Study: Dry future likely unavoidable for Southwest, but reducing greenhouse gases can still help
For the past two decades, the southwestern United States has been desiccated by one of the most severe long-term droughts—or ‘megadroughts’—of the last 1,200 years. And now, scientists say the risk of similar extreme megadroughts and severe single-year droughts will increase in the future as Earth’s temperature continues to rise, according to a new study in Earth’s Future sponsored by CPO’s Modeling, Analysis, Predictions, and Projections (MAPP) program and led by NASA’s Goddard Institute for Space Studies (GISS).
