Michael F. Wehner’s current research concerns the behavior of extreme weather events in a changing climate, especially heat waves, intense precipitation, drought and tropical cyclones. Before joining the Berkeley Lab in 2002, Wehner began his career as a nuclear weapons physicist at the Lawrence Livermore National Laboratory before joining the Program for Climate Modeling Diagnosis and Intercomparison.

He is the author or co-author of over 75 scientific papers. He was also a member of the lead author team for the 2009 White House report, “Global Climate Change Impacts in the United States” and has been selected as a lead author for the upcoming Fifth Assessment Report of the Intergovernmental Panel on Climate Change.
