Arctic Sea Ice Extent
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.

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.

For this time of year, we are now essentially tied for second lowest amount in the record with the level from 2020. The negative sea ice anomaly this week was less than the anomaly of -1.272 M km2 on 08/22/2024 to a lower negative anomaly of -1.173 M km2 on 08/29/2024, and so a bit less anomalously negative for this time of year.
Arctic Sea Ice Extent: August 22, 2024
August 22, 2024: The Arctic sea ice has continued to decrease this week but at a greater rate of 8.49% (as opposed to last week’s decrease rate of 5.23%), from the level on 08/15/2024 of 5.251 M km2 to 4.805 M km2 for this week. For this time of year, we are now essentially still tied at the 3rd lowest amount in the record with the level from 2020. The negative sea ice anomaly this week was greater than the anomaly of -1.212 M km2 on 08/15/2024 to a slightly higher negative anomaly of -1.272 M km2 on 08/22/2024, and so a bit more anomalously negative for this time of year.
Arctic Sea Ice Extent: August 15, 2024
August 15, 2024: The Arctic sea ice has continued to decrease this week but at a lesser rate of 5.23% (as opposed to last week’s decrease rate of 11.22%), from the level on 08/08/2024 of 5.541 M km2 to 5.251 M km2 for this week. For this time of year, we are now essentially tied at the 3rd lowest amount in the record with the level from 2020. The negative sea ice anomaly this week was lower than the anomaly of -1.355 M km2 on 08/08/2024 to a lower negative anomaly of -1.212 M km2 on 08/15/2024, and so less anomalously negative for this time of year.
Arctic Sea Ice Extent: August 8, 2024
August 8, 2024: The Arctic sea ice has continued to decrease this week and at a greater rate of 11.22% (as opposed to last week’s decrease rate of 8.37%), from the level on 08/01/2024 of 6.241 M km2 to 5.541 M km2 for this week. For this time of year, we are now essentially tied at the 2nd lowest amount in the record in 2012 and just above the lowest amount for this time in 2020. Three out of the last four weeks have had double digit percentage losses in sea ice. The negative sea ice anomaly this week was higher than the anomaly of -1.142 M km2 on 08/01/2024 to a greater negative anomaly of -1.355 M km2 on 08/08/2024, and so more anomalously negative for this time of year.
