Michael Glotter will be presenting, "Evaluating the Utility of Regional Climate Models in Agricultural Impacts Projections."

One of the largest concerns about future climate change is its potential effect on food supply. Crop yield projections require climate inputs at higher resolution than typical for global climate models, and the computationally expensive technique of dynamical downscaling is widely used for this translation. We simulate maize in the U.S. to test whether current dynamical downscaling methods add value over simpler downscaling approaches. Our results suggest that they do not. Addressing large-scale systematic biases in climate output may be a higher priority for under- standing future climate change impacts.
