David Wahl
David is a research scientist at the Geology, Minerals, Energy, and Geophysics Science Center. He received a PhD in Geography from UC Berkeley in 2005. Since joining the USGS in 2004, he has worked to understand drivers and impacts of Quaternary environmental change in North America. Now, his research focuses on reconstructing climate and anthropogenic environmental change.
Biography
After coming to the Menlo Park office of GMEG In 2004, David is currently focused on reconstructing climate and anthropogenic environmental change in the western US, Guatemala, and the central Pacific.

Status: Active Drivers and Impacts of North Pacific Climate Variability
Climate model forecasts indicate an increase in extreme hydrologic events, including floods and droughts, for California and the western U.S. in the future. To better understand what the consequences of this future change in climate may be, USGS scientists are studying the frequency, magnitude, and impacts of past hydroclimate variability and extremes in the region. This project produces well-...
