JAXA ARCTIC SEA ICE EXTENT: 12,178,953 KM2 as at 03-Jan-2021 - Extent gain on this day 48k, 3 k less than the average gain on this day (of the last 10 years) of 51k, - Extent gain from minimum on this date is 8,624 k, which is 489 k, 6% more than the 10 year average of 8,135 k. - Extent is at position #2 in the satellite record
Global-mean air temperature can hence be interpreted as the most important control variable on future Arctic sea-ice evolution. * "The observed linear relationship between Arctic sea ice coverage and global-mean air temperature suggests Arctic sea-ice coverage to drop below 1 million km2 in more than 50% of all years for a global warming of ...
On September 11, Arctic sea ice likely reached its annual minimum extent of 4.28 million square kilometers (1.65 million square miles). The 2024 minimum is the seventh lowest in the nearly 46-year satellite record. The last 18 years, from 2007 to 2024, are the lowest 18 sea ice extents in the satellite record…

The cyclone resulted in a record (over the period 1979–2022) weekly loss of regional sea ice area and surface wind speeds, and generated ocean waves exceeding 8 m that impinged on sea ice in the Barents sea, observed via satellite altimetry as large waves-in-sea ice up to 2 m in amplitude more than 100 km into the ice pack.

It seems that the meme du jour on social media consists of posting a recent graph of DMI Arctic sea ice extent accompanied by the following claim:: How about looking into the fact that the arctic sea ice extent has grown by 1 million km² compared to this time last year despite a "warming world". Wasn't it supposed to be ice free in the summers?
NSIDC ARCTIC SEA ICE AREA (5-day trailing average): 11,740,477 KM2 as at 11-Jan-2023 - Area gain on this day 49k, which is 14 k more than the average gain on this day (of the last 10 years) of 35k, - Area gain from minimum on this date is 8,523 k, which is 67 k, 0.8% less than the 10 year average of 8,590 k.
NSIDC ARCTIC SEA ICE AREA (5-day trailing average): 4,758,102 KM2 as at 23-Oct-2024 - Area gain on this day 106k, which is 0 k less than the average gain on this day (of the last 10 years) of 106k, - Area gain from minimum on this date is 2,246 k, which is 109 k, 4.6% less than the 10 year average of 2,355 k.
