The Great North American Megadrought

The video discusses the severe droughts in California and the potential threat of megadroughts, which are prolonged droughts lasting decades. Historical studies, including those by Overpeck and Woodhouse, have shown that megadroughts have occurred in the past, affecting civilizations and ecosystems. The video explains how droughts form, the role of atmospheric patterns, and the impact of climate change. Future predictions suggest that megadroughts could return, driven by increased evaporation due to global warming. Mitigation strategies include greywater reuse and desalination, though these have challenges.
