Snow Panic a Growth Industry?

National Geographic indicates that winters like this past one (with two 2'+ snowfalls) -- 1-in-300-year events in the old days -- may become the norm.  Global warming, which you might think would prevent snowstorms, may actually cause them.  Not necessarily for the reason previously speculated here -- shutdown of the Gulf Stream -- but because warmer temperatures cause more moisture to be evaporated from oceans.
