climate-cover-up

There has been no shortage of harumphing right wingers willing to spread PR manufactured talking points about the stolen CRU emails, quickly leaping to the conclusion that global warming is a “hoax.”

Kevin Grandia at DeSmog Blog regularly debunks the well-funded PR campaigns that promote this kind of crap, and he did some actual reporting.  He contacted Dr. Michael Mann for clarification, whose name appears in some of the emails and whose graph was used in Al Gore’s “Inconvenient Truth.”  Mann’s quote was widely disseminated by wingnutia as proof that “truth doesn’t matter”:

“Perhaps we’ll do a simple update to the Yamal post. As we all know, this isn’t about truth at all, its about plausibly deniable accusations.”

Mann’s response:

This refers to a particular tree-ring reconstruction of Keith Briffa’s.

These tree-ring data are just one of numerous tree-ring records used to reconstruct past climate.  Briffa and collaborators were criticized (unfairly in the view of many of my colleagues and me) by a contrarian climate change website based on what we felt to be a misrepresentation of their work.

A further discussion can be found on the site “RealClimate.org” that I co-founded and help run. It is quite clear from the context of my comments that what I was saying was that the attacks against Briffa and colleagues were not about truth but instead about making plausibly deniable accusations against him and his colleagues.

We attempted to correct the misrepresentations of Keith’s work in the RealClimate article mentioned above, and we invited him and his co-author Tim Osborn to participate actively in responding to any issues raised in the comment thread of the article which he did.

We’re looking forward to having DeSmog Blog founder James Hoggan on with his book, The Great Climate Coverup on the December 6 book salon.  In the mean time, check out DeSmog Blog for more sanity in a world of Exxon-funded “expert” nonsense about the “climate change” emails.
