You can see it on the interactive tool here: https://nsidc.org/sea-ice-today/sea-ice-tools/charctic-inter...

You can click on individual years, but the decade average plots are the most revealing. You can see the average has dropped significantly each decade, and the drop is actually larger in the warmer months (~35%) than in the colder months (~10%) for the year range 1980 to 2020.

Just checked the link. While average is decreasing for the artic sea, average is slightly increasing in the Antarctic. Which makes me think, since most of the ice is on actual land and not on the ocean. Is there another tool that tracks ice on land?
