This is a very interesting case of blogosphere ecology. A crime occurred and like ants repelling invaders in their nest the blogosphere dissected the evidence and found a suspect. That the moron went and confessed to an indictable crime was obviously a bonus.
I suspect that a part of it was forensics pointing to him and the confession is a carefully drafted damage limitation device written by his lawyers. Trying to tough it out in the face of the evidence would have been worse.
It's my guess that he didn't act alone and there was connivance with some of the sites prior to publication of the documents, hence the short time between receiving the material and publishing it.
The stupidity was to believe that such a scheme wouldn't unravel very quickly, with the prospect of federal charges and damages for libel. Our very own Beeb would appear to be exposed and they haven't been doing anything to mitigate their exposure.
The science is clear, CO2 driven warming is rubbish. But there's a lot of clearing up to do and pinning accountability firmly where it lies will be an enormous battle.
The cant will probably change to sustainability, or energy security. A few of the names will be changed and every effort will be made to continue with the impositions, taxes, non-jobs and scams.
