Yesterday I mentioned that we had been invited to make a post at the Nature blog. The invitation was withdrawn today. On May 10, we received the following invitation: As you know, there was a recent post on our Climate Feedback blog by Hans Von Storch that discussed the hockey stick, without discussing your work […]
Paul H made the following statement in the context of the Swindle discussion: If a practising scientist selected a 1987 data set over more recent versions, failed to cite it correctly, altered the appearance of the data without a clear explanation and didn’t include the data from the last 20 years then I think we’d […]
I’ve found an unlikely ally in my questioning of the smoothing of MBH99 in the original publication and in IPCC TAR: Keith Briffa. Not that Briffa has posted a comment endorsing my observation. However, the smoothed version of MBH99 in Briffa et al 2001 (near contemporary with TAR) is virtually identical to what I got. […]
As I re-examined the IPCC TAR spaghetti , I noted that there was considerable evidence in Figure 2-21 that the Maestro himself is in the house and we should therefore be prepared for the unexpected. There is an interesting replication problem in the TAR spaghetti graph where I’d welcome ideas. Here’s the TAR spaghetti graph […]
I’ve been trying since 2003 to get detailed sample information from Lonnie Thompson on his tropical ice cores, some drilled 20 years ago. I reported on my most recent effort on Apr 19, 2007 under PNAS policies here. Thompson has once more obfuscated a journal by falsely telling them that everything already is archived (without […]
I was planning a new post on the truncation of the inconvenient 20th century downturn in the Briffa 2001 graphic in the IPCC graphic, that I observed some time ago here. Since data truncation is in the news, I was going to update the graphic in this post to better show just how cynical the […]
If you want one more inhomogeneity in station records, it seems that temperature measurements have been whitewashed – literally. The Stevenson screens used to be painted with whitewash which is a calcium carbonate with very specific infrared absorption properties. I gather that whitewash isn’t used much any more and so screens are routinely painted with […]
CA reader Geoff Sherrington, an Australian scientist, sends the following email exchange with Phil Jones in early 2006 (original post here). Geoff observes: there is a reluctance to answer direct questions with direct answers and a lot of red herrings thrown in. Readers can deduce what they like from the exchange, where Phil says he […]
The first complaint by RMS (and others) against Swindle seems to be about their handling of the Hockey Stick. A new complaint from someone at the University of Bristol includes a spaghetti graph, including MBH, saying that it shows that the newer reconstructions use “superior methods”, “supersede” the earlier results and that the old IPCC […]
D’Arrigo, Wilson et al 2007 is an interesting article on the Divergence Problem, about which I plan to post from time to time. Since we’ve been discussing temperature data recently – with special discussions of GHCN data problems in Russia, China and Australia, I thought that it would be interesting to draw attention to an […]
