The Hockey Stick and the Climate Wars: Dispatches from the Front Lines

Michael Mann

Tuesday, May 7, 2013 at 7:30 p.m. at the Virginia Air and Space Center in downtown Hampton, Virginia. FREE (no reservations).

Abstract

A central figure in the controversy over human-caused climate change has been “The Hockey Stick,” a simple, easy-to-understand graph Dr. Mann and colleagues constructed to depict changes in Earth’s temperature back to 1000 AD. The graph was featured in the high-profile “Summary for Policy Makers” of the 2001 report of the Intergovernmental Panel on Climate Change (IPCC), and it quickly became an icon in the debate over human-caused (“anthropogenic”) climate change. Dr. Mann will tell the story behind the Hockey Stick, using it as a vehicle for exploring broader issues regarding the role of skepticism in science, the uneasy relationship between science and politics, and the dangers that arise when special economic interests attempt to skew the discourse over policy-relevant areas of science.
