Several people have drawn attention to letters from the U.S. House of Representatives Energy and Commerce Committee to Mann, Bradley, Hughes, the director of the U.S. National Science Foundation and the chairman of the IPCC, which were posted up at the Committee website on Friday here.
The letters refer to the Wall Street Journal [this would presumably be the article of Feb. 14, 2005, in which Mann said that he would not be "intimidated" into releasing his algorithm, rather than the recent editorial], as well as to our articles. They have directed Mann, among other things, to produce his source code. In our E&E article, we pointed out several areas, where, in our opinion, MBH98 did not meet "full, true and plain disclosure" standards, which are routinely applied to securities offerings and promotions, e.g. the withholding of R2 and other verification statistics, the impact of the presence/absence of bristlecones (the CENSORED directory), the "editing" and misrepresentation of the Gaspé start date. Questions are asked specifically about these matters.
The questions are focussed on process, with particular emphasis on processes for validation and verification, issues which are obviously of interest to readers of this blog. The letters are well worth taking a look at.
