In an online trailer for a new climate documentary, James Hansen, presumably exhausted from answering “niggling questions” at a gala Lehman Bros dinner tells the film-maker: I’m not going to use McIntyre’s name. The problem of name usage has been recently considered in several important philosophy workshops and conferences. On the top right, I linked […]
A data set that was almost as controversial in MBH98 as the Graybill bristlecones was the Gaspé cedar chronology used by Jacoby and d’Arrigo. An interesting new cedar chronology from Quebec has just appeared at NCDC, shown below. The third chronology shown below is an unreported update to the Gaspé series. I reported the unreported […]
Here’s another interesting mystery in Mann et al 2008. Their SI table rtable1209 reports correlations to 1850-1995 instrumental temperature. The correlations reported in their PNAS SI Table SD1 sets all but 484 “significant” values to NA, so the r1209 table is more comprehensive. The instrumental version supposedly used in their calculations is now archived at […]
Jeff Id has identified another intriguing mystery in the arduous problem of determining what Mann’s realdata was. Jeff observed that the version of the Luterbacher lutannt10 series in Mann’s infilled data version allproxy1209 was different than the version of lutannt10 in allproxyoriginal (Sep 5 version), illustrating this as below: I’ve verified this information; below is […]
Discussed here with embedded youtube clips. Here is a clip on the Stick. Try not to puke.
My interest in climate change derived in part from experience in the stock market where “consensus” is not infrequently established in favor of opinions that are completely incorrect. And, in many cases, the people promoting the views are competent and serious people. How are such things possible? I read about the Bre-X and Enron failures, […]
A reader writes in about Hansen’s submission at the Kingsnorth trial. I’m posting up a thread under a couple of conditions. Hansen’s take on scientific matters is influential and important and discussion of scientific topics will be permitted. Please do not post on anything that remotely touches on policy. Please do not make posts complaining […]
On Sep 2, I was getting ready to report on my trip to Italy and my presentation to the World Federation of Scientists seminar in Erice, Sicily, when I was rudely interrupted by the publication of Mann et al 2008. It will take time to fully parse the situation, but the main framework is pretty […]
