Arctic sea ice extent 2019-20 set to challenge record minimum of 2011-12

This years summer minimum ice extent in the Arctic looks all set to dip below four million square kilometres for only the second time in the satellite record. On the 26th of July it was already the lowest extent on record (72.6% of the LTA) for that date, and much lower (0.387 million km²) than it was at last year on this date. August will tell if the sea ice suddenly collapses as it did in 2012, but that collapse in 2012 was very marked, maybe as my crude estimation suggests the extent will bottom out long before that at around 3.8 million km².
