Not much of a debate really, it's a private meeting;
$1:
Both Redford and Gore are scheduled to take part in a private session discussion on "the future of climate regulatory mechanisms and their impact on business" while in Davos on Thursday.
As such, they'll both claim victory no doubt.
Still, if it was a real debate, I'd put my money on Redford. With her background in law and the UN, she'd tear Gore a new one.
