Allegedly powerful warming blanket of CO2 goes AWOL again

Fresh arctic air will spread over the East today, leading to more lake-effect snow downwind of the Great Lakes. Record lows will be challenged across the South tonight.

A reinforcing shot of chilly air is pouring across the eastern half of the nation in the wake of a cold front. The cold will keep high temperatures below freezing over the interior Northeast and 10 to 20 degrees below normal across the South today.
