Lonnie Thompson, senior research scientist at Ohio State University’s Byrd Polar Research Center, and his colleague Paolo Gabrielli, have just been awarded a three-year $588,000 grant from the NSF’s Division of Atmospheric and Geophysical Sciences “to assess the human impact on the chemical characteristics of the glaciers in the Himalaya and the Tibetan Plateau from […]
Michael Mann’s new book, The Hockey Stick and the Climate Wars, discusses my comment [SMc note - this post is by Hu McCulloch] , “Irreproducible Results in Thompson et al., ‘Abrupt Tropical Climate Change: Past and Present’ (PNAS 2006),” that was published in 2009 in Energy & Environment. My comment pertained to an article by […]
One of the most persuasive images in the global warming debate is a graph that Al Gore describes in his An Inconvenient Truth as “Dr. Thompson’s thermometer.” According to Gore, this graph is based on oxygen isotope ratios from ice cores collected by Lonnie Thompson and his colleagues, and provides “the most definitive” independent confirmation […]
A CA reader sent me an email, noting the following entry in minutes of a meeting. M Loso inquired about Lonnie Thompson’s ice core data. These data are not presently available but will be investigated by Caspar. This comment is minuted in a meeting of PIs leading up to Kaufman et al 2009 – a […]
In Al Gore’s movie and book An Inconvenient Truth, he presents a graph which he identifies [in the book] as “Dr. Thompson’s Thermometer.” Gore attributes this graph to the ice core research of Lonnie Thompson, and says [in the book] that it provides independent evidence for the validity of the “Hockey Stick” temperature reconstruction of Michael Mann […]
Jud Partin observed yesterday that a “fantastic new record” had been recently (early Nov 2008) published from Wanxiang, China. Zhang et al report that their new record is “broadly similar” to the reconstructions of Esper, Mann and Jones 2003 and Moberg as follows: The Wanxiang record, with a d18O range of ~1.3 per mil (‰) […]
There’s not much in climate science that annoys me more than the sniveling acquiescence of government bureaucrats in Lonnie Thompson’s flouting of data archiving policies. To his credit, Thompson has collected unique data. To his shame, Thompson has failed to archive data collected as long as 20 years ago. This would be bad enough if […]
In 2002, Lonnie Thompson drilled a 460 meter ice core in a col between Mounts Bona and Churchill in Alaska. As of October 2003, they had analyzed over 5600 samples and concluded that the core covered approximately 2500 years. A presentation was made at AGU in December 2004. The data was not discussed in IPCC […]
I’ve been trying since 2003 to get detailed sample information from Lonnie Thompson on his tropical ice cores, some drilled 20 years ago. I reported on my most recent effort on Apr 19, 2007 under PNAS policies here. Thompson has once more obfuscated a journal by falsely telling them that everything already is archived (without […]
Al Gore’s hockey stick version (page 65 of the book “An Inconvenient Truth“) is taken from one of the many conflicting versions of Lonnie Thompson’s ice core data. Now there is an ongoing controversy about whether Thompson’s data is a temperature or precipitation proxy, with pretty much every other scientist except Thompson now viewing the […]
