Lewandowsky and “Hide the Decline”

Ethics bait-and-switcher Stephan Lewandowsky and his sidekick, Klaus Oberauer, have added hide the decline to their repertoire at the University of Western Australia blog. As CA readers are well aware, the Briffa et al 2001 reconstruction, based on 387 tree ring density chronologies, goes down in the latter part of the 20th century – clearly […]

Myles Allen and a New Trick to Hide-the-Decline

Myles Allen has written here blaming Bishop Hill for “keeping the public focussed on irrelevancies” like the Hockey Stick: My fear is that by keeping the public focussed on irrelevancies, you are excluding them from the discussion of what we should do about climate change But it’s not Bishop Hill that Myles Allen should be […]

Hide-the-Decline Plus

A few days ago, we discussed the unresponsive answers provided to climate scientist Jeff Severinghaus in February 2003 when he inquired about the validity of tree ring widths as proxies due to the inconsistency (divergence) between temperature and ring widths, answers characterized by Severinghaus here as not being a “straight answer”. In first quarter 2003 […]

Still Hiding the Decline

Even in their Nov 24, 2009 statement, the University of East Anglia failed to come clean about the amount of decline that was hidden. The graphic in their statement continued to “hide the decline” in the Briffa reconstruction by deleting adverse results in the last part of the 20th century. This is what Gavin Schmidt […]

Gergis and Law Dome

In today’s post, I’m going to examine Gergis’ dubious screening out of the Law Dome d18O series, a series that has been of long-standing interest at Climate Audit (tag). Gergis et al 2016 stated that they screened proxies according to significance of the correlation to local gridcell temperature. Law Dome d18O not only had a significant […]

Antarctic Ice Mass Controversies

Like many others, I was interested in the recent controversy arising from findings of Zwally et al 2015 that there had been ice mass gain gain of ~112±61 Gt/year over 1992-2001 and ~82±25 Gt/year over 2003-2008.  Zwally’s findings obviously contradict a widely held contrary belief, expressed, for example, in IPCC AR5’s assertion there was “high confidence” that the […]

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 […]

Oral Argument 1: Context

I have an audio copy of the oral argument in Mann v Steyn, which I’ve posted up (see link at the end of this post). One of things often under-estimated by those readers (especially at WUWT) who are bloodthirsty for litigation as a means of settling scores is that it’s not easy for litigation lawyers to […]

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 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 […]
