能性很小,但是不排除在更长时间发生某种气候受变的可能性,所以加强对气候突变的研究是非常必要的。

WILL THE GLOBAL WARMING BRING CHILLING

An analysis on the Report of OSD (Office of Security Department) is made. The report suggests that gradual global warming will bring chilling. It is indicated that the chilling had occurred many times in the past, for the warming melt ice cover, modulated the thermohaline circulation, and finally influenced on the global climate. However, it is premature to say that a new phase of chilling is coming, because no strong precursor has been found. Therefore, in the near future occurrence of the scenario suggests in the report is almost impossible. But it is difficult to exclude the possibility of occurrence of a chilling in some whatlonger time, so it is necessary to increase the research on the abrupt climate change.
