Arctic sea ice extent 2013 (brown line on NSIDC-image below) is more and more following the same path it did last year (dashed line), when extent reached a record minimum, and in 2007 (blue line), the previous record minimum.
Even more worryingly, sea ice is very thin, as the Naval Research Laboratory animation below shows; large areas with a thickness of 1 meter to zero persist close to the North Pole, as discussed in an earlier post; the image below, from the North Pole Environmental Observatory shows lots of water and that it's raining at the North Pole.
The above animation also shows the retreat of sea ice from the Kara Sea, north of Siberia, over the past 30 days.
As can be expected, high sea surface temperature anomalies show up in areas where the sea ice has retreated, as shown by the DMI image below.
Most worryingly, high methane readings appear over the Kara Sea, as shown on the image below.
