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.

CPO-funded study shows human-caused boost to drying in Americas, Africa, and Asia

“There has always been natural variability in drought events around the world, but our research shows the clear human influence on drying, specifically from anthropogenic aerosols, carbon dioxide, and other greenhouse gases,” said lead author Felicia Chiang from the University of California, Irvine.

Tackling the challenges of a drier, hotter, more fire-prone future

In a new EOS Opinion Article, MAPP Drought Task Force leaders Rong Fu, Andrew Hoell, Justin Mankin, and Isla Simpson, working with NIDIS staff member Amanda Sheffield, describe the disastrous impacts droughts, heat waves and fires have globally. They also highlight new MAPP- and NIDIS-funded research that tackles the challenges of a drier, hotter, more fire-prone future.
Drought Task Force Provides Rapid Response to Worst U.S. Drought Since 2013 26 January 2021

Drought Task Force Provides Rapid Response to Worst U.S. Drought Since 2013

The Drought Task Force’s rapid response will help us understand the ongoing drought’s causes, how our science is helping us understand the drought, to what extent climate change is playing a role, and how the event may evolve.

Study Provides New Understanding of Plants, Droughts, and Climate Change to Improve Models 12 January 2021

Study Provides New Understanding of Plants, Droughts, and Climate Change to Improve Models

Building models that can appropriately capture plant-water interactions is critical in order to accurately simulate the onset and evolution of droughts and their cascading impacts throughout the Earth system.
