Whoa! Hold on a sec - so there's fuck all sea ice in the summer anyway? 7.7 sq km is a circle with a radius of 1.6km, you could walk across it in an hour. Is this right?the guardian said:The new figures show that sea ice extent is currently down to 4.4m square kilometres (1.7m square miles) and still falling. The previous record low was 5.3m square kilometres in September 2005. From 1979 to 2000 the average sea ice extent was 7.7m square kilometres.
