I have previously blogged about the record low (since satellite measurements began) for Arctic sea ice in 2007, and some of the contributory factors, here, here and here. The record high for sea ice coverage in the Antarctic received little or no media attention.
So what is the current situation? NASA’s earth observatory has an Arctic sea ice update here:
“After record retreat in September 2007, Arctic sea ice had been making a slow winter recovery. Mean sea ice extent remained at record-low levels in October 2007, but beginning in late October, sea ice grew by more than 150,000 square kilometers (about 58,000 square miles) per day for about 10 days—the fastest regrowth observed in the satellite record. Despite this rapid growth, sea ice extent remained below normal for November, though it was not a record low.”
According to the University of Illinois website The Cryosphere Today, sea ice coverage for January 31 2008 is about 900,000 square kilometers below average for the Arctic and about 500,000 square kilometers above average for the Antarctic. Compare past Arctic sea ice coverage from 1980 onwards with the present at the same time of the year here.
