Any theories about this? NSIDC shows a huge loss of multi-year ice (green) around the pole, Greenland, and the Canadian Archipelago since the end of July. Given that temperatures in those regions have been quite cold since the end of July, I’m having a really tough time understanding what happened.
Much of that region has been below freezing for essentially the entire period.
Satellite data showed essentially no ice loss in that region since the end of July, much less loss of thick multi-year ice. Multiyear ice doesn’t just disappear without open water appearing. There was never any open water in most of the affected areas.
What their maps show is that the ice got younger, not melted. How does ice get younger?
There was never any open water along the coast of Greenland or The Canadian Archipelago this summer. How could the MYI have disappeared? This makes no sense.
