May 1, 2025: With 8 days worth of data this time we are returning to the usual schedule; the Arctic sea ice has experienced a larger decrease for this week of 3.53% (last week’s decrease rate was 0.39%), from the level on 04/23/2025 of 13.900 M km² to 13.409 M km² for this week.

The negative sea ice anomaly this week was higher than the anomaly of -0.1564 M km² on 04/23/2025 to a greater negative anomaly of -0.2665 M km² on 05/01/2025, and so more anomalously negative for this time of year.
