It depends on how you measure coldest winter ever; average temperature, degrees below zero, etc. But no matter how you slice it, 2013-14 is going to go down as the coldest winter in decades, certainly in the lives of my daughers, to this point, who are 18 and 20. And no, I'm not suggesting one brutal winter is evidence that global warming isn't real.
But it's the epitome of chutzpah for the global warming crowd to declare that weather "extremes" such as a bitterly cold Wisconsin winter prove their case! There has been no appreciable global warming since 1998. Should it be shocking to anyone that such a "pause" as the global warming crowd calls it, would see winters return to the kind I grew up with in Wisconsin. Apparently it's shocking to them.
