Do you really believe in climate change? Gambling and global warming

[UATrewqaz]

An interesting thing I heard in the news recently. Some guy challenged Al Gore to a 10K wager (10k fight yo?) for charity regarding some of his climate change predictions.

The guy is a professor and the story is here (warning, fox news link, try not to go insane)

And someone else pondered, with all these gambling websites out there where you can wager on crazy things (reality tv shows, American Idol, how many iPhones will be sold the first week, etc.) what if you put up lines on some of the global warming predictions?

Wouldn't such an exercise be pretty useful in determining whether or not the advocates of such predictions actually believe they will occur?

What sort of line would you want or need before committing alot of money? (I know it would depend on the particular predicition in question)
