Tim Osborn ([1]t.osborn@uea.ac.uk) is probably the best person to contact for further details, in Keith's absence, mike On Sep 29, 2009, at 5:08 PM, Michael Mann wrote: Hi Andy, I'm fairly certain Keith is out of contact right now recovering from an operation, and is not in a position to respond to these attacks. However, the preliminary information I have from others familiar with these data is that the attacks are bogus. It is unclear that this particular series was used in any of our reconstructions (some of the underlying chronologies may be the same, but I'm fairly certain the versions of these data we have used are based on a different composite and standardization method), let alone any of the dozen other reconstructions of Northern Hemisphere mean temperature shown in the most recent IPCC report, which come to the conclusion that recent warming is anomalous in a long-term context. So, even if there were a problem w/ these data, it wouldn't matter as far as the key conclusions regarding past warmth are concerned. But I don't think there is any problem with these data, rather it appears that McIntyre has greatly distorted the actual information content of these data. It will take folks a few days to get to the bottom of this, in Keith's absence. if McIntyre had a legitimate point, he would submit a comment to the journal in question. of course, the last time he tried that (w/ our '98 article in Nature), his comment was rejected. For all of the noise and bluster about the Steig et al Antarctic warming, its now nearing a year and nothing has been submitted. So more likely he won't submit for peer-reviewed scrutiny, or if it does get his criticism "published" it will be in the discredited contrarian home journal "Energy and Environment". I'm sure you are aware that McIntyre and his ilk realize they no longer need to get their crap published in legitimate journals. All they have to do is put it up on their blog, and the contrarian noise machine kicks into gear, pretty soon Druge, Rush Limbaugh, Glenn Beck and their ilk (in this case, The Telegraph were already on it this morning) are parroting the claims. And based on what? some guy w/ no credentials, dubious connections with the energy industry, and who hasn't submitted his claims to the scrutiny of peer review. Fortunately, the prestige press doesn't fall for this sort of stuff, right? mike I'm sure you're aware that you will dozens of bogus, manufactured distortions of the science in the weeks leading up to the vote on cap & trade in the U.S. senate.
