Arctic Sea Ice Extent: September 11, 2024

September 11, 2024:  The Arctic sea ice has continued to decrease this week but at a lesser rate of 1.72% (as opposed to last week’s decrease rate of 4.78%), from the level on 09/05/2024 of 4.358 M km2 to 4.283 M km2 for this week.  For this time of year, we are now essentially tied for the third lowest amount in the record with the level from 2023.  We could be pretty close to the seasonal turnaround to the ice growth season now.

The negative sea ice anomaly this week was lower than the anomaly of -1.155 M km2 on 09/05/2024 to a lesser negative anomaly of -1.135 M km2 on 09/11/2024, and so a bit less anomalously negative for this time of year.
