New study shows global warming intensifying extreme rainstorms over North America
The likelihood of intense storms is rising rapidly in North America, and the study, published Monday in the Proceedings of the National Academy of Sciences, projects big increases in such deluges. … If the current rate of warming continues, Earth will heat up 5.4 degrees by 2100. Then, 20, 50 and 100-year extreme rainstorms could happen every 1.5 to 2.5 years, the researchers concluded.
