Overall, ice coverage is well above what it was in 2012 (the lowest September extent since 1979) and many years since:
metmike: Actually the Arctic Sea Ice is ABOVE the last 4 years. Multi year ice is near the lows.

Antarctic sea ice well above average.

Very much related to this is the current La Nina signature in the Pacific which correlates to temporary global cooling.
The modest global cooling period 1950's-70's featured the most La Nina's in the last century and an increase in Arctic sea ice(though measurements are sparse)

This also correlates to more hurricanes in the East/Northeast.
The record years of 1954/55 were during the long lived 1954-1957 La Nina and modest global cooling.
