Bayon et al. (Reports, 9 March 2012, p. 1219) interpreted unusually high aluminum-potassium ratio values in an Atlantic sediment core as indicating anthropogenic deforestation around 2500 years before the present (B.P.). We argue that there is no terrestrial evidence for forest destruction by humans and that the third millennium B.P. rainforest crisis can be clearly attributed mostly to climatic change.
Bayon 等人(报告,2012 年 3 月 9 日,第 1219 页)将大西洋沉积物核心中异常高的铝钾比值解释为表明在当前之前约 2500 年前人类对森林的砍伐。我们认为,没有人类破坏森林的陆地证据,并且可以明确地将公元前第三千年的雨林危机主要归因于气候变化。
