New thread as presuambly of international significance as the media ,
where mentioning this global minimum, refers to the Wipneus data plots.
I've rechecked my transcriptions and summations from the last 5 records
on the primary source, for the simple global extent

and contrary to the plot on , apparently ceased updating , or my browser
not doing so

I don't have any recent uptick representaion, of recent increasing
global sea-ice extent
I get, in millions of sq km, inexorable depletion of sea-ice
16 Jan 2017, 16.692
17 Jan, 16.593
18 Jan, 16.507
19 Jan, 16.455
20 Jan, 16.444
(would someone else check my figures?)

Anyone know which version is corrct?
I suspect Wipneus is using a different data feed than the Charctic one,
area rather than extent perhaps, JAXA ?


No need to change the luck-would-have-it title, global sea-ice went up
by 1000 sq km for the 21 Jan reading of 16.445
Summarising so far.
Just because experts do not know of a connection between the poles that
could make the global amount of sea-ice so constant for 35 years, does
not mean there is no connection.
Even if it is climate change (insufficient amount of it until last
year), that is now so intrusive that it affects both poles whether in
their summer or winter.


There is a phenomena, known to experts as the polar see-saw, that would explain the "constant" sea ice over the last 35 years:

http://www.sciencedirect.com/science...77379115000554
As the Arctic sea ice decreased the Antarctic sea ice increased. Of course that does not explain why the see-saw has now broken down with both the Arctic and Antarctic sea ice decreasing.
