Global Warming and Snowstorms: Communication Nightmare, or Opportunity?

The Union of Concerned Scientists, a group I greatly admire, has held a press conference (with attendant media coverage) to air an argument that is already quite intuitive to me, but is probably precisely the opposite for others: Namely, that global warming could mean more mega-snowstorms, of the sort North America has seen in the past several years.

On a physical level, the case is sublimely simple. One of the fundamental aspects of global warming is that it increases the amount of moisture in the atmosphere, because warmer air holds more water vapor. From there, it’s a piece of cake—more snow can fall in snowstorms than before.
