Global warming making blizzards worse?

"We’re on the verge of another historic blizzard, with as much as two or three feet of snow expected in parts of the Northeast. Already, the press is throwing around terms like “Snowmageddon” to describe what’s coming. Next comes politics: Whenever the East Coast sees an extreme snow event, the weather is perfect for snow trolling – e.g., trying to use one cold event to refute a warming climate trend.

In this case that’s particularly inappropriate, though, because if anything, extreme snowfall may actually be enhanced by global warming. I know it sounds counterintuitive, but remember that even in a warming world, our hemisphere will still spend part of the year tilted away from the sun, with shorter days and colder temperatures — and winter storms.

The question scientifically, then, is what happens to those storms in a warmer world. So let’s examine what science can say about that question.

Technically, the storm about to slam the Northeast is called — that’s right — a nor’easter. What’s special about these storms is that they draw their energy from a temperature clash between freezing Arctic air on the one hand, and warmer Gulf Stream waters on the other."
