Edward Wegman
There has been renewed interest in the Wegman Report, which purported to critique the work of paleoclimatolgists Michael Mann, Raymond Bradley and Malcolm Hughes and their controversial “hockey stick” millennial temperature reconstruction.
Today we’ll take a closer look at Wegman et al’s key passage on tree-ring proxies and do a detailed side-by-side comparison with its apparent main antecedent, chapter section 10.2 in Raymond Bradley’s classic Paleoclimatology: Reconstructing Climates of the Quaternary.
That comparison leaves no doubt that Wegman et al’s explication was substantially derived from that of Bradley, although the relevant attribution appears to be missing. There are, however, several divergences of note, also in the main unattributed, and some of Wegman’s paraphrasing introduces errors of analysis.
But the real shocker comes in two key passages in Wegman et al, which state unsubstantiated findings in flagrant contradiction with those of Bradley, apparently in order to denigrate the value of tree-ring derived temperature reconstructions.
According to TimesOnline, investigators of the CRU email theft (dubbed SwiftHack or Climategate) have concluded that the release of the stolen material was held back for weeks in order to cause maximum damage to the upcoming Copenhagen conference.
Here is the first of an occasional series that will look back at the origins of various major players among Canada’s climate contrarians. And, quite appropriately, the honour of inauguration belongs to none other than our old, um, acquaintances, Friends of Science.
