New Scientist, Juckes and Rob Wilson

Here’s something amusing in the New Scientist article, which includes a defence of the Stick. Their jpg is compiled by one Robert Wilson of the University of Edinburgh, who includes the reconstruction from Juckes 2006. Has Juckes been accepted or doesn’t this matter any more? Like IPCC, Rob has failed to show 1960-1994 values of […]

GISS Interruptus

GISS does not provide a coherent archive of station data (such as is available at GHCN.) As reported before, Nicholas developed a technique for downloading station data within R. Downloading the entire data set (which takes a minute or so from GHCN on a highspeed network) is laborious but automatic. I did this in the […]

Swindle and the IPCC TAR Spaghetti Graph

Our text for today remains: 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 all be asking serious questions about their professionalism. […]

Nature Blog Withdraws Invitation

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 The invitation was withdrawn today.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 […]

Replicating the Briffa et al 2001 MXD Reconstruction

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 […]

Briffa and MBH99 Smoothing

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. […]

The Maestro is in da house

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 […]

More Evasion by Thompson

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 […]

More Unreplicable Claims by the Team

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 […]

Whitewashing the Temperature Record

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 […]
