对气候变暖问题争议的分析
综合评述和分析了近年来关于全球气候变暖问题的研究。重点是有关气候变暖的一些争议。目前的结论是:(1)19世纪中期以来全球平均地表气温上升了0.4~0.8℃;(2)全球气候变暖的论断得到了海洋温度、大气温度、钻孔温度、陆地雪盖、海冰及冰川资料的支持;(3)1998年是近一个半世纪有观测资料以来最暖的一年,对1961~1990年平均的距平为0.55℃。20世纪变暖的趋势为0.066℃/10a;(4)1990′s是20世纪最暖的10年,平均气温距平0.35℃,也可能是500a 或者甚至1000a来最暖的10年。所以,20世纪气候的变暖是无可怀疑的。人类活动影响很可能是20世纪气候变暖的主要原因,至少...
