Gary W. Yohe is the Woodhouse/Sysco Professor of Economics at Wesleyan University. He has published more than 100 articles that have focused attention on both the mitigation and adaptation/impacts sides of the climate issue. This work has led him to visualize both policies as tools with which to try to manage the risk of climate change in an uncertain world. He served as a Lead Author for four different chapters in the Third Assessment Report of the Intergovernmental Panel on Climate. More recently, Dr. Yohe served as Convening Lead Author for one chapter in the Response Options Technical Volume of the Millennium Ecosystem Assessment and is currently serving as Convening Lead Author for Chapter 20 of the Working Group II contribution to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change; there, the focus is on bringing perspectives of sustainable development to the discussion of adaptation and mitigation in the face of climate-induced risk. Dr. Yohe also recently served as one of five editors of Avoiding Dangerous Climate Change.
