I've lived in the DC area for a little over two years, and haven't seen more than an inch of slush, much less snow, in my time here. Everyone I talk to says this is the most snow they've seen in 20 years.
And of course, the irony of the whole thing is that President Obama is flying back from the Copenhagen summit on global warming.
So the question is, how unusual is the snowfall?
Well, according to the New York Times:
Officials in Washington said the storm was likely to produce the area’s heaviest snow since February 2003, when about 16 inches fell on the region.2003 was also the sixth warmest year on record. 2009 is tied for the second warmest. The moral of the story is, heavy snowfall can occur even in the presence of global warming. Don't let the weather fool you.
