t scientists should probably ask themselves why there is still such a large cohort of “deniers” as they like to call them, who are adamant that anthropogenic climate change is a scam What makes you think they haven't? "Jennifer Marohasy, " Oh, good; I was afraid she would never show up. Thanks. “Our new technical paper … will likely be ignored,” she writes at The Spectator Australia. She should be so lucky. Marohasy Mess Up Among the things that bother Eli, and there are myriad, is not understanding that because proxy reconstructions are calibrated by using instrumental records they by necessity ASSUME Mike's trick, extending the proxy by use of instrumental data. In fact, the instrumental data is more accurate in the period where they overlap, because the proxys are scaled to it. Thus, the instrumental record used for the calibration should always be shown. Moreover, IEHO, the usable instrumental records (properly homogenized of course) in the area where the proxy is sampled should be the ones used to scale each proxy individually. Something that either does not appear to be much done or at least not much noted. No matter. Anyhow, Jeniffer Marohasy and accomplice John Abbot have published a paper in a soon to be former Journal, GeoResJ, of which it could be said that it is Elsevier and it is history GeoResJ will be discontinued from January 2018 and is closed to new submissions. We would like to express our sincere thanks to the authors, referees, editors and editorial board members who have contributed to the journal over the past few years.As to Jen and John, well Eli guesses that they have observed the profit that Judy Curry and Peter Webster are making, well they have set up their own long range weather forcasting service, one that Eli assumes will compete with the Farmer's Almanac and Piers Corbyn for James Annan's betting attention. They even have their own journal. Isn't the Internet wonderful. Frankly Eli is of the opinion that Curry and Webster are ahead in that game even tho the Bunny's opinion of the later two, is, well, limited. ATTP has published a comment on the Abbott Marohasy paper. Go there for details, but Eli wants to pick up on the Twitting. One of the fits from the AM paper were featured on Breitbart (friends don't link friends to Breitbart :(. It turns out that that was from Moberg 05 and various claims were undressed by the usual skeptics. Zeke was the first to notice, and he twitted the This new tree ring proxy reconstruction that Breitbart is claiming shows "global warming almost entirely natural" is missing something... pic.twitter.com/7FRYZEldA0 — Zeke Hausfather (@hausfath) August 22, 2017 which he later ammended to Here is what it would look like with 10-year average NH land/ocean temperatures appended to their Moberg record: pic.twitter.com/HdPaaTw4Ix — Zeke Hausfather (@hausfath) August 22, 2017 22 Aug Zeke Hausfather @hausfath Replying to @thirstygecko @ClimateOfGavin Ahh, fair enough. My spliced figure might be a bit skewed in that case as I assumed the paper was using a land-based proxy record. Follow Now Eli went and looked at Moberg 05 to find To calibrate the reconstruction, its mean value and variance were adjusted to agree with the instrumental record of Northern Hemisphere annual mean temperatures [19] in the overlapping period AD 1856–1979 (Fig. 2b).Ref 19 is Hemispheric and Large-Scale Surface Air Temperature Variations: An Extensive Revision and an Update to 2001 by P. D. Jones and A. Moberg the first two sentences of which are This study is an extensive revision of the Climatic Research Unit (CRU) land station temperature database that is used to produce a gridbox dataset of 5° latitude × 5° longitude temperature anomalies. but also included a land+ocean data merge and it looks like that is the one Moberg used. Gavin got an ear in pointing out that Abbott and Marohasy's time axis was off by ~ 35 years. That meant that their 20th century was really 1845-1965. As all know there has been a steep rise in global temperature since then. and fetched J. Marohasy out of the brian patch reject your false claims, and is inappropriate that u graft instrumental thermometer HadCRUT record onto proxy record — Jennifer Marohasy (@JennMarohasy) August 23, 2017 which is amusing in light of Fig. 2B from Moberg 05 POSTED BY ELIRABETT AT 11:09 PM rabett.blogspot.com
