Influence of Anthropogenic Climate Change on Planetary Wave Resonance and Extreme Weather Events

Michael E. Mann, distinguished professor of atmospheric science at Penn State University, completed research with Stefan Rahmstorf, Kai Kornhuber and Dim Coumou to demonstrate a direct link between climate change and a large family of extreme recent weather events. 

The researchers looked at historical atmospheric observations and nearly 50 climate models to discover how these large-scale climate events evolve over time. They are now able to connect human-caused global warming to an array of extreme recent weather events. 

Also working on this project was Sonya K. Miller, programmer analyst at Penn State; and Byron A. Steinman, assistant professor from the Department of Earth and Environmental Sciences and Large Lakes Observatory in the University of Minnesota: Duluth.
