The term was first used by Connie Woodhouse and Jonathan Overpeck in their 1998 paper, 2000 Years of Drought Variability in the Central United States. [2] [3] In this, it referred to two periods of severe drought in the US – one at the end of the 13th century and the other in the middle of the 16th century. [3]
Since 2000, climate change has been the primary cause of both the expansion of the drought area and the increase in drought severity, with that percentage rising to over 90% during the drought period.
The drought is largely driven by temperature, which increases the rate of evaporation, with some contribution from the lack of precipitation. The several wet years since 2000 were not sufficient to end the drought. Researchers calculated that without climate change-induced evaporation, the precipitation in 2005 would have broken the drought.
