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 […]

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