Wegman Scandal: Attack on climate scientists based on shoddy scholarship

October 4, 2010

John Mashey assembled a massive document that nails down the case that bad science and politics make the complaints against scientists and the science that indicates global warming occurs, and can be attributed to greenhouse gases.  It is a scandal, though it’s unlikely to be reported that way.

Mashey’s entire paper — and it’s very, very large — is published at Deep Climate.

Mashey’s paper indicts staff work done for Rep. Joe Barton, R-Texas — not that any of the voters in Barton’s district will let this major breach of ethics sway their votes, but those who want to vote against him can be gratified that they are on the moral side of the ballot.

Mashey wrote:

This report offers a detailed study of the “Wegman Report”: Edward J. Wegman, David W. Scott, Yasmin H. Said, “AD HOC COMMITTEE REPORT ON THE ‘HOCKEY STICK’ GLOBAL CLIMATE RECONSTRUCTION”(2006).

It has been key prop of climate anti-science ever since. It was promoted to Congress by Representatives Joe Barton and Ed Whitfield as “independent, impartial, expert” work by a team of “eminent statisticians.” It was none of those.

A Barton staffer provided much of the source material to the Wegman team. The report itself contains numerous cases of obvious bias, as do process, testimony and follow-on actions. Of 91 pages, 35 are mostly plagiarized text, but often injected with errors, bias and changes of meaning. Its Bibliography is mostly padding, 50% of the references uncited in the text.  Many references are irrelevant or dubious.  The team relied heavily on a long-obsolete sketch and very likely on various uncredited sources. Much of the work was done by Said (then less than 1 year post-PhD) and by students several years pre-PhD. The (distinguished) 2nd author Scott wrote only a 3-page standard mathematical Appendix.  Some commenters were surprised to be later named as serious “reviewers.”  Comments were often ignored anyway.  People were misused.

The Wegman Report claimed two missions: #1 evaluate statistical issues of the “hockey stick” temperature graph,  and #2 assess potential peer review issues in climate science.  For #1, the team might have been able to do a peer-review-grade statistical analysis, but in 91 pages managed not to do so.  For  #2, a credible assessment needed a senior, multidisciplinary panel, not a statistics professor and his students, demonstrably unfamiliar with the science and as a team, unqualified for that task.   Instead, they made an odd excursion into “social network analysis,” a discipline  in which they lacked experience, but used poorly to make baseless claims of potential wrongdoing.

In retrospect, the real missions were: #1 claim the “hockey stick” broken and #2 discredit climate science as a whole. All this was a facade for a PR campaign well-honed by Washington, DC “think tanks” and allies, underway for years.

Now, if only Mashey had some e-mails stolen from Joe Barton, we could get some traction on the issue, eh?  ::wink-wink, nudge-nudge::

One may wonder what it will take to rehabilitate the skeptical side of the debate, to the point that they contribute more than mau-mauing.

Mashey’s paper makes that case that Joe Barton worked hard to pull off a great, hoaxed political smear, with a high degree of success.  Who will have the backbone to do anything about it?  Global cooling will proceed to the next ice age before any Republican shows backbone, I predict.

But, how long before the Fort Worth Star-Telegram or the Dallas Morning News picks up the story?

Other Texas bloggers?  Anyone?

It’s not an air-tight legal brief (I could quibble with some of the legal material), but in a better world, a world where politicians actually do good politics and public servants do public service, the House Rules Committee and Ethics Committee would be reading Mashey’s piece, and asking pointed questions.  U.S. attorneys in Washington, D.C., and the Northern District of Texas, would also be downloading Mashey’s piece, and puzzling it out.  Journalists in Dallas, Fort Worth, Austin, Galveston and Houston in Texas, and Washington, D.C., and New York, would also be poring over the piece.  Ken Cuccinelli in Virginia would also be paying attention to it, if he were concerned about justice.
