global warming models predict extreme snow events

The piles of snow blanketing the mid-Atlantic states have inspired global warming deniers in politics and the media to gleefully declare the demise of global warming...and a number of great comic responses, like this one by Jon Stewart:

Comedy aside, folks, heavy -- even apocalyptic snow falls -- are predicted by global warming theories. This is not a case (as suggested by folks like Glen Beck) of proponents of global warming seizing on every passing weather condition as it occurs and declaring it a result of global warming. The likelihood of increased extreme snow fall events arising from global warming have been predicted well in advance of this years snowmaggedeon, as the following excerpt from an article in a referred scientific journal supports:

“To assess possible future snowstorm conditions, the relationships of the storm frequencies to seasonal temperature and precipitation conditions, both estimated to undergo future changes, were defined for 1901–2000 using data from 1222 stations across the United States. Results for the November–December period showed that most of the United States had experienced 61%–80% of the storms in warmer-than-normal years. Assessment of the January–February temperature conditions again showed that most of the United States had 71%–80% of their snowstorms in warmer-than-normal years. In the March–April season 61%–80% of all snowstorms in the central and southern United States had occurred in warmer-than-normal years. The relationship of storm incidence to precipitation in all three
2-month periods of the cold season showed that 61%–85% of all storms occurred in wetter-than-normal years. Thus, these comparative results reveal that a future with wetter and warmer winters, which is one outcome expected (National Assessment Synthesis Team 2001), will bring more snowstorms than in 1901–2000. Agee (1991) found that long-term warming trends in the United States were associated with increasing cyclonic activity in North America, further indicating that a warmer future climate will generate more winter storms.” page. 1149
