Via Richard Klein's Twitter feed comes this interview with Raymond Bradley in which he discusses his new book. Fascinating stuff, particularly this bit:
In 1998, a post-doc, Mike Mann, Malcolm Hughes and I published an article in Nature on climate in the last 600 years (Mann et al. 1998). Then, in 1999, we published another article in Geophysical Research Letters on temperature over the last 1000 years (Mann et al. 1999). The title was “Northern hemisphere temperatures during the past millennium: inferences, uncertainties, and limitations.” We were emphasising the uncertain nature of the problem. But nevertheless, when it got picked up by the summary for policymakers of the third Intergovernmental Panel on Climate Change (IPCC) report, important caveats were left out.
