众多网站、博客以及媒体文章宣称气候不再变暖,而是正在变冷。在此我们表明,在观测记录的过去34年中,以及在受温室气体增加驱动的20世纪和21世纪的气候模型模拟中,都发现了全球平均地表气温无趋势甚至变冷的时期。我们表明,在21世纪的气候可能而且很可能会出现这样的情况:在存在长期变暖趋势的情况下,全球平均地表气温会出现十年或二十年没有趋势甚至轻微变冷的时期。引用:伊斯特林,D. R.,和M. F. 韦纳(2009年),气候是在变暖还是变冷?《地球物理学研究快报》,36卷,L08706,doi:10.1029/2009GL037810
Numerous websites, blogs and articles in the media have claimed that the climate is no longer warming, and is now cooling. Here we show that periods of no trend or even cooling of the globally averaged surface air temperature are found in the last 34 years of the observed record, and in climate model simulations of the 20(th) and 21(st) century forced with increasing greenhouse gases. We show that the climate over the 21(st) century can and likely will produce periods of a decade or two where the globally averaged surface air temperature shows no trend or even slight cooling in the presence of longer-term warming.
