Quite astonishingly, Antarctic sea ice has set another record for maximum extent, beating the previous record of 19.513 million sq km, set on 21st September this year.
What makes the new record so astonishing is that it was set in October, on the 1st. Climatologically, the maximum extent is reached on 22nd September, so it is most unusual for the ice still to be growing 10 days later.
As at the 18th October, extent is still running at 998,000 sq km above normal.
With the Arctic ice running at 728,000sq km below normal, this means that global sea ice is 270,000 sq km above the 1981-2010 norm.
Global sea ice area is also above normal, as it has been for much of the year.
