One particular graphic that was popular on the Web on Tuesday showed the average snow cover during December, January and February. It showed that snow cover in the Northern Hemisphere was about 45.5 million square kilometers — at least 1 million square kilometers more than what it was in most of the 1990s.
“If you wanted to say that there’s no global warming, then, yeah, look at December, January and February,” said Kevin Trenberth, a distinguished senior scientist in the climate analysis section of the National Center for Atmospheric Research in Boulder, Colo. “But as soon as you look at March, April, May and June, you have a very different picture.”
What’s at play with the high winter snowfall, he said, is increased moisture in the air, which leads to bigger snowstorms. And that, says Trenberth, is not a result of colder air, but of warming ocean temperatures.

The high winter snow extent is due to cold air pushing the snow line further south. Trenberth is suggesting that snow in Florida is due to an increase in humidity? It doesn’t get much stupider than that.
