Explaining our warm eastern winter

There's a good post on RealClimate titled "El Nino, Global Warming, and Anomalous U.S. Winter Warmth" that says that the unusually warm winter this year should neither be so simply attributed to global warming, nor to El Nino. As they note:

Peculiar weather precipitates immediate blame on global warming by some, and equally immediate pronouncements by others (curiously, quite often the National Oceanic and Atmospheric Administration in recent years) that global warming can't possibly be to blame. The reality, as we've often remarked here before, is that absolute statements of neither sort are scientifically defensible. Meteorological anomalies cannot be purely attributed to deterministic factors, let alone any one specific such factor (e.g. either global warming or a hypothetical long-term climate oscillation).
