Continued from previous post link. The data associated with the Climategate “dirty laundry” email had other interesting information on Mann’s calculation of confidence intervals and the related calculation of RE statistic. This post draws heavily on offline comments by Jean S and UC, both long before and after Climategate. The left panel below is Tim Osborn’s […]
As the date approached for the Mann-Steyn/Simberg libel trial, I’ve been reviewing my files on MBH98 and MBH99. It’s about 15 years since I last looked at these issues. While revisiting these issues, I re-examined some data associated with the notorious “dirty laundry” Climategate email (link) – excerpt shown at right – that turns out […]
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, […]
Two major new BBC programs, The Trick and the Hack That Changed The World, re-visit 2009 Climategate events on the eve of UK hosting the most recent international climate get-together. I was interviewed by The Hack and mentioned in The Trick as a villain. In today’s article, I’m going to propose a theory of the […]
On October 18, 2021, BBC (producer Owen Sheers) aired a “conspiracy thriller” entitled The Trick – though a more complete title would have been The Trick… to Hide the Trick to Hide the Decline. In a forthcoming post, I’ll do a longer analysis of the trick in which, to borrow a phrase from Climate Audit […]
Next, the PAGES2019 0-30N latband. Their CPS reconstruction (CPS) for the 0-30N latband (extracted from the global reconstruction) looks almost exactly the same as reconstructions for the 0-30S and 30-60S latbands. However, none of the actual proxies in this latband look remotely like the latband reconstruction, as I’ll show below. In the course of examining […]
In a Climategate email. Keith Briffa famously sneered at Michael Mann’s claim that a temperature reconstruction could represent a hemisphere, including the tropics, by regressing a “few poorly temperature respresentative tropical series” against “any other target series” – even the trend of Mann’s own “self-opinionated verbiage” as follows: I am sick to death of Mann […]
The 30-60N latitude band gets lots of attention in paleoclimate collections – probably more proxies than the rest of the world combined. The 30-60S latitude band is exactly the same size, but it is little studied. It is the world of the Roaring Forties and Furious Fifties, a world that is almost entirely ocean. The […]
About 20% of the PAGES 2019 proxies are 50 Asian tree ring chronologies, all of which were originally published as chronologies in PAGES (2013). At the time, none of these series (and certainly not in these digital versions, had ever been published in technical literature, peer reviewed or otherwise. Nothing in the Supplementary Information to […]
Although climate scientists keep telling that defects in their “hockey stick” proxy reconstructions don’t matter – that it doesn’t matter whether they use data upside down, that it doesn’t matter if they cherry pick individual series depending on whether they go up in the 20th century, that it doesn’t matter if they discard series that […]
