The Quelccaya Update

Lonnie Thompson has done a much better job of archiving data for his recent update Quelccaya – see NOAA here – both in terms of information and promptness. Quelccaya is familiar territory for Thompson as it was the location of his first tropical ice cores (1983) and his first publication of this type. Thompson published […]

Lonnie Thompson’s Legacy

In my last post, I observed that Ellen Mosley-Thompson’s archiving record was even worse than that that of her husband, Lonnie Thompson, whose failure to adequately archive his ice core measurements has long been a subject of criticism at Climate Audit. In particular, I observed that Ellen had archived nothing from the 15 expeditions to […]

Lonnie and Ellen, A Serial Non-Archiving Couple

Recently, Geoffrey Boulton’s report and Nature editorial provided more pious language urging data archiving by hoarding scientists. As I mentioned in my initial comments on Boulton’s editorial, there have been many such pious pronouncements over the years without the slightest impact on, for example, the serial non-archiving couple of Lonnie Thompson and Ellen Mosley-Thompson, who, […]

Thompson Gets New NSF Grant

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 […]

Mann on Irreproducible Results in Thompson (PNAS 2006)

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 […]

Calibrating “Dr. Thompson’s Thermometer”

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 […]

Kaufman et al: Obstructed by Thompson and Jacoby

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 […]

Irreproducible Results in PNAS

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 […]

Five Monsoon O18 Series

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 (‰) […]

IPCC and the Dunde Variations

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 […]
