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 […]

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 […]

George Zimmerman’s Libel Lawsuit

Last week, a Florida court dismissed the libel suit of George Zimmerman e.g. here. In today’s post, I’ll discuss aspects of this decision, which are relevant to Mann’s libel suit against Steyn and others. Figure 1. Two libel plaintiffs: left – George Zimmerman; right – Michael Mann.

Abram et al 2014 and the Southern Annular Mode

In today’s post, I will look at a new Naturemag climate reconstruction claiming unprecedentedness (h/t Bishop Hill): “Evolution of the Southern Annular Mode during the past millennium” (Abram et al Nature 2014, pdf). Unfortunately, it is marred by precisely the same sort of data mining and spurious multivariate methodology that has been repeatedly identified in […]

Mann’s new paper recharacterizing the Atlantic Multidecadal Oscillation

A guest post by Nic Lewis   Michael Mann has had a paper on the Atlantic Multidecadal Oscillation (AMO) accepted by Geophysical Research Letters: “On forced temperature changes, internal variability, and the AMO”. The abstract and access to Supplementary Information is here . Mann has made a preprint of the paper available, here . More […]

Threats from the University of Queensland

As many readers are aware, John Cook of SKS refused to provide complete data on his 97% Consensus Project (flatly refusing date-stamp and anonymized rater identification.) Ironically, Cook left the data lying around the internet (to borrow a phrase from Phil Jones). In an incident remarkably similar to the Mole Incident, Brandon Shollenberger alertly located […]

IOP: expecting consistency between models and observations is an “error”

The publisher of Environmental Research Letters today took the bizarre position that expecting consistency between models and observations is an “error”.

The Cleansing of Lennart Bengtsson

Recently, Lennart Bengtsson undertook a positive dialogue with climate skeptics by joining the advisory board of the Global Warming Policy Foundation, an organization that attempts to represent rational skepticism. Instead of welcoming this initiative, the climate “community” has now cleansed Lennart Bengtsson by pressuring him to resign from the GWPF advisory board. Bengtsson’s discouraging resignation […]
