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 […]

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 […]

Nature-mag Hides the Decline

Earlier this year, David Whitehouse of GWPF drew attention to a striking decrease in the UK Met Office decadal temperature forecast, that had been quietly changed by the Met Office on Christmas Eve. Whitehouse’s article led to some contemporary interest in Met Office decadal forecasts. The Met Office responded (see here); Whitehouse was also challenged […]

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 […]

Peer Review of Enhanced Hide-the-Decline

During the counter-attack on Soon et al 2003, Climategate participants made serious allegations about the integrity of its peer review and the editor (Chris de Freitas) who had supervised its publication. (These allegations were investigated by the publisher of Climate Research, Otto Kinne, who cleared de Freitas in unequivocal terms – a finding that did […]

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 […]

Severinghaus and “Hide the Decline”

One of the very first contributions to realclimate was an FAQ from Jeff Severighaus on Dec 3, 2004. A year earlier, Severinghaus attempted (unsuccessfully) to get an explanation of the “divergence” problem from Mann and the rest of the Team. Severinghaus had become interested in the question following a presentation by Tom Karl of NOAA […]

Yamal and Hide-the-Decline

In The Climate Files, Fred Pearce wrote: When I phoned Jones on the day the emails were published online and asked him what he thought was behind it, he said” It’s about Yamal, I think”. Pearce continued (p 53): The word turns up in 100 separate emails, more than ‘hockey stick’ or any other totem […]

Hide the Decline: Sciencemag # 3

The day before yesterday, I reported that Briffa and Osborn (Science 1999) had not just deleted the post=1960 decline (see also CA here), but had deleted the pre-1550 portion as well – the deletions contributing to an unwarranted rhetorical impression of consistency between the reconstructions, an impression that was capitalized upon in the commentary in […]
