NASA: Warming-Driven Changes in Global Rainfall


By Kathryn Hansen NASA Goddard Space Flight Center. A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought.

Model simulations spanning 140 years show that warming from carbon dioxide will change the frequency that regions around the planet receive no rain (brown), moderate rain (tan), and very heavy rain (blue). The occurrence of no rain and heavy rain will increase, while moderate rainfall will decrease.
