Steve McIntyre has posted his letter to David Karoly regarding Karoly’s book review, covered by WUWT here. Karoly responds with a suggestion he’s been given a ‘legal threat’. After reading McIntyre’s letter, I’m reminded of the non-existent death threats towards climate scientists in Australia…because I sure can’t find any legal threat from Steve. Maybe David Appell can use his superior death threat knowledge to pinpoint this. /sarc

=============================================================

I learned of this article from a CA reader here. Karoly’s slagging seemed particularly cheeky given the role of Climate Audit in the recent withdrawal of Gergis et al 2012, of which Karoly was a coauthor and this prompted me to respond:

Dear Dr Karoly,

It has come to my attention that you have made the following untrue and defamatory statement about me (https://www.australianbookreview.com.au/feature-articles/1063-343-features-karoly):

Commentators with no scientific expertise, ranging from politicians such as Republican congressman Joe Barton from Texas, Virginia Attorney General Ken Cuccinelli, or Republican Senator James Inhofe from Oklahoma, to blog writers Stephen McIntyre and Marc Morano, have repeatedly promulgated misinformation and sought to launch formal investigations into Mann’s research, claiming professional misconduct or worse, even though it had been peer reviewed and confirmed by other scientists

I try to write accurately and, to my knowledge, have not “promulgated misinformation” about Mann’s research, let alone done so “repeatedly”. Together with coauthor Ross McKitrick, I published criticism of Mann’s work in the same peer reviewed journal as Mann et al 1999. We published these criticisms in good faith. In my opinion, not only have the specific criticisms not been refuted in subsequent commentary, but, if anything, our findings have been confirmed even by adversaries. For example, our finding that the verification r2 of the Mann et al reconstruction was not only not significant but ~0 was confirmed by the very adversarial Wahl and Ammann article. While some topics remain in controversy, I note that neither the National Research Council Report nor the Wegman Report in 2006 identified any errors in our work; that the Wegman Report, in particular, strongly endorsed our work and that Gerald North, the Chairman of the National Research Council report, when asked, stated that he agreed with the conclusions of the Wegman Report. While such endorsements do not ensure that our findings are correct (though I believe our findings to be correct), the failure of these panels to explicitly identify errors speaks strongly against your allegation of promulgating “misinformation”.

Obviously, I have also commented extensively at Climate Audit, but always try to be accurate and to correct any errors when pointed out. I request that you either provide me forthwith with specific examples of the “misinformation” that you allege that I’ve promulgated or withdraw the allegation with an apology.

Your recent experience with Gergis et al 2012 should have demonstrated to you that “peer review” by an academic journal is hardly a guarantee of the validity of results, let alone assurance that authors have even implemented their claimed methodologies. I further observe in this connection that your public statement in connection with the withdrawal of Gergis et al 2012 did not include any acknowledgement of Climate Audit’s role in identifying the error in Gergis et al. Your public statement was:

An issue has been identified in the processing of the data used in the study, “Evidence of unusual late 20th century warming from an Australasian temperature reconstruction spanning the last millennium” by Joelle Gergis, Raphael Neukom, Stephen Phipps, Ailie Gallant and David Karoly, accepted for publication in the Journal of Climate. The authors are currently reviewing the data and methods. The revised paper will be re-submitted to the Journal of Climate by the end of July and it will be sent out for peer review again.

It is evident that the error had not been discovered by the authors or by peer reviewers at the time that Climate Audit raised the issue of screening procedure in Gergis et al on May 31, 2012 here, a discussion that quickly identified the error. I do not believe that you identified the error independently of the discussion at Climate Audit and accordingly it is my opinion that your failure to acknowledge Climate Audit in your public statement constitutes the use of ideas and/or work derived from Climate Audit without the appropriate acknowledgement.

Yours truly,

Stephen McIntyre
