Arctic Sea Ice Extent: September 5, 2024

September 5, 2024:  The Arctic sea ice has continued to decrease this week but at a slightly greater rate of 4.78% (as opposed to last week’s decrease rate of 4.75%), from the level on 08/29/2024 of 4.577 M km2 to 4.358 M km2 for this week.  For this time of year, we are now essentially still tied for the second lowest amount in the record with the level from 2020.

The negative sea ice anomaly this week was less than the anomaly of -1.173 M km2 on 08/28/2024 to a lower negative anomaly of -1.155 M km2 on 09/05/2024, and so a bit less anomalously negative for this time of year.
