This web resource is inspired by a grant from the U.S. National Science Foundation (NSF) to explore global drought and megadrought (droughts lasting multiple decades). Our group analyzes both instrumental and paleoclimatic (pre-instrumental) data along with state-of-the-art Earth System Model data, all in a context designed to enable better decision-making with respect to drought. From a science perspective, understanding drought and megadrought requires working at the nexus of climate dynamics, paleoclimatology, climate modeling, and much more. From a decision-maker or resource manager perspective, dealing with drought requires operating at the nexus of politics, economics, energy, water, agriculture and much more. Although we focus on the global impacts of drought, this site also emphasizes the time and space scales that matter most for those thinking about drought. This site goes beyond our NSF project to integrate insights developed with the help of other funding as well. Please explore our website and learn more about drought and megadrought around the globe.
