Once again, three climate activists who are not terribly good at debating agreed to participate in a decidedly unscientific format against people who mostly make stuff up. And what a shock, it had a bad outcome -- although this one seems to be partly a result of gaming the vote as much as anything else.
In 2007, it was the now-infamous climate science debate, broadcast by NPR on the proposition "Global warming is not a crisis." The pro-science side lost to the anti-science make-stuff-up side (Michael Crichton, Richard Lindzen, Philip Stott) on that one.
So you can imagine what happened when the debate proposition moved over to economics, "Major Reductions in Carbon Emissions Are Not Worth the Money" -- especially with the 'pro' (i.e. delayer) side handled by three world-class economist-loving liars make-stuff-uppers: Bjorn Lomborg, Peter Huber, and Stott (details here, transcript here [PDF] and, for true masochists, NPR audio here).
(Note No. 1 to all pro-climate-action debaters: It is very hard to win a staged debate with people who make stuff up. It is next to impossible to do so if they are skilled debaters. And you are guaranteed to lose if it isn't a one-on-one debate. Why? The only way to out-debate somebody who makes stuff up is to call them out on it. And if they keep doing it, you have to keep calling them out. Even the most skilled debater has difficulty publicly questioning the honesty and integrity of opponent again and again (which is why you rarely see anyone attempt it). But you'll never convince an audience that multiple 'experts' are making stuff up.)
The final result of this absurdly unscientific and meaningless activity was preordained. It was also so bogus that even the organization that put on the pointless debate actually acknowledged in its own press release (here) that part of the audience (the conservatives, of course) gamed the system:
