Artic Ice Melt caused by Global -- blowing?

According to NASA, the cause of the Artic Ice melt is not a rapid rise in temperature, but rather an unusually strong wind (as reported by AccuWeather's Global Warming Gang):

Anyway, in a news release from NASA Monday, a group of scientists have determined that unusual winds caused the rapid decline (23% loss) in winter perennial ice over the past two years in the northern hemisphere. This drastic reduction is the primary cause of this summer's fastest-ever sea ice retreat in recorded history which has lead to the smallest extent of total Arctic coverage on record.
"Unusual atmospheric conditions set up wind patterns that compressed the sea ice, loaded it into the Transpolar Drift Stream and then sped its flow out of the Arctic," said Son Nghiem of NASA's Jet Propulsion Laboratory and leader of the study. When that sea ice reached lower latitudes, it rapidly melted in the warmer waters.

Of course, we can always blame the wind on Global Warming. I wonder if NASA will lose it's funding now. :-)
