Scott Weaver

Senior Climate Scientist


Areas of expertise: Global and regional climate variability and change, extreme climate events, hydrologic cycle.

Scott Weaver leads the climate science team at EDF. The team conducts, assesses, and communicates climate science research to support the scientific foundation for cross programmatic activities and policy development.


Prior to joining EDF, Scott was a lead climate scientist for the National Oceanic and Atmospheric Administration (NOAA) where he led scientific research aimed at improved understanding of U.S. hydroclimate variability and change with a focus on the climatic context for extreme events, including the regional variability of droughts, floods, and severe weather. Scott holds an appointment as an Associate Adjunct Professor in the Department of Atmospheric and Oceanic Science at the University of Maryland and is the recipient of the 2012 Presidential Early Career Award for Scientists and Engineers (PECASE).
