In today’s post, I will report on some excellent work on MBH98 by Hampus Soderqvist, who discovered an important but previously unknown Mike’s Nature Trick: Mann’s list of proxies for AD1400 and other early steps was partly incorrect (Nature link now dead – but see NOAA or here). Mann’s AD1400 list included four series that […]
In a recent post commenting on Rich Muller’s lecture of March 19, 2011 (here) – of which the Climategate portion is more or less the same as his Oct 14, 2010 lecture (online here), John Cook observes: It’s clear that “Mike’s Nature trick” is quite separate to Keith Briffa’s “hide the decline”. Muller has taken […]
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.
Introduction I thank Patrick Brown for his detailed response (also here) to statistical issues that I raised in my critique “Brown and Caldeira: A closer look shows global warming will not be greater than we thought” of his and Ken Caldeira’s recent paper (BC17).[1] The provision of more detailed information than was given in BC17, and […]
One of the central claims of The Trick, if not the most central claim, was that “hiding the decline” was nothing more than an inopportune phrase about a single diagram. It wasn’t. The “trick to hide the decline” was an inopportune, if revealing, phrase, but rather than the issue being limited to a single diagram, […]
Rahmstorf et al 2015 Figure 5 shows a coral d15N series from offshore Nova Scotia (see left panel below). The corresponding plot from the source is shown on the right. Original captions for both follow. There’s enough information in the figures and captions to figure out Rahmstorf’s next trick. See if you can figure it out […]
In today’s post, I’ll show that even Andrew Weaver was tricked by Mann’s IPCC 2001 hide-the-decline. Weaver’s incorrect belief that the IPCC diagram showed “four” “independent” “hockey sticks” constructed using “different techniques” led him to believe that the research was much solider than it really was (or is), to say that our focus on the Mann […]
I’m not sure McIntyre knows what ‘splicing’ is. To me it means cutting and joining two ends together. All Mann did was plot instrumental temperatures on the same axes, but he showed the whole record. Dana Nuccitelli There still seems to be a lot of confusion among Mann’s few remaining supporters as to why Phil […]
This is a guest post by Ross McKitrick. Tim Vogelsang and I have a new paper comparing climate models and observations over a 55-year span (1958-2012) in the tropical troposphere. Among other things we show that climate models are inconsistent with the HadAT, RICH and RAOBCORE weather balloon series. In a nutshell, the models not only […]
On Friday, the UK Information Commissioner ruled against my request for (1) the attachments to the Wahl-Briffa email that contained Wahl’s surreptitious changes to the AR4 Report from the language sent to reviewers to language much more favorable to Mann and Wahl; (2) Wahl and Ammann (2004, submitted), cited in the AR4 First Draft, the […]
