Reductio ad mannium

The new article by Rahmstorf and Mann (see RC here) has been criticized at WUWT (here here) for making claims about Atlantic Ocean currents based on proxies, rather than measurements. (Also at Judy’s here)   But it’s worse, much worse than we thought. Rahmstorf and Mann’s results are not based on proxies for Atlantic current velocity, but […]

How Mann tricked Weaver

In today’s post, I’ll show that even Andrew Weaver was tricked by Mann’s IPCC 2001 hide-the-decline. Weaver’s incorrect belief that the IPCC diagram showed “four” “independent” “hockey sticks” constructed using “different techniques” led him to believe that the research was much solider than it really was (or is), to say that our focus on the Mann […]

More Mann Grafting

Jeff Norman draws attention to Figure 1 in a new Mannian tirade, a variation of Mann’s stump speech in which he, as usual, tries to blame his own errors and tricks (the censored directory, verification r2 of 0, upside-down Mann, hide the decline) on right-wing interests.  Amusingly, his new Figure 1 unapologetically splices proxy and […]

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 […]

Misrepresentations and the Tainted Narrative of Mann’s Complaint

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 […]

Mann Misrepresents the EPA – Part 1

In today’s post, I will return to my series on false claims in Mann’s lawsuit about supposed “exonerations”. ( For previous articles, see here). One of the most important misconduct allegations against Mann – the “amputation” of the Briffa reconstruction in IPCC TAR – was discussed recently by Judy Curry, who, in turn, covered Congressional testimony […]

Mann Misrepresents NOAA OIG

In today’s post, I’ll consider a fifth investigation – by the NOAA Office of the Inspector General OIG here- and show that, like the other four considered so far, Mann’s claims that it “investigated” and “exonerated” Mann himself were untrue. In addition, I’ll show that Mann’s pleadings misrepresented the findings of this investigation both through […]

Mann Misrepresents the UK Commons Committee

Mann’s inclusion of the UK House of Commons Science and Technology Committee (“Commons Committee”) among the investigations that supposedly “investigated” and “exonerated” Mann personally is as invalid as his similar claims regarding the Oxburgh and Muir Russell inquiries or his claim to have won a Nobel prize. The Commons Committee (see report here) did not […]
