A new NASA study says that global warming may increase the risk for extreme rainfall and drought, according to a news release from the space agency. This is the first study to demonstrate how increasing carbon dioxide concentrations could impact the entire range of rainfall types on our planet.
Examination of computer simulations from 14 climate models suggests that wet regions of the world will experience increases in extreme rainfall due to warming resulting from projected increases in carbon dioxide levels. Dry areas and regions with moderate rainfall, however, could be become drier.
