Global sea ice extent finished the year at 1.69 million sq km above the 1981-2010 average. This equates to 8.2% above normal. During 2014, sea ice extent has been above normal for 245 days, at an average of 295,000 sq km.

Antarctic ice continues to blow away all records, beating the previous end of December level set in 2007 by 233,000 sq km. This is particularly significant from an albedo point of view, as it is mid summer down under at this time of year.

In contrast, ice extent in the Arctic has changed very little in the last decade as far as December is concerned.
