Last week in a Congressional hearing, John Holdren, the president’s science advisor, characterized me as being outside the “scientific mainstream” with respect to my views on extreme events and climate change. Specifically, Holdren was responding directly to views that I provided in Senate testimony that I gave last July (and here in PDF).
To accuse an academic of holding views that lie outside the scientific mainstream is the sort of delegitimizing talk that is of course common on blogs in the climate wars. But it is rare for political appointee in any capacity — the president’s science advisor no less — to accuse an individual academic of holding views are are not simply wrong, but in fact scientifically illegitimate. Very strong stuff.
Given the seriousness of Holdren’s charges and the possibility of negative professional repercussions, via email I asked him to substantiate or correct his characterization, to which he replied quite quickly that he would do so in the form of a promised follow-up to the Senate subcommittee.
Here is what I sent him:
Dear John-
I hope this note finds you well. I am writing in response to your characterization of me before the Senate Environment and Public Works Committee’s Subcommittee on Oversight yesterday, in which you said that my views lie “outside the scientific mainstream.”
This is a very serious charge to make in Congressional testimony about a colleague’s work, even more so when it comes from the science advisor to the president.
The context of your comments about me was an exchange that you had with Senator Sessions over my recent testimony to the full EPW Committee on the subject of extreme events. You no doubt have seen my testimony (having characterized it yesterday) and which is available here:
http://sciencepolicy.colorado.edu/admin/publication_files/2013.20.pdfYour characterization of my views as lying “outside the scientific mainstream” is odd because the views that I expressed in my testimony are entirely consonant with those of the IPCC (2012, 2013) and those of the US government’s USGCRP. Indeed, much of my testimony involved reviewing the recent findings of IPCC SREX and AR5 WG1. My scientific views are also supported by dozens of peer reviewed papers which I have authored and which have been cited thousands of times, including by all three working groups of the IPCC. My views are thus nothing if not at the center of the “scientific mainstream.”
