Probably same thing I'd say. Scientists don't agree on global warming. Our understanding of weather patterns is still too young to really confirm a thing called global warming. as recently as 1900, no one knew what trade winds were, and only Cuba had a decent handle on hurricane patterns. You assume that everyone but Palin believes in this great "tragedy" (a.k.a. scam) called Global Warming.
Personally, I think agree with the scientists who say that a lot of what we are seeing is likely just a cyclical weather pattern.
The only world leader global warming issues I'm concerned about are North Korea's wacko leader and Iran's terrorist president more than once declaring how they'd like to use nuclear weapons against Israel and America.
That's the key issue at hand.
