Thompson et al [1993] on Dunde

Sep 18, 2005 – 2:10 PM

Thompson’s Dunde ice core is an extremely important proxy in multiproxy studies. There has been an increase in dO18 levels in the 20th century. Whether this is a proxy for temperature is not at all obvious on physical grounds. The relationship between dO18 and temperature in monsoon ice caps is opposite to that of polar […]

Science Editorial

Aug 27, 2005 – 10:35 AM

Science has recently weighed in with an editorial in which the editor of Science, Donald Kennedy, stated that he is “outraged” by the Barton Committee inquiring into processes for due diligence and disclosure in connection with science being applied for large-scale public policy. I thought that people might be interested in an account of my […]

Puruogangri (2000)

Jul 29, 2005 – 11:12 AM

I was collating information on Thompson’s archiving of ice core information and noticed something interesting on the Puruogangri glacier in the Himalayas drilled in 2000 and still unarchived. (Thompson is one of the 20 wise men who recently weighed in with the Barton Committee on behalf of MBH.) In addition to not being archived, I […]

Quelccaya Accumulation

Feb 10, 2005 – 6:33 PM

Quelccaya accumulation are 2 of only 14 proxies in MBH99. I think that it was the very first Mann proxy series that I posted about (circa May 2003), as the underlying data looked very strange when plotted. Hans Erren has posted up an interesting analysis which both explains the strange appearance of the series as […]

Thompson # 1: Inconsistent Dunde Versions

Feb 6, 2005 – 4:19 PM

The Dunde (Himalayas) ice core is a staple of multiproxy studies (MBH98, Crowley and Lowery [2000], Yang et al [2002] used in Jones and Mann [2003], Jones and Mann [2004]). It was one of 4 series that contributed the only hockey-stick-ness to the results – see here . Although the core was taken over 17 […]
