Northern Hemisphere winter snow extent was the second highest on record, at 52,166,840 km2. This was only topped by the second week in February, 1978 at 53,647,305 km2. Rutgers has kept records continuously for the last 2,227 weeks, so being #2 is quite an accomplishment.
According to Rutgers University data through mid February, Northern Hemisphere winter snow extent has been increasing at a rate of over 100,000 km2 per year.
As discussed on WUWT, the implication is that Northern Hemisphere snow cover has only extended this far south one other time, since Rutgers University started keeping records. Additionally, North American snow extent broke its all time record last week. Canada is normally completely covered with snow in the winter (except for Olympic venues) so the implication is that the US had more snow last week than has been seen in at least the last 44 years.
Two of the fundamental precepts of global warming theory are that the tropics are supposed to expand, and the Arctic is supposed to warm disproportionately and shrink.
