More Phil Jones Correspondence

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 […]

Swindle and the Stick

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 […]

GHCN Adjusted Data Isn't Good Enough for D'Arrigo et al

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 […]

RMS and Sulphate Emissions

I had nothing to do with the Swindle presentation, and by and large the issues presented in Swindle are ones that I have not discussed here. I’m discussing these issues merely because it’s in the news. A few days ago, I discussed the accusation by RMS and the 37 profs that Swindle had not used […]

More on Hegerl et al 2006 Non-Confidence Intervals

There are a few other blogs that from time to time do detailed analyses of what people are doing, not dissimilar in format to what I do. Last year, in Apr 2006 shortly after publication, I observed here that the upper and lower confidence intervals of Hegerl et al crossed over. In Feb 2007, Tapio […]

More on the Divergence Problem

Two new things on the Divergence Problem. The IPCC First and Second Drafts did not contain a whisper of a mention of the divergence between ring widths and density in the second half of the 20th century, although this is rather an important issue. It came up at the NAS Panel and was completely unresolved […]

Risk Management Solutions Ltd and the 37 Professors

In the complaint about Swindle by Risk Management Solutions Ltd., endorsed by a gaggle of 37 professors, they allege that the Swindle graphic of 20th century claims in connection with 20th century temperature change contains the following misrepresentations: Measurements from meteorological stations that have been published by NASA and other agencies show that the there […]

von Storch and Zorita blog on the Hockey Stick

At a Nature climate change blog, von Storch and Zorita write: In October 2004 we were lucky to publish in Science our critique of the hockey-stick’ reconstruction of the temperature of the last 1000 years. Now, two and half years later, it may be worth reviewing what has happened since then. The publication in 2004 […]

The Swindle Complaint and Myles Allen

Bob Ward, who you may remember as the author of various complaints from the U.K. Royal Society, is now employed at Risk Management Solutions Ltd. In his business capacity as Director, Global Science Networks, Risk Management Solutions Ltd., he has filed a complaint about Swindle under a section of the broadcasting code which states: “Views […]
