单选题 Cet-6-1.16-Exercise 02 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. But the United Nations climate panel's latest assessment tells us precisely the opposite. For "North America there is medium confidence that there has an overall slight tendency toward less dryness". Moreover, there is no way that Krugman could have identified this drought as being caused by global warming without a time machine; climate models estimate that such detection will be possible by 2048, at the earliest. What is the author's comment on Krugman's claim about the current drought in America's Midwest

A. It will eventually get proof in 2048

B. It focuses on theory rather than on practical skills

C. There is no way to prove its validity

D. There is no essential difference between seemingly opposite opinions
