The negative sea ice anomaly this week was higher than the anomaly of -0.692 M km2 on 04/13/2023 to a lesser negative anomaly of -0.477 M km2 on 04/20/2023 and so less anomalously negative for this time of year.

The negative sea ice anomaly this week was higher than the anomaly of -0.940 M km2 on 04/06/2023 to a lesser negative anomaly of -0.692 M km2 on 04/13/2023 and so less anomalously negative for this time of year.

April 7 2023:  Over the past week, the sea ice has continued to decrease, and since last week, by a rate at 1.62%, from the level on 03/31/2023 of 14.284 M km2 to 14.053 M km2 for this week. The negative sea ice anomaly this week was lower than the anomaly of -0.885 M km2 on 03/31/2023 to a grater negative anomaly of -0.940

March 30 2023:  Over the past week, the sea ice extent rose one more time on March 24th to 14.477 M km2, and then has been on a steady decline since then with a net decrease, since last week, by a relatively small rate at 0.82%, from the level on 03/23/2023 of 14.402 M km2 to 14.284 M km2 for this week; and so we

March 23 2023:  Over the past week, the sea ice has been going through some ups and downs and has now shown a net increase, since last week, by a very small rate at 0.31%, from the level on 03/16/2023 of 14.357 M km2 to 14.402 M km2 for this week; and so while I think we are in the sea ice

March 16 2023:  The sea ice has decreased since last week, by a bit higher rate at 1.46%, from the level on 03/09/2023 of 14.569 M km2 to 14.357 M km2 for this week; and so it looks like we are now definitely in the sea ice decline season. The negative sea ice anomaly this week was lower than the anomaly of

March 9 2023: The sea ice has decreased since last week at a very small level of 0.40%, from the level on 03/02/2023 of 14.628 M km2 to 14.569 M km2 for this week. While that is not a large decrease, it really is the tipping point for the sea ice season. The week actually started with an initial small increase on March 7th,

March 2 2023: Over the past week, the sea ice has continued to increase and at slightly higher rate than last week, of 1.72%, from the level on 02/23/2023 of 14.376 M km2 to 14.628 M km2 for this week; and so while growing at a bit higher rate this week, we are still quickly approaching the end of the sea ice growth

February 23, 2023: Over the past week, the sea ice has continued to increase and at only a very slightly higher rate than last week, of 0.41% (yes 0.41%), from the level on 02/16/2023 of 14.317 M km2 to 14.376 M km2 for this week; so coupled with the progressively slowing down of sea ice growth over the last several weeks, it is possible that
