Politically speaking, it won't happen. Global warming is inextricably bound up with the IPCC in people's minds. So much effort was expended on telling everyone that they had to believe the IPCC because it was a consensus of all the scientists in the world (what, you think you're smarter than all the scientists in the world?) that to come along now with "Did we say <i>that</i> consensus? We meant <i>this</i> consensus" can't possibly work.<p>I meant to post this the last time the subject came up, just for the record: it's beginning to look like the IPCC (and with it, perhaps, the entire issue) has hit its peak.
