The Northeast snowstorm of 2010 by satellite view

The Northeast snowstorm of 2010 by satellite view. Gosh, a December 28th satellite photo of the snowstorm in the Northeastern US, the “Image of the Day” at the NASA Earth Observatory website, must mean that Global Warming is a fraud! Just ask Anthony Watts.

Jeff Masters includes it with his top US weather events of 2010 and makes this insightful comment (italics mine):

The Northeast has seen an inordinate number of top-ten snowstorms in the past ten years, raising the question of whether this is due to random chance or a change in the climate. A study by Houston and Changnon (2009) on the top ten heaviest snows on record for each of 121 major U.S. cities showed no upward or downward trend in these very heaviest snowstorms during the period 1948 – 2001. It would be interesting to see if they repeated their study using data from the past decade if the answer would change. As I stated in my blog post, The United States of Snow in February, bigger snowstorms are not an indication that global warming is not occurring. The old adage, “it’s too cold to snow”, has some truth to it, and there is research supporting the idea that the average climate in the U.S. is colder than optimal to support the heaviest snowstorms. For example, Changnon et al. (2006) found that for the contiguous U.S. between 1900 – 2001, 61% – 80% of all heavy snowstorms of 6+ inches occurred during winters with above normal temperatures. The authors also found that 61% – 85% of all heavy snowstorms of 6+ inches occurred during winters that were wetter than average. The authors conclude, “a future with wetter and warmer winters, which is one outcome expected (National Assessment Synthesis Team 2001), will bring more heavy snowstorms of 6+ inches than in 1901 – 2000.” The authors found that over the U.S. as a whole, there had been a slight but significant increase in heavy snowstorms of 6+ inches than in 1901 – 2000. If the climate continues to warm, we should expect an increase in heavy snow events for a few decades, until the climate grows so warm that we pass the point where winter temperatures are at the optimum for heavy snow events.
