December 29, 2022: Over the past week, the sea ice has continued to increase but at an extremely lower rate from last week, of 0.31%, from the level on 12/22/2022 of 12.558 M km² to 12.597 M km² for this week.

The negative sea ice anomaly this week was greater than the anomaly of -0.633 M km² on 12/22/2022 to a more negative anomaly of -1.001 M km² on 12/29/2022 and so more anomalously negative for this time of year.
