It’s not quite reached the minimum sea ice extent in the Arctic but it’s close. The average date for the Arctic minimum is in fact the 11th of September as far as I can see, and looking at the latest figures up until the 7th of September that’s still in doubt, especially as the minima could still occur as late as the 21st (as it did in 1989) which could mean a further two weeks of decline.
Meanwhile 180° south, the Antarctic sea ice is reaching its peak, which if my programming is correct is still 12 days short of the average data maxima occurs on the 19th of September. The increase in sea ice has taken quite a knock in the last 10 days, and at the moment the 2016 maximum has dropped to the 22nd highest since 1979.
Looking at the bigger picture and the rolling 365 day mean since 1989 it’s clear that as the Arctic sea ice has dropped by 14.1% in those 27 years whilst at the same time the Antarctic sea ice has increased by 7.6%, although in the last year that increase has slowed quickly.
