The implications for climate sensitivity of AR5 forcing and heat uptake estimates

A guest post by Nic Lewis When the Lewis & Crok report “A Sensitive Matter” about climate sensitivity in the IPCC Fifth Assessment Working Group 1 report (AR5) was published by the GWPF in March, various people criticised it for not being peer-reviewed. But peer review is for research papers, not for lengthy, wide-ranging review […]

Kevin O’Neill’s “Fraud” Allegations

Over the past year or so, Mann’s “ClimateBall” defenders have taken an increasing interest in trying to vindicate Mannian principal components, the flaws of which Mann himself has never admitted.  Indeed, in Mann’s self-serving Hockey Stick Wars, Mann once again claimed that the defective method was simply an “alternative centering convention”. So far, I’ve taken little […]

Black Tuesday of Climate Science

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 […]

Inventory of Hide-the-Decline

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 […]

Another Porky from Mann, Williams and Fontaine

Jean S has spotted a highly amusing entry in Mann’s CV. The entry yields yet another porky in Mann’s pleadings.

The Original Hide-the-Decline

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 […]

Mann’s New Memorandum

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 […]

Who Wrote EPA’s “Myths vs Facts”?

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 […]

Mannomatic smoothing: technical details

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 […]
