NASA on the snow and the mild winter – AGW not mentioned

WUWT
"2012′s relatively light snowfall is the result of two atmospheric processes, according to climatologist Bill Patzert of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. One is the La Niña conditions in the Pacific, which result in less moist air crossing the continental United States. The other is a strong Arctic Oscillation that keeps cold arctic air around the North Pole and away from more southern latitudes."
