George Monbiot is getting in on the game now. Ok, I admit, emailed him about it - but was surprised and pleased that he picked it up so enthusiastically.
The tactic seemed to work well in terms of putting Ebell on the defensive. Of course my original hope was that the bets would establish what the range of beliefs actually was, but so far not a single sceptic has come forward to disagree with the standard (IPCC) view.
Sooner or later the denialists might decide that it is worth taking on a few losing bets, just to avoid looking dishonest. I just hope I can get a slice of the cash when they do.
