Abstract
This article reviews recent literature on drought of the last millennium, followed by an update on global aridity changes from 1950 to 2008. Projected future aridity is presented based on recent studies and our analysis of model simulations. Dry periods lasting for years to decades have occurred many times during the last millennium over, for example, North America, West Africa, and East Asia. These droughts were likely triggered by anomalous tropical sea surface temperatures (SSTs), with La Niña‐like SST anomalies leading to drought in North America, and El‐Niño‐like SSTs causing drought in East China. Over Africa, the southward shift of the warmest SSTs in the...
