Several American Geophysical Union scientists are available to comment on the science of droughts and their possible impacts throughout the summer drought season, including effects of ancient megadroughts and how climate change will affect drought severity and risk in the coming decades.

Amir AghaKouchak is an Associate Professor of Civil and Environmental Engineering at the University of California, Irvine. His research focuses on natural hazards and climate extremes (droughts, floods, heatwaves) and crosses the boundaries between hydrology, climatology and remote sensing.

Julio Betancourt is a Senior Scientist with the U.S. Geological Survey in Reston, Virginia. His expertise is on the influence of climate variability on physical and biological systems at seasonal to millennial timescales. He works to understand and forecast landscape change in response to climate variability and to develop rational approaches to managing water and other natural resources under an uncertain and changing climate.
