In my previous post on Climategate I blithely said that nothing in the climate science email dump surprised me much. Having waded more deeply over the weekend I take that back.

The closed-mindedness of these supposed men of science, their willingness to go to any lengths to defend a preconceived message, is surprising even to me. The stink of intellectual corruption is overpowering. And, as Christopher Booker argues, this scandal is not at the margins of the politicised IPCC [Intergovernmental Panel on Climate Change] process. It is not tangential to the policy prescriptions emanating from what David Henderson called the environmental policy milieu [subscription required]. It goes to the core of that process.

One theme, in addition to those already mentioned about the suppression of dissent, the suppression of data and methods, and the suppression of the unvarnished truth, comes through especially strongly: plain statistical incompetence. This is something that Henderson's study raised, and it was also emphasised in the Wegman report on the Hockey Stick, and in other independent studies of the Hockey Stick controversy. Of course it is also an ongoing issue in Steve McIntyre's campaign to get hold of data and methods. Nonetheless I had given it insufficient weight. Climate scientists lean very heavily on statistical methods, but they are not necessarily statisticians. Some of the correspondents in these emails appear to be out of their depth. This would explain their anxiety about having statisticians, rather than their climate-science buddies, crawl over their work.

I'm also surprised by the IPCC's response. Amid the self-justification, I had hoped for a word of apology, or even of censure. (George Monbiot called for Phil Jones to resign, for crying out loud.) At any rate I had expected no more than ordinary evasion. The declaration from Rajendra Pachauri that the emails confirm all is as it should be is stunning. Science at its best. Science as it should be. Good lord. This is pure George Orwell. And these guys call the other side "deniers".

While I'm listing surprises, let me note how disappointed I was by The Economist's coverage of all this. "Leaked emails do not show climate scientists at their best," it observes. No indeed. I should say I worked at the magazine for years, admire it as much as ever, and rely on the science coverage especially. But I was baffled by its reaction to the scandal. "Little wonder that the scientists are looking tribal and jumpy, and that sceptics have leapt so eagerly on such tiny scraps as proof of a conspiracy," its report concludes. Tiny scraps? I detest anti-scientific thinking as much as The Economist does. I admire expertise, and scientific expertise especially; like any intelligent citizen I am willing to defer to it. But that puts a great obligation on science. The people whose instinct is to respect and admire science should be the ones most disturbed by these revelations. The scientists have let them down, and made the anti-science crowd look wise. That is outrageous.

Megan McArdle adopts a world-weary tone similar to The Economist's: this is how science is done in the real world. If I were a scientist, I would resent that. She has criticised the emails and the IPCC response to them, then says she still believes the consensus view on climate change. Well, that was my position at the end of last week, and I suppose it still is. But how do I defend it? There is far more of a problem here for the consensus view than Megan and ordinarily reliable commentators like The Economist acknowledge. I am not a climate scientist. In the end I have to trust the experts. That is what we are asked to do. "Trust us, we're scientists".

Remember that this is not an academic exercise. We contemplate outlays of trillions of dollars to fix this supposed problem. Can I read these emails and feel that the scientists involved deserve to be trusted? No, I cannot. These people are willing to subvert the very methods--notably, peer review--that underwrite the integrity of their discipline. Is this really business as usual in science these days? If it is, we should demand higher standards--at least whenever "the science" calls for a wholesale transformation of the world economy. And maybe some independent oversight to go along with the higher standards.

The IPCC process needs to be fixed, as a matter of the greatest urgency. Read David Henderson or the Wegman report to see how. And in the meantime, let's have some independent inquiries into what has been going on.

you righties have really latched on the climategate, as if disproves all the decades non-climategate global-warming science, even after climategate has been totally debuned.

Just another false drum to beat, like all the other rabble rousing bullshit that the righties are left with since they are bereft of real issues as they are of honesty and good faith.

Your arguments are so compelling. :rolleyes

From the Wegman report (investigation into "hockey stick" graph)


Ouch!




Findings

In general, we found MBH98 and MBH99 to be somewhat obscure and incomplete and the criticisms of MM03/05a/05b to be valid and compelling. We also comment that they were attemptingto draw attention to the discrepancies in MBH98 and MBH99, and not to do paleoclimatic temperature reconstruction. Normally, one would try to select a calibration dataset that is representative of the entire dataset. The 1902-1995 data is not fully appropriate for calibration and leads to a misuse in principal component analysis.

However, the reasons for setting 1902-1995 as the calibration point presented in the narrative of MBH98 sounds reasonable, and the error may be easily overlooked by someone not trained in statistical methodology. We note that there is no evidence that Dr. Mann or any of the other authors in paleoclimatology studies have had significant interactions with mainstream statisticians.

In our further exploration of the social network of authorships in temperature reconstruction, we found that at least 43 authors have direct ties to Dr. Mann by virtue of coauthored papers with him. Our findings from this analysis suggest that authors in the area of paleoclimate studies are closely connected and thus ‘independent studies’ may not be as independent as they might appear on the surface. This committee does not believe that web logs are an appropriate forum for the scientific debate on this issue.

It is important to note the isolation of the paleoclimate community; even though they rely heavily on statistical methods they do not seem to be interacting with the statistical community. Additionally, we judge that the sharing of research materials, data and results was haphazardly and grudgingly done. In this case we judge that there was too much reliance on peer review, which was not necessarily independent. Moreover, the work has been sufficiently politicized that this community can hardly reassess their public positions without losing credibility. Overall, our committee believes that Mann’s assessments that the decade of the 1990s was the hottest decade of the millennium and that 1998 was the hottest year of the millennium cannot be supported by his analysis.

Just goes to show....he who agrees with Darrin is a fool who just doesn't know it yet

The so-called climategate doesn't debunk anything. It does however, poison the well of conclusions. Anybody who works in analysis knows that garbage in/garbage out.
