Climate Threatens Food Supplies Even With Adaption, with Andrew Hultgren

In this Climate Chat episode, We interview Andrew Hultgren about his recent paper in the journal Nature, "Impacts of climate change on global agriculture accounting for adaptation." The paper concludes that there will be significant drops in agriculture productivity under global warming even with adaption measures. Surprisingly, negative impacts are larger in developed countries with advanced agriculture practices. Andrew Hultgren is an environmental and Industrial Organization economist studying the economics of environmental regulation. His research interests include firm behavior under regulatory uncertainty and quantifying the economic impacts of climate change. ​ Andrew is an assistant professor at the department of Agricultural and Consumer Economics at the University of Illinios Urbana-Champaign, a faculty affiliate at the National Center for Supercomputing Applications, and a member of the Climate Impact Lab.
