Raymond S. "Ray" Bradley is a climatologist and University Distinguished Professor in the Department of Geosciences at the University of Massachusetts Amherst, where he is also research director of the Climate System Research Center. Bradley's work indicates that the warming of Earth's climate system in the twentieth century is inexplicable via natural mechanisms.

Biography

Bradley was a contributing author to the IPCC TAR. Bradley worked on reconstructing the temperature record of the past 1000 years with Michael E. Mann and Malcolm K. Hughes, an eminent dendrologist. This work (for which is he is publicly best known, although scientifically his contributions to assembling surface temperature records are only rivaled by Phil Jones) figured prominently in the IPCC TAR SPM. In 2005, the Chair of the US House of Representatives Committee on Energy and Commerce, Rep. Joe Barton (R-Texas) demanded that Bradley provide a detailed accounting of the data and funding of his research on climate change. Barton specifically asked for responses to various allegations made by Stephen McIntyre and Ross McKitrick about the Mann, Bradley and Hughes papers. In Bradley's response, he finds the assertions of McIntyre and McKitrick to be without worth, and recommends a commentary by Gavin Schmidt on the RealClimate website (Gavin Schmidt. "Dummies guide to the latest "Hockey Stick" controversy".) as providing a very good guide to the issues.

Interests and activities

Bradley's interests include climate variability and change. Bradley is a member of the RealClimate blog. Bradley has contributed to the public discussion of global warming; in 2002 he was interviewed by CNN on the "melting glaciers of Kilimanjaro" story.
