Since it is a subject dear to my heart, I thought you’d like to know that today is International Polar Day, part of the IPY.
The IPY website now has a load of snazzy links to lots of useful stuff about sea ice, here.
Update on current sea-ice extent: the latest NSIDC press release is here. It looks as if the past week has seen the minimum, though as the release points out, it’ll be a couple of weeks before this can be confirmed. On scale of losses this year, the NSIDC says that the anomaly compared to the previous lowest figure is the size of Texas and California combined, or five UKs.
For the full horror story, the animation at the bottom, of minima from 1979-present, is the eye-opener.
