'America is not a planet': Republicans resist climate change action at debate

Rubio says economy must come first as candidates address issue on CNN, as Christie rejects 'wild leftwing idea' that we can fix the climate alone

In an exchange that would have been all but unthinkable even four years ago, moderator Jake Tapper posed a question to Florida senator Marco Rubio and New Jersey Governor Chris Christie that quoted Reagan secretary of state George Schultz: "Why not take out our insurance policy and approach climate change the Reagan way?"

But despite the token question well into the third hour of CNN's GOP debate, no candidate was willing to endorse any possible solution.
