Climate scientists have long pointed to the Southwest as one of the places in the U.S. that is most vulnerable to global warming impacts, especially drought. And if there's one thing that even climate denialists don't dispute, dry things burn.

Bill Gates is a relative newcomer to the fight against global warming, but he's already shifting the debate over climate change.

One of the big questions in the climate change debate: Are humans any smarter than frogs in a pot? If you put a frog in a pot and slowly turn up the heat, it won't jump out.
