Water Cycle Extremes: Droughts and Pluvials 

In a study of 20 years of data from the NASA/German GRACE and GRACE-FO satellites, two NASA scientists confirmed that major droughts and pluvials — periods of excessive precipitation and water storage on the landscape — have been occurring more often. They also found that the worldwide intensity of these extreme wet and dry events – a metric that combines extent, duration, and severity — is closely linked to global warming. Floods and droughts account for more than 20% of the economic losses caused by extreme weather events in the U.S. each year, ranked second after hurricanes among major disasters.
