A new report by the Obama administration says global warming is “unequivocal and primarily human-induced.” The Washington Post reports the study details how climate change will affect certain parts of the United States. In the Northeast, the heaviest rainstorms have become 67 percent heavier since 1958, as warmer weather evaporates more water vapor into the atmosphere to feed storm clouds. Around the Great Lakes, snowstorms could get heavier as ice recedes and exposes more open water. By 2100, parts of the South could experience 150 days a year with temperatures higher than ninety degrees.
