The global warming debate isn't likely to cool off anytime soon, with experts disagreeing about its causes, and even its existence.
What you hear about global warming can vary as much as, well, the weather.
One day, California Gov. Arnold Schwarzenegger is quoted saying: "We simply must do everything we can in our power to slow down global warming before it is too late. The science is clear. The global warming debate is over."
Another day, former Pennsylvania Sen. Rick Santorum says this: "Americans are coming to understand that global temperatures have actually cooled over the last 10 years and are predicted to continue cooling over the next 10."
