The Wegman and North Reports for Newbies

In recent discussion of the Weblog 2007 Awards, several commenters at other blogs have argued that our criticisms of the Mannian parlor tricks have been “thoroughly refuted and discarded by climatologists, published in a credible journal”; that “other professionals in the field who also have “looked in great detail at the problem at hand” and […]

Wegman's replies to Stupak

I know this is well after the event, but Dr Wegman’s extensive and detailed responses to Rep Stupak‘s written questions are interesting reading. I’m not aware that Steve linked to this document before. Beware though: the file is 10MB in size, so I’d recommend a right click followed by “Save Target as” – otherwise your […]

More Tangled Webs

Here’s something amusing. Mann has written to the House Energy and Commerce Committee, arguing that we made a fundamental and obvious mistake in how we calculated AR1 coefficients for the North American tree ring network, which exaggerated the HS-ness of the simulated hockey sticks – a mistake that Ritson has now supposedly picked up and […]

Take a Ritalin, Dave

The Team have snarled back at Wegman here . They’ve posted up an August 16, 2006 letter from David Ritson to Waxman, accusing Wegman of not responding with a request for information that had been outstanding for almost 3 weeks (?!?) . Yes, you read it right. Jeez, I’ve been waiting almost three years for […]

Sciencemag on House E&C Hearing

Richard Kerr of Science has reported on the House Energy and Commerce Committee hearings. Having lived through the hearings, it’s interesting to see how they get characterized. For example, Kerr says: He [North] said he doesn’t disagree with Wegman’s main finding that a single year or a single decade cannot be shown to be the […]

Data Request to NAS

I’ve set up a new category at right entitled "Archiving" which cross-classifies many of the posts on data archiving and requests. A review from this time last year is here . Since then, I’ve had correspondence with Moberg and Nature, which has resulted in winkling out the other Moberg series (which I’ve yet to process); […]

Whitfield subCommittee II: Mann under fire

Today’s hearing in Congress will be sound-only (for some reason), although it might be visually on CSPAN3 (check your listings) The speakers will be: Michael Mann Edward Wegman John Christy Ralph Cicerone Stephen McIntyre Jay Gulledge As soon as the link is available, I’ll post it up. Update: Link is here and video feed from […]

Survivor Season 8: the Hockey Team – the Mann Overboard Episode

Well, back from Washington. I’m not very good at describing reactions and impressions and touchy-feely stuff like that; I’m more comfortable describing what’s different with the 53rd and 84th series out of 112, but I’ll try.

Grapevine: Mann to testify on 27th July

This just in: Apparently Dr Michael Mann is to testify in front of the Whitfield Subcommittee (I think) on July 27th at 2pm EDT. I assume that our readers want to tune in to see what happens.

Whitfield SubCommittee: Edward Wegman Testimony

Wegman goes through his conclusions in the report. Highlights: “The decentering error preferentially produces Hockey Sticks” ” Decentering has a big effect on reconstruction” ” With proper centering, the Hockey Stick shape disappears” “Dr Mann has unusually large reach with the other 43 authors” “Peer review is not as independent as would normally be the […]
