Tim Lambert was quick to pounce on Ross McKitrick’s programming error in calculating cosine(latitude) in a paper not involving me, so it’s ironic to see Lambert’s apparent failure to understand Mann’s erroneous use of cosine(latitude) in his temperature PC calculations, even when brought to his attention. Ed Snack has had an interesting exchange with Tim […]
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 […]
Just for reference: here’s the code excerpt where Mann calculates the cross-validation R2 statistics and then writes it to file. You can see the original code at ftp://holocene.evsc.virginia.edu/pub/MANNETAL98/METHODS/multiproxy.f.{Update – http://www.meteo.psu.edu/holocene/public_html/shared/research/MANNETAL98/METHODS/multiproxy.f ] Search down using corrnhem or verif1,out. There is no "if" as to whether he calculated the cross-validation R2 statistic.
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 […]
Mann has just(July 2005) archived a fortran program at ftp://holocene.evsc.virginia.edu/pub/MANNETAL98/METHODS/multiproxy.f. {Update: see here] Here are my first thoughts on this.
At Steve’s request, I’ve turned off the threaded comments and reinstated the “numbered comments”. This means that if comments are held up for moderation or deleted, references to comment numbers will go astray. I’m also experimenting with a new plug-in to enable commenters to preview their comments prior to submission. This should help all of […]
It will take a while to go through the responses of Mann, Bradley and Hughes. I’ve taken a first look at the new source code and will commenting on it in due course. I have no information on responses from NSF and IPCC, other than what I read in the Nature interview with the Chairman […]
4 Comments have been submitted to GRL to date on McIntyre and McKitrick [2005]. We reported previously that the Wahl and Ammann comment was rejected (although this has not been acknowledged at the UCAR website.) A second comment has now been rejected. I think that there is a good chance that the other two Comments […]
There have been posted up at realclimate here. I’ll look at them today. “Public access” to Mann’s FTP site includes blocking: I (and my neighbors on my street who use the same internet server) continue to be blocked from access to Mann’s FTP site and I’ll have to go to another IP address to look […]
