The latest battle over the “hockey stick” has taken quite a turn, one that may finally lay to rest all the absurd claims of its demise made by contrarians (not to mention apparently libelous accusations of scientific malfeasance). In previous posts, we discussed climate blogger Steve McIntyre’s scurrilous accusations of “cherrypicking” against UK dendrochronolgist Keith Briffa, and summarized a a quick technical critique of McIntyre’s work by a dendrchronologist known as Delayed Oscillator.
Now comes new evidence that McIntyre’s accusations were completely false. And not only that, one of the Russian researchers who actually control the raw tree-ring data that McIntyre was mistakenly hounding Briffa for, has apparently confirmed that utilization of a newer more complete Yamal data set has no substantial effect on Briffa’s Yamal temperature reconstruction.
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.
