Briffa teaches, but will McIntyre ever learn?

Recently we’ve discussed several aspects of the raging controversy around climate blogger Steve McIntyre and dendrochronologist Keith Briffa and the supposed destruction (once again) of the “hockey stick” temperature graph.

A few commentators have suggested that more attention should be paid to  McIntyre’s actual “analysis” of Briffa’s Yamal tree-ring chronology, and less to his outrageous accusations (not to mention all the inconvenient evidence that those accusations were completely without foundation).

Now that Keith Briffa has delivered his promised detailed response in an article co-written with Thomas Melvin, it is a good time to do just that. Here, then, is a review of the various problems I and others have pointed out in comments here and elsewhere over the past while, along with highlights from Briffa’s response.

First, here is the abstract of Briffa’s article .

Let the backpedalling begin

KHantemirovRM Fig 5 zoomThe latest battle over the “hockey stick” has taken quite a turn, one that may finally lay to rest all the  absurd claims of its demise made by contrarians (not to mention apparently libelous accusations of scientific malfeasance). In previous posts, we discussed climate blogger Steve McIntyre’s scurrilous accusations of “cherrypicking” against UK dendrochronolgist Keith Briffa, and summarized a a quick technical critique of McIntyre’s work by a dendrchronologist known as Delayed Oscillator.

Now comes new evidence that McIntyre’s accusations were completely false. And not only that, one of the Russian researchers who actually control the raw tree-ring data that McIntyre was mistakenly hounding Briffa for, has apparently confirmed that utilization of  a newer more complete Yamal data set has no substantial effect  on Briffa’s Yamal temperature reconstruction.

“Delayed Oscillator” on divergence

Anyone who has blogged, or even just hangs around blogs more than they should, is familiar with the “pingback”. You know, it’s that automatically generated comment that signals that another blog has referred to a particular post. Yesterday, I got this “pingback” from a blogger called Delayed Oscillator (or “delayed.oscillator” as it is formatted there) and decided to follow it up.

And am I ever glad I did. DO (pronounced Dee-Oh), as I will call this blogger (I hope that’s OK!) has brought a welcome expert perspective to the discussion of the Steve McIntyre-Keith Briffa controversy, said by certain economists and business section editors to expose the global warming sham once and for all. In a two-part series of posts, DO shows why it “ain’t necessarily so” (to say the least).

Climate “auditor” Steve McIntyre: Yamal like “crack cocaine”

By now, anyone who follows the climate blog wars knows that a new battle is underway over the standard temperature reconstruction popularly known as the “hockey stick”. Although it has been declared thoroughly shattered many times, apparently it must be attacked again and again.

Over the last few days, self-appointed climate “auditor” Steve McIntyre has made several insinuations concerning the work of UK dendro-climatologist Keith Briffa, focusing on the recently released Yamal series of tree-ring measurements. Along the way, he has once again rehashed an oft-repeated accusation that “cherry-picking” of proxy sites is endemic in the paleo-climatological community that he disdainfully calls the “Hockey Team”. But this time, McIntyre has outdone himself, comparing the repeated use of the Yamal tree-ring chronology in paleoclimatology studies to a “crack cocaine” addiction.

Dropping the P-Bomb

Contraian Publication RecordThe blogosphere, or at least the climate contrarian part of it, has been up in arms over supposed misconduct and plagiarism on the part of climate scientists. First, there was a minor kerfuffle earlier this summer over NOAA’s citation of the surfacestation.org website instead of an online publication by Anthony Watts. That turned out to be just the latest in a series of accusations of misconduct from ClimateAudit.org.

But that was nothing compared to the furor over the Corrigendum to the Steig et al. paper, “Warming of the Antarctic ice-sheet surface since the 1957 International Geophysical Year” (just published in Nature). Steig et al. were accused of failing to acknowledge the role of Hu McCulloch in identifying an error in the calculation of trend significance. The corrigendum thus was held to constitute an act of plagiarism.

Meanwhile, some of the same bloggers who have risen up in righteous indignation and made groundless accusations against Steig et al, have been strangely silent regarding a real act of plagiarism, namely EPA economist Alan Carlin’s wholesale appropriation without attribution of large swathes of Patrick Michaels’ World Climate Report.

And, of course, an examination of the accusations against Steig et al shows them to be completely baseless. In fact, Hu McCulloch has apparently already withdrawn his accusations, although at present we have yet to see any apologies or retractions from Steig et al’s accusers.

Canadians front and centre at 2nd Heartland Conference

Heartland Conference Logo - March 8-10, 2009

The “climate change skeptic” right-wing think tank Heartland Institute has been quietly updating its list of almost 60 speakers for the second annual International Conference on Climate Change to be held in New York this March – and Canadian skeptics are front and centre. And in at least two cases, the official affiliations listed for speakers appear unlikely to be bona fide.

Last year’s inaugural event was derided by climate scientists as a PR sham masquerading as a scientific conference. Conference speakers, most of whom are not practicing climate scientists, are paid a generous honorarium and all travel expenses. Funding sources are not disclosed, but the Heartland Institute has received $676,000 from ExxonMobil since 1998.

This year’s meeting will feature first time invitee Stephen McIntyre, founder of the popular ClimateAudit blog, as one of six headliners. McIntyre is described by Heartland as a “devastating critic of the temperature record of the past 1,000 years”, but has published only one peer-reviewed article in a recognized science journal.

Interestingly, McIntyre’s listed affiliation is with the University of Toronto. McIntyre’s connection to the University is unclear, although he does apparently have a University email address.

Among the other five confirmed Canadian speakers, undoubtedly the most controversial is Lawrence Solomon, listed as affiliated with the National Post, a national Canadian daily newspaper. Solomon is the author of The Deniers, a book based on a long series of individual profiles written for the Post. He has recently launched attacks in the Post on Michael Mann, director of the Earth System Science Center at Penn State University, as seen  here and here. Solomon is executive director of Energy Probe, a non-profit group that “works for  environmental sustainability by promoting property rights.” (Closer scrutiny of this group  is clearly warranted, but will have to wait for a future post).
