What followed was an email exchange that provides some insight into the mindset of the activist wing of the climate science community. Greenberg shared this exchange with me with the following message, published here with his permission:
Roger, Re my stirring experience of jousting with Mann, Ehrlich, and Rahmstorf: What a scurrilous bunch. My sympathy to you and anyone else who has to deal with them. They're gravediggers of science. Nature will soon publish my riposte and, I think, a disclaimer of any ties to me by the Marshall Institute. Below, my further exchanges with the low-life trio. Best regards, DanHere is Greenberg's email to Michael Mann that concludes the exchange, reproduced with his permisison:
Dear Professors Mann, Ehrlich, and Rahmstorf,If Michael Mann thinks that he has been treated unfairly by my decision not to publish his side of the exchange, I will be happy to post up his emails with his permission. Somehow I doubt that he will be as forthcoming as Greenberg. The repeated character assassination and behind-the-scenes attacks of a small segment of the climate science community gives the entire field a black eye, and it continues unabated. Greenberg is right, these guys could make apple pie and motherhood come under public suspicion.
Your correspondence concerning my review of Roger Pielke's book "Climate Fix" has provided me with a deeper understanding of the widespread public skepticism toward climate science. In your hands, apple pie and motherhood would come under public suspicion. Have you considered taking a remedial reading course? Can you comprehend the difference between a book reviewer's own beliefs and the reviewer's presentation of the beliefs expressed by the author of the book under review? Apparently not. Furthermore, your insinuation of an undisclosed relationship between me and a conservative think tank is preposterous. In 2006, I participated in a panel discussion sponsored by the Marshall Institute---as I have done with numerous other organizations, including the Brookings Institution, RAND, AAAS, and various academic societies and universities. Common practice for journalists. Nor did I, as you allege, write a report, or anything, for the Marshall Institute. The panel's words were transcribed and published by the Institute. I wrote nothing for them. You guys are the devil's gift to the Tea Party and other climate-change wackos.
Sincerely, Dan Greenberg
