Man oh Man it's Cold Out!

This morning it's 21 degrees colder than yesterday.
How is that normal?
A week ago we almost hit 70 in December.
I like the warmth, but this is a little weird.
How is it that this has it nothing to do with global warming?
I feel like it's on the tip of everyone's tongue but nobody wants to admit it.
I guess the EPA really shouldn't bother with the Clean Air Act or the regulation of CO2. Even if Massachusetts wins it's not likely the people who work there (and more importantly who they work for) will do very much to begin with.
