Arctic Sea Ice Extent: January 18, 2024

January 18, 2024:  The sea ice has continued to increase, but at a much lesser rate of 0.81% (from last week’s growth rate of 3.38%), from the level on 01/11/2024 of 13.920 M km2 to 14.034 M km2 for this week.

The negative sea ice anomaly this week was less than the anomaly of -0.096 M km2 on 01/04/2024 to a smaller negative anomaly of -0.046 M km2 on 01/18/2024, and so less anomalously negative for this time of year.
