CCR IAM Staff: Brian O'Neill, Scientist III
Brian O'Neill leads the Integrated Assessment Modeling (IAM) group within the Climate Change Research section at NCAR. The IAM group is also part of NCAR's Integrated Science Program (ISP). 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 field of integrated assessment modeling of climate change, which links socio-economic and natural science elements of the climate change issue in order to address applied, policy-relevant questions. Current areas of focus include the relationship between socio-economic development pathways, emissions, and climate change impacts, and scenario analyses linking long-term climate change goals to shorter-term actions.
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 Assessment Report in a volume on impacts, adaptation and vulnerability (Working Group II), and for the Millennium Ecosystem Assessment (MA) in a volume on Scenarios. He is currently serving as lead author in the IPCC's Fifth Assessment Report, in Working Group II.
