December 19, 2024: (After a short lag in data uploads at NSIDC we have caught up. This report will be for 8 days from Dec 11th); the Arctic sea ice has continued to increase this week at a greater rate of 5.77% (as opposed to last week’s increase rate of 2.62%), from the level on 12/11/2024 of 11.002 M km² to 11.676 M km² for this week. 

The negative sea ice anomaly this week was lower than the anomaly of -1.0478 M km² on 12/11/2024 to a lesser negative anomaly of -0.9345 M km² on 12/19/2024, and so less anomalously negative for this time of year than last week.
