Sea Ice Extent (Global Antarctic and Arctic) – Day 271 – 2017

Published on by sunshinehours13 Comments

I haven’t called the Antarctic maximum yet because it isn’t unusual for the day of max to be later than 271.

Plus there is a bit of a surge going on.

However, if things don’t change it would be the lowest maximum by about 40,000 sq km. (which occurred in 1986).

PDO AMO Arctic Antarctic

The graphs start from 1950 to show a full 66 year cycle of the PDO and AMO.

I’m graphing anomalies from the mean for all. Sea Ice is in millions of sq km.

PDO versus Arctic Extent  – note that the satellite record for sea ice starts at peak of PDO

Arctic Recovers – 2017 is 8th Lowest Arctic Minimum

Published on by sunshinehours111 Comments

If things hold (and 110,000 sq km of ice would have to melt), day 255 (five days ago) will be the day of Arctic minimum for 2017.

That would still be only the 8th lowest.

If things hold (and they may), day 255 (three days ago) will be the Arctic minimum for 2017.

That would still be only the 8th lowest.

If things hold (and they may not), day 253 (two days ago) will be the Arctic minimum for 2017.

That would still be only the 8th lowest.

7th Lowest Arctic for this day. Higher than 2012, 2016, 2007, 2011, 2015 and 2008.
