Uncertainty in Climate Change: A Conversation with Climate Scientists and Economists

Thursday, November 21, 2013 - 9:00am

Bill Nordhaus (Yale), Marty Weitzman (Harvard), Gary Yohe (Wesleyan), John Reilly (MIT), Tony Smith (Yale), Geoff Heal (Columbia), Mark Pagani (Yale), Dan Lunt (U. of Bristol), Chris Forest (Penn State), Trude Storelvmo (Yale), Klaus Keller (Penn State), Kevin Trenbert (NCAR), Bill Boos (Yale), Stephen Schwartz (Brookhaven Nat. Laboratory) were the climate scientists and economists participating in a day-long workshop to discuss the role of uncertainty in climate change and its economic and social impacts.

The workshop, which was jointly sponsored by the center for Sustainable Climate Risk Management at Penn State, was a rare gathering of these two disciplines, and the first since the release of the IPCC’s 5th Assessment Report.  Speakers explored topics such as uncertainty in the climate’s sensitivity to greenhouse gases, the role of aerosols in atmospheric modeling, and the deep statistical issues inherent in projections of global warming from climate models and their implications for economic modeling of climate policies.
