Drying of the American West
Part D: Is Drought Here to Stay?
Climate patterns in the Western United States have clearly changed. Water managers are wondering how long this new pattern will continue, and what it means for the Southwest's long-term future. Some scientists predict that the west may be entering a period of persistent drought with climate conditions similar to those that resulted in "megadroughts" during the medieval period. Extended droughts that lasted several decades are thought to be responsible for the migration of indigenous groups out of the area.
