January 19, 2023: Over the past week, the sea ice has continued to increase and at a slightly lower rate than last week, of 2.32%, from the level on 01/12/2023 of 13.229 M km² to 13.543 M km² for this week. 

The negative sea ice anomaly this week was slightly less than the anomaly of -1.010 M km² on 01/12/2023 to a lower negative anomaly of -0.953 M km² on 01/19/2023 and so a bit less anomalously negative for this time of year.
