"Brian O'Neill leads the Integrated Assessment Modeling (IAM) group within the Terrestrial Sciences Section at NCAR. He also leads NCAR's Climate and Human Systems Project, and co-chairs the Societal Dimensions Working Group of NCAR's climate model, the Community Earth System Model (CESM).
Brian holds a Ph.D. in Earth Systems Science and an M.S. in Applied Science, both from New York University, and has worked previously on the science staff of the Environmental Defense Fund in New York, and as an Assistant and Associate Professor (Research) at Brown University's Watson Institute for International Studies. During the period 2005-2009, he founded and led the Population and Climate Change Program at the International Institute for Applied Systems Analysis (IIASA) in Austria.
His research interests are in the the relationship between future societal development, emissions, and climate change impacts. Research approaches include the development of long-term scenarios, linking of models of the climate system with those of human systems, and the incorporation of uncertainty in analyses of climate-related decisions.
Brian is the lead author (along with Landis MacKellar and Wolfgang Lutz) of Population and Climate Change, published by Cambridge University Press. He has also served as a lead author for the Intergovernmental Panel on Climate Change's Fourth and Fifth Assessment Reports in a volume on impacts, adaptation and vulnerability (Working Group II), and for the Millennium Ecosystem Assessment (MA) in a volume on Scenarios."
