Antarctic sea ice extent has fallen recently, and was 16.73 million km² on October 1, 2026, a record low for the time of year. It can be expected to keep falling strongly over the next few months, due to the change in seasons and as El Niño gains in strength. arctic-news.blogspot.com/2026/09/will...
