Research Interests & Background

Professor Overpeck (“Peck”) is a climate scientist who has written over 200 papers on climate and the environmental sciences, served as a Coordinating Lead Author for the Nobel Prize winning IPCC 4th Assessment (2007), and also as a Lead Author for the IPCC 5th Assessment (2014). Other awards include the US Dept. of Commerce Gold Medal, a Guggenheim Fellowship, the Walter Orr Roberts award of the American Meteorological Society, and the Quivira Coalition’s Radical Center Award for his work with rural ranchers and land managers. Peck has active climate research programs on five continents, loves trying to understand drought and megadrought dynamics (and risk) the world over. He has appeared and testified before Congress multiple times, is a Fellow of the AAAS and AGU, and tweets about climate-related issues (@GreatLakesPeck).
