Interesting.
it appears that it was a ploy to attempt to discredit the Global warming deniers...Or at least have a little fun at their expense.
The truth is, this may be a breaking point in the whole argument...It shows that the true believers in global warming have room for a little comedy in their belief system...IE. The issue isn't so deadly serious that such a comedy routine would be blasphemy.
But we'll see how other believers handle the comedy.
