Obama’s claim about record droughts similarly fails even on a cursory level – the United States has in all academic estimates been getting wetter over the century (with the 1930’s “dust bowl” setting the drought high point). This is even true globally over the past half-century, as one of the most recent scientific studies of actual soil moisture shows: “there is an overall small wetting trend in global soil moisture.”
奥巴马所声称的出现创记录的旱情，是同样地错误，甚至错在知识浅薄的层次上 – 根据所有的学术估算，美国在一个世纪中已经变得越来越多雨（将1930年代的“尘碗”设置为干旱高点） 。即使在全球范围内，这种情况在过去的半个世纪中也是如此，就如最近的一项针对实际土壤湿度的科学研究所显示的那样： “全球范围内的土壤水分的总体趋势是小幅度上升了。 ”
