From Climate Change Will Bring Wetter Storms in U.S., Study Says, in the New York Times [2016-12-06]  

Decades of research (and perhaps your own recent experiences on hot, humid days) have suggested that climate change will lead to an increase in big storms that cause flash floods, landslides and other natural disasters. Now, a new study shows that such intense precipitation will most likely increase across the continental United States, but with important regional variations.

The study by scientists from the National Center for Atmospheric Research in Boulder, Colo., published on Monday in Nature Climate Change, found that across the country, rainstorms may become more frequent and intense if greenhouse gas emissions remain at current levels. The biggest increase would be in the Northeast and the Gulf Coast.

In fact, the study shows that these intense storms could become five times as frequent. And when they do happen, there could be up to 70 percent more rain, potentially turning a heavy but not catastrophic storm into something closer to a biblical flood. …

Climate scientists had anticipated these results and have already seen some of them play out, with serious flooding in New England and Louisiana over the last several years. But this study provides a new layer of detail and analysis, said Kevin E. Trenberth, a senior researcher at the National Center for Atmospheric Research who was not involved in it.
