Central Arctic Freezing Up Rapidly

The blink comparator shows changes in the ice near the North Pole at 87.5N 168.0E over the last four days. As you can see, all of the open water has frozen over. This causes area measurements to increase.

We are also seeing increases in extent around the periphery of the ice pack. The modified NSIDC image shows the increase in ice (green) over the last three days.
