Today I will review the timeline of the above WMO 1999 graph in the light of the ClimateGate (CG) letters. The main events took place on Tuesday, November 16th, 1999. Things start rolling 9 AM (UK time), when Tim Osborn sends the new Briffa and recalibrated Jones (1998) time series to Phil Jones along with […]
In a recent post, I reported on the diagram in Jones 1998 (Science), which pushed hide-the-decline a year earlier than my previous inventory. (The Briffa bodge, an earlier technique, dates back to 1992 and Jones 1998 is a sort-of transition from the Briffa bodge to truncation as hide-the-decline technology.) I’ve had a few requests for […]
Jean S has spotted a highly amusing entry in Mann’s CV. The entry yields yet another porky in Mann’s pleadings.
In a twitter exchange among Jean S, Ronan Connolley and Tim Osborn, Ronan drew attention to an early spaghetti graph in a comment on MBH98 published by Phil Jones in Science on the day after (Apr 24, 1998) publication of Mann et al 1998. The Briffa reconstruction is in purple below. Like IPCC 2001, it […]
Michael Mann’s reply brief in the Court of Appeals has been posted here. Its main points are very similar to their reply memoranda of January 2013 (to CEI; near identical to NR) Some comments have been accumulating on an unrelated topic. Please comment on this thread. I’ll try to write something over the next couple […]
PCA was also performed on certain proxy sub-networks (spatially dense regional networks of tree-ring data available separately in different continents) as means of dimensional reduction of the predictor network. In this case, the procedure was performed separately for each independent step of the stepwise calibration/reconstruction procedure described in “3” below. A decreasing number of PCs […]
The Mann Statement of Claim prominently displayed, as one of only two quotations from the “inquiries”, an extended quotation from the Myths vs Facts webpage, included as one of three Resources accompanying the EPA decision denying reconsideration of various petitions for reconsideration of the Endangerment Finding (though Mann’s Statement of Claim falsely cited the gazetted […]
This post is rather technical, and it is intended mainly for the historical completeness. So unless you are very, very interested in the tiny technical details of the HS saga, you can safely skip this. As most readers are aware, and stated in my post few hours after CG broke out, Mike’s Nature trick was […]
Jean S writes (transferred from a comment with the addition of a few headings): A question for the experts: is it known who wrote and who were used as experts in the EPA documents? If not, is that information considered public (i.e., obtainable under FOIA or similar)? The reason I ask is that I get […]
In a recent post, I observed that Mann’s Statement of Claim contained a bizarre misrepresentation about the nature of Mann’s research, as it falsely credited Mann with being “one of the first” to document the increase in 20th century temperatures. Reader PhilH, a retired judge, observed that, on its own, the misrepresentation was merely odd and that […]
