Mann Misrepresents the EPA – Part 1

In today’s post, I will return to my series on false claims in Mann’s lawsuit about supposed “exonerations”. ( For previous articles, see here). One of the most important misconduct allegations against Mann – the “amputation” of the Briffa reconstruction in IPCC TAR – was discussed recently by Judy Curry, who, in turn, covered Congressional testimony […]

Hide the Decline II

On March 8, Michael Mann’s lawyers, Cozen O’Connor, sent a legal letter to Minnesotans for Global Warming (of the famous Hide the Decline video) threatening them, ironically, with misappropriating Mann’s likeness and, almost as an afterthought, defaming him “by leaving viewers with the incorrect impression that he falsified data to generate desired results in connection […]

IPCC and the “Trick”

Much recent attention has been paid to the email about the “trick” and the effort to “hide the decline”. Climate scientists have complained that this email has been taken “out of context”. In this case, I’m not sure that it’s in their interests that this email be placed in context because the context leads right […]

IPCC: “Inappropriate” to show the decline

One reviewer of the IPCC 2007 Assessment Report specifically asked IPCC not to hide the decline. The reviewer stated very clearly: Show the Briffa et al reconstruction through to its end; don’t stop in 1960. Then comment and deal with the “divergence problem” if you need to. Don’t cover up the divergence by truncating this […]

New!! Data from the Decline

For the very first time, the Climategate Letters “archived” the deleted portion of the Briffa MXD reconstruction of “Hide the Decline” fame – see here. Gavin Schmidt claimed that the decline had been “hidden in plain sight” (see here. ). This isn’t true. The post-1960 data was deleted from the archived version of this reconstruction […]

The Deleted Portion of the Briffa Reconstruction

“Hide the decline” refers to the decline in the Briffa MXD temperature reconstruction in the last half of the 20th century, a decline that called into question the validity of the tree ring reconstructions. (I’m going to analyze the letters on another occasion.) In the IPCC Third and Fourth Assessment Reports, IPCC “hid the decline” […]

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. […]

Prometheus on Climateaudit on Briffa MXD

Roger Pielke at Prometheus has some kind words for my comments on the IPCC "editing" of the Briffa MXD series in their spaghetti graph. Good for Chris Mooney and good for Climate Audit. Such close attention can help both the IPCC and NASA realize that people are paying attention to their use of information and […]
