The year 2012 brought the warmest year on record in the U.S.A. as well as the smallest Arctic ice pack. At some point one might guess that progressive atmospheric warming, and warming of the Arctic Ocean will bring accelerated ice pack melting, as in ice covering a mud puddle that is slow to defreeze one day and increases it melting in time. Maybe it's this year, maybe next decade yet that increased melting rate may develop.
