A global increase of extreme precipitation, well outside the range of natural variability, has been well-documented by scientists. It’s one of the hallmarks of human-caused global warming, and new research published this week in Nature shows that high-elevation areas, including most of the mountains of Western North America, are particularly vulnerable to deluges that can trigger landslides, floods and severe erosion. The research by the Department of Energy’s Lawrence Berkeley National Laboratory focused on rainfall extremes, “owing to their instantaneous triggering of runoff and association with floods, landslides and soil erosion,” the authors wrote.
