Mann and his bristlecones

Gavin Schmidt and others have claimed that the M08 usage of the Tiljander sediments didn’t ‘matter’, because they could “get’ a series that looked somewhat similar without the sediments. They’ve usually talked around the impact of the Tiljander series on the no-dendro reconstruction. But there are two pieces of information on this. A figure added […]

Make a stick, make a stick

NASA blogger Gavin Schmidt as part of his ongoing attempt to rehabilitate Mannian paleoclimate reconstructions, characterized here as dendro-phrenology, has drawn attention to a graphic posted up at Mann’s website in November 2009. In this graphic, Mann responded to criticisms that his “no-dendro” stick had been contaminated by bridge-building sediments despite warnings from the author […]

Climategatekeeping: Schmidt 2009

We’ve seen that Climategate emails provide evidence that Jones, Briffa and Cook took steps to block publication of articles that were perceived as potentially damaging. The Climategate documents also provide a glimpse of another aspect of Team gatekeeping – acting as peer reviewers of submissions by associates and friends. Phil Jones was a peer reviewer […]

Gavin's Guru and RCS Standardization

Obviously, there has been considerable controversy over the past few days over the Yamal data. First, let’s observe the continued silence of field dendros on the dispute. None have stepped forward so far to support Briffa’s use of 10 cores in 1990 (and 5 in 1995). As others have observed, their silence is rapidly becoming […]

BS09 and Mannian Smoothing

Many CA readers have probably noticed Lucia’s recent coverage of Benestad Schmidt (JGR 2009) (with the inevitable acronym BS09). BS09 was an effort by B&S to verify Scafetta and West. realclimatescientists can also be climateauditors, I guess. It’s too bad that they don’t spend the same amount of energy examining Mann et al 2008 or […]

Gavin and the PC Stories

How many principal components to retain? Recent readers of Climate Audit may not realize that this was an absolute battleground issue of MBH and Wahl and Ammann. In one sense, it was never resolved with MBH back in 2003-2005, but that was before the existence of blogs made it possible to focus attention on problems. […]

Nierenberg re Schmidt re McKitrick and Michaels

Nicolas Nierenberg has taken a look here at Gavin Schmidt auditing of McKitrick and Michaels. He previously reported here on the analysis: Anyway I have written an analysis of spatial autocorrelation as it relates to S09 and MM07. My conclusion is that the primary result in MM07 was not affected by spatial autocorrelation, which is […]

Gavin on McKitrick and Michaels

Ross writes: Has Gavin posted on his IJOC paper? [SM - yes. At RC today.] I will head over tomorrow to have a look. Not today–it’s very sunny here and the ice rink beckons. I am not sure how replication plays into the issue, since I posted my data and code from the get-go. I […]

Gavin’s Complaint

Many bemused blog readers know by now that Gavin Schmidt aka Mystery Man has taken a few hours off from his dedicated and long-standing interest in station data integrity to file a complaint to the University of Colorado about a post that Roger Jr wrote about the Gavin Affair. Gavin has refused Pielke permission to […]

Gavin’s “Mystery Man” Revealed

On Monday, Feb 2, Gavin Schmidt explained some “ethics” to realclimate readers as follows: [Response: People will generally credit the person who tells them something. BAS were notified by people Sunday night who independently found the Gill/Harry mismatch. SM could have notified them but he didn't. My ethical position is that it is far better […]
