I think the sense of the third floor (the air, ocean and ice groups) at AGU has shifted dramatically since the CRU hackings. Most people understand that conventional scientific comity in the face of impending disaster at some point becomes counterproductive. In any case it seems unlikely to protect you from unfair attacks anyway. So, yeah.
Slate has an excellent piece by Jonathan Mingle reporting from AGU on this subject.
That’s the sound of serious-minded scientists fretting out loud to the rest of us that the earth is indeed f**ked, unless we get our s**t together. More and more are willing to risk professional opprobrium to drive that message home.
