I know this is old news, but I just found the youtubes of this debate. You will recall how Plimer declined to answer some very straightforward requests for evidence of a handful of his most egregious fabrications that George Monbiot put to him as a precondition of a debate. Well, not because Plimer decided to be forthcoming, the debate went ahead in December with no preconditions.
It can be viewed in three parts below.
If you don’t have time for it all (~24 minutes) I would recommend starting at part 2.
Is anyone impressed with Plimer’s evasivness. He might as well have just plead the 5th, and refused to answer on the grounds he might incriminate himself! Monbiot struck just the right tone, IMO.
