November 21, 2024: The Arctic sea ice has continued to increase this week but at a lower rate of 5.34% (as opposed to last week’s increase rate of 6.95%), from the level on 11/14/2024 of 9.068 M km² to 9.580 M km² for this week.

The negative sea ice anomaly this week was essentially equal to the anomaly of -1.0078 M km² on 11/14/2024 at a ever so slightly more negative anomaly of -1.0080 M km² on 11/21/2024, and so very slightly more anomalously negative for this time of year than last week.
