Daily Mail: Special Investigation

Daily Mail has detailed coverage on “hide the decline”.

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 […]

Gerry North Doesn’t Understand the “Trick”

Gerry North told the Washington post that the NAS panel did exactly the same thing as Phil Jones’ trick. (Dec. 1, 2009) North is talking through his hat. North: We put the tree ring record on the graph and stuck the instrument record on for the last 50 years in exactly the way [Phil] Jones […]

Still Hiding the Decline

Even in their Nov 24, 2009 statement, the University of East Anglia failed to come clean about the amount of decline that was hidden. The graphic in their statement continued to “hide the decline” in the Briffa reconstruction by deleting adverse results in the last part of the 20th century. This is what Gavin Schmidt […]

Replicating the “Trick” Diagram

Michael Mann, Dec 2004 No researchers in this field have ever, to our knowledge, “grafted the thermometer record onto” any reconstruction. It is somewhat disappointing to find this specious claim (which we usually find originating from industry-funded climate disinformation websites) appearing in this forum [realclimate]. Phil Jones, Nov 1999 I’ve just completed Mike’s Nature trick […]

“A good way to deal with a problem”

In the UEA statement of Nov 24, 2009, Phil Jones said: CRU has not sought to hide the decline. Indeed, CRU has published a number of articles that both illustrate, and discuss the implications of, this recent tree-ring decline, including the article that is listed in the legend of the WMO Statement figure. It is […]

The Trick

For the benefit of new readers, we discussed some aspects of the “trick” at Climate Audit in the past. Obviously, the Climategate Letters clarify many things that were murky in the past. On the left is a blowup of IPCC 2001 Fig 2.21 showing where the Briffa reconstruction (green) ends. More on this below.

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 […]

Mike’s Nature trick

So far one of the most circulated e-mails from the CRU hack is the following from Phil Jones to the original hockey stick authors – Michael Mann, Raymond Bradley, and Malcolm Hughes.
