In the Crossfire: Cold sparks climate skeptics

The bitter cold that a "polar vortex" is pushing into much of the United States is not just another winter storm. It's the coldest in 20 years in many areas, and breaking some records. Full story here.

How far below zero does it have to get to cool off the global warming debate?

Tonight Van Jones and Newt Gingrich host Crossfire with guests Navin Nayak, who wants climate change legislation and David Kreutzer, who's against it.

Besides the freezing cold weather, another topic on many Americans' minds is the college football BCS National Championship game where Auburn squares off against Florida State. Who do you think will win?
