Ray Bradley
Encyclopedia
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.

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 as providing a very good guide to the issues.

Temperature record of the past 1000 years
The temperature record of the 2nd millennium describes the reconstruction of temperatures since 1000 CE on the Northern Hemisphere, later extended back to 1 CE and also to cover the southern hemisphere. A reconstruction is needed because a reliable surface temperature record exists only since about...
