Climate models predict that as global temperatures rise over the next seven decades, subtropical regions like the American Southwest will get drier, while more northern areas, including much of Canada, will get wetter. But for the rest of North America the 2080 water forecast is mixed. The Northeast and the Pacific Northwest may see only a slight increase in annual precipitation, maybe one or two percent, but storms are likely to become more intense. Seasonal variation is likely to increase as well, leading to wetter winters and drier summers that could disrupt local water supplies.
