In other words, the IOP statement came across as a typical piece of denialist crap.
After the statement was issued, push-back ensued from enraged IOP members and the media, and the institute began to "clarify" its way out of the pickle it found itself in. What eventually became clear was that the Institute's statement had been hi-jacked by members of its energy sub-committee, who managed to steer their document through the IOP's larger administrative structure and land it (the statement) on the desk of U.K. Science and Technology. Now Peter Gill, one of the the members of the energy sub-committee, and a known denialist, has spoken out, and while I don't take his account at face-value, this part--a letter from the IOP to members of the Energy sub-committee--seems straight-forward enough:
Following the meeting of the Science Board on 17 June 2010, it is with regret that I announce that the Energy Sub-group is to be disbanded, immediately. This, as you can imagine, is a direct consequence of the Climategate affair.
So, some retroactive justice, at least.
For another account of an organization (the American Physical Society) infiltrated and made to look silly by deniers, try this.
DC's piece is most interesting, as it presents strong evidence that knowledge of the IOP's statement was conveyed in advance (almost a month in advance, in fact) to climate change denier and swivel-eyed lunatic Christopher Monckton:
