Inventory of Hide-the-Decline

In a recent post, I reported on the diagram in Jones 1998 (Science), which pushed hide-the-decline a year earlier than my previous inventory. (The Briffa bodge, an earlier technique, dates back to 1992 and Jones 1998 is a sort-of transition from the Briffa bodge to truncation as hide-the-decline technology.) I’ve had a few requests for […]

Another Porky from Mann, Williams and Fontaine

Jean S has spotted a highly amusing entry in Mann’s CV. The entry yields yet another porky in Mann’s pleadings. The Muir Russell panel had conceded that the WMO 1999 diagram and related IPCC 2001 diagrams (the two most discussed hide-the-decline diagrams) were “misleading”. CEI reported this in their original Memorandum in December 2012 For […]

The Original Hide-the-Decline

In a twitter exchange among Jean S, Ronan Connolley and Tim Osborn, Ronan drew attention to an early spaghetti graph in a comment on MBH98 published by Phil Jones in Science on the day after (Apr 24, 1998) publication of Mann et al 1998. The Briffa reconstruction is in purple below. Like IPCC 2001, it […]

Mann’s New Memorandum

Michael Mann’s reply brief in the Court of Appeals has been posted here. Its main points are very similar to their reply memoranda of January 2013 (to CEI; near identical to NR) Some comments have been accumulating on an unrelated topic. Please comment on this thread. I’ll try to write something over the next couple […]

Rule N revisited

PCA was also performed on certain proxy sub-networks (spatially dense regional networks of tree-ring data available separately in different continents) as means of dimensional reduction of the predictor network. In this case, the procedure...Show More Summary

Who Wrote EPA’s “Myths vs Facts”?

The Mann Statement of Claim prominently displayed, as one of only two quotations from the “inquiries”, an extended quotation from the Myths vs Facts webpage, included as one of three Resources accompanying the EPA decision denying reconsideration...Show More Summary

Mannomatic smoothing: technical details

This post is rather technical, and it is intended mainly for the historical completeness. So unless you are very, very interested in the tiny technical details of the HS saga, you can safely skip this. As most readers are aware, and stated in my post few hours after CG broke out, Mike’s Nature trick was […]

Who wrote the EPA documents?

Jean S writes (transferred from a comment with the addition of a few headings): A question for the experts: is it known who wrote and who were used as experts in the EPA documents? If not, is that information considered public (i.e., obtainable under FOIA or similar)? The reason I ask is that I get […]

Misrepresentations and the Tainted Narrative of Mann’s Complaint

In a recent post, I observed that Mann’s Statement of Claim contained a bizarre misrepresentation about the nature of Mann’s research, as it falsely credited Mann with being “one of the first” to document the increase in 20th century temperatures. Reader PhilH, a retired judge, observed that, on its own, the misrepresentation was merely odd and that […]

The “Discovery” of the EPA Inquiry

One of the essential elements in Mann’s reliance on EPA findings is his assertion that his supposed exoneration by EPA had been “widely available and commented” on in the media and had been “read by the Defendants”: All of the above reports and publications were widely available and commented upon in the national and international […]

EPA on Mann’s “Fraud” Invective

Michael Mann, now feigning sensitivity towards Mark Steyn’s use of the word “fraudulent”, used identical language in the Climategate emails against critics without the slightest compunction. Mann’s hypocrisy has been widely noted. Unpublicized...Show More Summary

Spam

During the past few months, the volume of comment spam from spambots has increased by an order of magnitude. Right now, this blog receives about 1 spambot comment per minute. Akismet and other spambot blocking services do an excellent job and without such software, it would be impossible for blogs to function. Nonethelss, I’ve noticed […]

Yet Another Misrepresentation in the Mann Pleadings

In today’s post, I’ll discuss another misrepresentation in Mann’s Statement of Claim, one in which Mann bizarrely misrepresented the nature of his own research, falsely claiming credit for being “one of the first” to “document” the increase in 20th century temperatures. This particular false claim was in the same paragraph as Mann’s false claim to […]

ACLU and National Media Intervene in Mann v Steyn et al

I get the sense that the Washington libel community and U.S. national media have belatedly woken up to the potential threat of Mann v Steyn and that the tide is now starting to run strongly against Mann in the anti-SLAPP proceedings. The most visible evidence of this is an impressive Amici brief from the ACLU […]

WG2 Misleads on Undernourishment Trend

Food security was one of the touchstone issues of the IPCC WG2 Summary for Policy Makers. In its chapter on food security (Chapter 7), IPCC’s single statement on changes on undernourishment was that 75 million were added to the undernourishment rolls between 2003-5 and 2007: FAO’s provisional estimates show that, in 2007, 75 million more […]

Paper justifying AR4’s use of a uniform prior for estimating climate sensitivity shown to be faulty

This is a guest post by Nic Lewis.   In July 2004 the IPCC held a Working Group 1 (WG1) Workshop on climate sensitivity, as part of the work plan leading up to AR4. In one session, Myles Allen of Oxford university and a researcher in his group, David Frame, jointly gave a presentation entitled […]

Cook’s Trick

In today’s post, I’m going to present a narrative of Richard Tol’s efforts to obtain rater ID and timestamps from the University of Queensland. See pdf here. While there have been a number of references to these efforts, few readers and commenters will (or can reasonably) spend the time to pull the threads together. Tol […]

Cook’s Fake Ethics Approval

For over a year, John Cook and the University of Queensland have repeatedly refused Richard Tol’s requests for information on rater ID and timestamps for the SKS ratings for Cook et al 2013. Recently there have been two events that shed new light on the dispute. First, in mid-May Brandon Shollenberger located the requested information […]

New Paper by McKitrick and Vogelsang comparing models and observations in the tropical troposphere

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 […]

Was Lawson Right about the UK Floods?

In February 2014, Nigel Lawson and Brian Hoskins (Chair of the Grantham Institute for Climate Change) appeared on the BBC’s Today show to answer whether there was “a link between the rain in recent days and global warming”. Lawson, an experienced man of affairs though not a “climate scientist”, briefed himself on the matter and […]
