Barton "Op Ed"

US Congressman Joe Barton expressed some thoughts here (link courtesy of Jerry Brennan).

Bradley's Data Archiving

Here is a discussion of two of Bradley’s answers to questions from the House Committee letter pertaining to federal grants and archiving.

Is Hughes in compliance with data archiving requirements?

Hughes’ letter to Barton says that NSF issued him an opinion that he was in compliance with all NSF and US government obligations regarding access to data. Why would NSF go out of its way to issue such an opinion letter? I wonder what due diligence that NSF did before issuing the opinion letter. Here […]

The Hill News on Barton

The Hill News, described as the newspaper "for and about Congress", says the following: It is decidedly odd to suggest that Barton, who as Energy Committee chairman is tasked with helping shape the nation’s energy policy, should not have any oversight of the science increasingly used to justify “¢’‚¬? indeed demand “¢’‚¬? a radical change […]

Answers to the House Committee on Cross-Validation Statistics

In a recent post, I showed that MBH had calculated cross-validation R2 statistics, but this information had been excluded from their summary of cross-validation statistics in their Supplementary Information here. We had surmised this in our original article, but had previously been unable to absolutely prove it. The House Committee requested information from M,B and […]

Alan Leshner, the CEO of the American Association for the Advancement of Science and Executive Publisher of Science, has written Rep. Barton objecting to the letters to Mann, Bradley and Hughes. The press release is here and the letter is online here. now

Conflict of Interest #2

In a previous post, I discussed, in general terms, the issue of the conflict of interest between being an IPCC reviewer and being an active protagonist in the field. Here I illustrate the problems with specific reference to MBH98, arguing that the running text of IPCC TAR made misleading claims about the MBH98 hockey stick […]

Conflict of Interest #1

One of the important issues raised in the House Committee Letters was the potential conflict of iinterest between individuals in their capacity as IPCC authors reviewing (and even promoting) their own research. Kevin Vranes, Roger Pielke and Hans von Storch in different ways at Prometheus have all discussed the problem, with a surprising degree of […]
