The floating cap of sea ice on the Arctic Ocean shrank this summer to what is probably its smallest size in at least a century of record keeping, continuing a trend toward less summer ice, a team of climate experts reported yesterday.

Both polar caps shrink and regrow following the temperature fluctuation of the Martian seasons; there are also longer-term trends that are not fully understood.

However, whereas the northern cap is shrinking at a rate of about 3% per decade, the southern cap is expanding at a rate of 0.8% per decade.

In additon to tracking the storms, it is also interesting to watch how the seasonal cap shrinks from the beginning to the end of the animation.
