Arctic Sea Ice Extent: October 31, 2024

October 31, 2024: The Arctic sea ice has continued to increase this week but at a lesser rate of 5.75% (as opposed to last week’s rather large increase rate of 20.19%), from the level on 10/24/2024 of 7.109 M km2 to 7.543 M km2 for this week.

The negative sea ice anomaly this week was greater than the anomaly of -1.169 M km2 on 10/24/2024 to a higher negative anomaly of -1.395 M km2 on 10/31/2024, and so more anomalously negative for this time of year than last week.
