Anyone who has blogged, or even just hangs around blogs more than they should, is familiar with the “pingback”. You know, it’s that automatically generated comment that signals that another blog has referred to a particular post. Yesterday, I got this “pingback” from a blogger called Delayed Oscillator (or “delayed.oscillator” as it is formatted there) and decided to follow it up.
And am I ever glad I did. DO (pronounced Dee-Oh), as I will call this blogger (I hope that’s OK!) has brought a welcome expert perspective to the discussion of the Steve McIntyre-Keith Briffa controversy, said by certain economists and business section editors to expose the global warming sham once and for all. In a two-part series of posts, DO shows why it “ain’t necessarily so” (to say the least).
By now, anyone who follows the climate blog wars knows that a new battle is underway over the standard temperature reconstruction popularly known as the “hockey stick”. Although it has been declared thoroughly shattered many times, apparently it must be attacked again and again.
Over the last few days, self-appointed climate “auditor” Steve McIntyre has made several insinuations concerning the work of UK dendro-climatologist Keith Briffa, focusing on the recently released Yamal series of tree-ring measurements. Along the way, he has once again rehashed an oft-repeated accusation that “cherry-picking” of proxy sites is endemic in the paleo-climatological community that he disdainfully calls the “Hockey Team”. But this time, McIntyre has outdone himself, comparing the repeated use of the Yamal tree-ring chronology in paleoclimatology studies to a “crack cocaine” addiction.
The following is an email exchange with Dr. Mojib Latif, Professor for Climate Physics at the Leibniz Institute of Marine Sciences at Kiel University, concerning his recent work in decadal prediction. My original email was written to draw attention to misrepresentations of Latif’s work and recent comments, as discussed in the immediately following post.
The following is an edited transcript of key excerpts from Dr. Mojib Latif’s presentation at the World Climate Conference 3, held in Geneva in September 2009. Also see my subsequent post on misinterpretations and distortions of these remarks.
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.
The kerfuffle over the EPA’s so-called “suppression” of Alan Carlin continues apace, with two new commentaries from right-wing columnists. Both syndicated columnist Mark Steyn and the Wall Street Journal’s Kim Strassel cite Carlin in support of the tired contrarian assertion that “global temperatures are on a downward trend”. (Of course, at the risk of repeating myself, this has been debunked thoroughly here, there and everywhere, as John Lennon might have put it)
But, once again, it turns out that Carlin did not write certain relevant key passages himself, and also failed to attribute them to the original author.
[Update, July 8: In another astonishing twist, I have just discovered that Marlo Lewis, the National Review columnist whose piece Carlin lifted as discussed below, is – wait for it – a Senior Fellow at the Competitive Enterprise Institute, which just happens to be the right-wing think tank that has been touting the so-called “suppression” of Alan Carlin’s report. I’ll have more on this soon.]
[Update, July 7: I’ve added a comparison of the “updated” chart of global temperature projections and observations given by Carlin, and the original found in the IPCC Fourth Assessment Report (AR4). As well, an ironic twist to Steyn’s quote from Carlin is noted.]
A new uproar in the blogosphere has broken out over the supposed “suppression” by the EPA (Environmental Protection Agency) of an internal review of the EPA’s proposed endangerment finding on greenhouse gases. The review purported to show that the latest “research” calls into question the scientific consensus on climate change. It turns out that the report, written by Alan Carlin, with assistance from John Davidson, of the EPA’s National Center for Environmental Economics, is drawn heavily from the contrarian blogosphere, especially Ken Gregory of the Calgary-based “astroturf” group Friends of Science.
And in one case, a lengthy “analysis” of a recent peer-reviewed paper has been lifted, without attribution, straight out of World Climate Report, the climate “news” blog run by uber-contrarian Patrick Michaels.
[Update, June 29: In the immediately subsequent post, I’ve now established that the Carlin report’s central premise, along with four key sections, came directly from a November, 2008 World Climate Report blog attack on the EPA proposed endangerment finding on greenhouse gas emissions.]
