Heavy Amounts of Snow=Climate Change Fraud. Now that's a logical conclusion.

Unusually heavy snowfall and bad weather is proof to climated change deniers that Al Gore was wrong. The same Al Gore who created global warming and the internets. Enjoy the clip below, featuring commentary from Stepen Colbert, Rachel Maddow and the Daily Show.

The New Republic had this to say about the climate change "see, it's snowing" deniers.

Washington D.C.'s getting slammed by record snowfall right now, which means that in addition to unplowed roads and Mad Max-style scenes at Safeway, we also have to suffer through a flurry of Al Gore jokes and Republicans snorting about how this proves global warming is all fake. A more thoughtful reply comes from meteorologist Jeff Masters, who explains how massive snowstorms in the Northeast are, in fact, quite consistent with a steadily warming world:
There are two requirements for a record snow storm:

It's not hard at all to get temperatures cold enough for snow in a world experiencing global warming. According to the 2007 Intergovernmental Panel on Climate Change (IPCC) report, the globe warmed 0.74°C (1.3°F) over the past 100 years. There will still be colder than average winters in a world that is experiencing warming, with plenty of opportunities for snow.

The more difficult ingredient for producing a record snowstorm is the requirement of near-record levels of moisture. Global warming theory predicts that global precipitation will increase, and that heavy precipitation events--the ones most likely to cause flash flooding--will also increase. This occurs because as the climate warms, evaporation of moisture from the oceans increases, resulting in more water vapor in the air.

According to the 2007 Intergovernmental Panel on Climate Change (IPCC) report, water vapor in the global atmosphere has increased by about 5% over the 20th century, and 4% since 1970. This extra moisture in the air will tend to produce heavier snowstorms, Meanwhile, it's worth noting the U.S. Global Change Research Program actually predicted stronger winter storms for the Northeast, in its 2009 report on potential climate-change impacts for the United States:
