Climate Choice: Reducing Emissions Can Help the Southwestern U.S. Avoid Megadrought Disaster

  • A 2015 NASA study finds that unabated global greenhouse gas emissions will increase the risk of a 30-year long "megadrought" in the Southwestern U.S.

  • Megadrought likelihood is on pace to increase from the current 12% to 80% by 2100.

  • Reducing global emissions can lower this risk to 60% or less.
