　　Apparently everyone knows that global warming only makes climate more extreme. A hot, dry summer has caused another flood of such claims. And one of the players that benefit the most from this story is the media: the idea of “extreme” climate simply makes for more exciting news.
　　Consider Paul Krugman writing breathlessly in The New York Times about the “rising incidence of extreme events.” He claims that global warming caused the current drought in America’s Midwest, and that supposedly record-high corn prices could cause a global food crisis(危机)。
　　But the United Nations’s latest assessment tells us precisely the opposite—there has an overall slight tendency toward less dryness in North America. Moreover, there is no way that Krugman could have identified this drought as being caused by global warming without a time machine since climate models estimate that such detection will be possible by 2048, at the earliest.
　　And, fortunately, this year’s drought appears unlikely to cause a food crisis, as global rice and wheat supplies are plentiful. Moreover, Krugman overlooks inflation(通货膨胀)：Prices have increased six-fold since 1969.So, the inflation-adjusted price of corn was higher throughout most of the 1970s.
