The latest climate contrarian meme appears to be (baseless) accusations of scientific “gatekeeping” and “censorship”. Ross McKitrick provides an example of this unmistakable trend, with a blow-by-blow account of difficulties encountered in publication of his upcoming paper on the supposed contamination of the surface temperature record. The new paper purports to debunk a single statement in the 2007 IPCC Fourth Assessment Report, one denigrating the conclusions of a previous paper by McKitrick and Patrick Michaels.
McKitrick criticizes the IPCC assertion that “locations of greatest socioeconomic development are also those that have been most warmed by atmospheric circulation“. He claims that other sections cited to support that statement do no such thing. But it turns out that McKitrick himself has it completely wrong, as he cites a passage concerning regional warming over the 21st century, instead of the actual relevant passage concerning the period 1975-2005.
Moreover a review of the relevant scientific literature reveals substantial flaws in the previous analyses of McKitrick and Michaels. That, rather than any close-mindedness or “censorship”, is the real reason why McKitrick’s analyses have become increasingly marginalized in the scientific literature, if not in the right-wing press.

Here is the first of an occasional series that will look back at the origins of various major players among Canada’s climate contrarians. And, quite appropriately, the honour of inauguration belongs to none other than our old, um, acquaintances, Friends of Science.
For the first time, we can confirm both financial and logistical support from an Albertan oil company, Talisman Energy, along with circumstantial evidence of the early involvement of a second, Imperial Oil (ExxonMobil’s Canadian subsidiary). We’ll also look at the key roles played by the de Freitas brothers, geologist Tim and climate skeptic Chris. And the story leads right to the heart of a key controversy reignited by the stolen CRU emails, namely the ongoing perversion of the scientific peer review system by “skeptic” scientists.
A raging controversy, one almost as hot as the record-breaking heat wave on the North American west coast, has broken out over a recent paper in the Journal of Geophysical Research (Atmospheres), a peer-reviewed periodical published by the American Geophysical Union (AGU).
Authors John McLean, Chris de Freitas and Bob Carter all have a long history of links to climate disinformation groups and associated PR campaigns (many of which lead back to Canadian spinmeister Tom Harris, director of the International Climate Science Coalition).
Now the trio have claimed that their analysis demonstrates that global warming is primarily a result of natural processes with little role for anthropogenic influences such as greenhouse gases.
A barrage of criticism has forced the authors and their champions to backpedal furiously. Along the way, a PDF of the paper has been removed from the New Zealand Climate Science Coalition (NZCSC) website, presumably to rectify an egregious copyright breach. Even worse, the NZCSC parent affiliate, the above-mentioned International Climate Science Coalition (ICSC), was caught substituting its preferred title for the actual one in its link to the paper.
And, of course, a look at the actual data clearly shows that the trio’s touted source of global warming, namely a 1976 “shift” in the El Nino Southern Oscillation (or ENSO), can not possibly account for the recent upward trend in temperatures. All this raises serious questions about JGR’s editorial processes, and leads to the inevitable conclusion that the paper should be withdrawn.
