“Also for your information, the original version of this post mentioned McIntyre (and linked to his posts) extensively. But prior to posting I decided to remove that, since McIntyre had already fully explored the ‘low road.’”
Can you clarify something: Are you saying you used McIntyre’s ideas, but removed any citations attributing those ideas to him because he was taking the low road? Or are you saying something different? Thanks.
[Response: All I “learned” from McIntyre’s “analysis” is that Marcott et al. had re-calibrated proxy ages, that McIntyre blamed the uptick on the re-dating process, and that he was happy to hint at the possibility of deliberate deception on the part of the authors. The references to McIntyre in my original version were to his insulting tone regarding this work, but I finally decided it was better to ignore that and comment on the science. It now seems that on the “dot earth” blog he chose to accuse me of having “shamelessly plagiarized” his ideas on why the exaggerated uptick occurs in the Marcott et al. temperature reconstruction. He’s wrong.
I didn’t read all his posts about the paper, for two reasons: first, there are so many, and I find them so full of sneering and thinly veiled innuendo that they’re sickening; second, there’s really very little to be learned from him. In my opinion he’s just not interested in understanding the science, he only wants to kill hockey sticks.
I’m hardly ignorant of the effect of station dropout (in this case, proxy dropout) on averaging temperature data, I’ve known about it since long before Marcott et al. was even published. If Steve McIntyre wants to claim that he identified proxy dropout as the reason for the extreme recent temperature uptick in the Marcott paper before I did, fine. It wouldn’t be the first time two different people had the same idea. I congratulate him on his insight. As for his assuming that I got the idea from him and didn’t credit him, it’s no surprise that he would assume the worst possible motives in others.
My opinion: perhaps if Steve McIntyre had been more careful in explaining himself, more interested in communicating reality than in demeaning the results, and less indulgent of his own sneering, people might refer to him rather than me when mentioning the impact of proxy droupout, and the “dot earth” blog might be referring to his posts rather than mine as “illuminating.”
Also my opinion: if Steve McIntyre were really interested in the science rather than just killing hockey sticks, he might have applied the “differencing method” himself and discovered that the uptick is still there (but reduced in size) when the impact of proxy dropout is dealt with, whether one uses the re-calibrated ages or the original published ones.
But that would require him actually to do some science.
Notice that I not only identified (quite independently) the reason for the exaggerated uptick, I also implemented a method to overcome that problem? Notice how I showed the result and compared it to Marcott’s reconstructions? Notice how I computed the result using both the re-calibrated and the originally published proxy ages? Notice how I did so for the same latitude bands as Marcott, and compared those too? Notice how I even did an area-weighting of those latitudinal results? Science.
Notice also that I disputed the reality of the exaggerated uptick in the Marcott et al. reconstruction without once even hinting that the authors had manipulated the data for nefarious purposes?
As for the differencing method, I didn’t credit the inventor (I don’t even know who it is) although I didn’t come up with that one independently. Perhaps McIntyre will accuse me of having “shamelessly plagiarized” that as well.]
