摘要: It has long been believed that the 20th warming was preceded by "Little Ice Age" and "Medieval Warm Period" as a result of natural variability climate. But [Bradley][1] explains in this Perspective, recent research shown these climate patterns may not have global, are much more variable time space than previously assumed. However, one fact remains indisputable, namely end-20th century temperatures were higher at any during last millenium. [1]: http://www.sciencemag.org/cgi/content/full/288/5470/1353
