Something worth considering. We associate snow with cold, so it's tempting to see more and frequent snowstorms as disproof that the planet is warning. However temperature is only one of the constraints on snow. The other is moisture.
I have lived here in Boston over fifty years, and in the 60s and 70s the December climate was bitterly cold and *bone dry*. In recent decades there has been a marked tendency toward warmer AND wetter Decembers and Januaries, and thus frequent significant snow storms in December (almost unheard of) and January (rare until the 90s).
This storm was particularly intense, and in my town got two feet or more. This has happened on six prior occasions, once in 1888, and five times since 1969.
