Nothing more than a curiosity for now (and no suggestions otherwise).


A record low maximum is hardly a mere curiosity. See:

At the Royal Society meeting last November it was reported that the September Arctic sea ice minimum was related to the extent of the melt ponds in Spring. Therefore the albedo early in the year controls the ice extent in the autumn. This is a positive feedback process with low albedo early in the season causing even lower albedo later.

We could well see a catastrophic melt this summer.


Here is another chart which shows how dire the situation is:

It has never been this low and recovered. Let's hope I am wrong.
