Watts Up With That?

According to the Rutgers University Global Snow Lab,
last month had the second greatest December Northern Hemisphere snow
cover since records were started in 1966.  Snow extent was
measured at 45.86 million sq. km, topped only by 1985 at 45.99 million
sq. km.  North America set a record December extent at 15.98
million sq. km, and the US also set a December record at 4.16
million sq. km.

This is not an isolated event for 2009, as can be seen in the graph
below.  Seventeen of the last twenty-one Decembers have had above
normal snow cover.

Nor is it an isolated trend for the month of December.
 January, 2008 was the second snowiest January on record, and six
out of the last eight Januaries have had above normal snow.

October, 2009 was the snowiest October on record in the US, and
sixth snowiest in the Northern Hemisphere.  Twelve of the last
fifteen Octobers have had above normal snow cover in the Northern
Hemisphere, similar to the pattern of the 1970s.

A favorite mantra of the global warming community is that reduced
snow cover will reduce the albedo of the earth and provide positive
feedback to global warming – causing additional warming.
 Clearly that is not happening, at least not during the October
through January time period.

2010 is also getting off to a fast start.  Most of Europe and North America is covered with snow, as is much of Asia.
