The 2020 hole reached a size of about 9.6 million square miles (25 million square kilometers) in early October. ESA said this size was comparable with the holes that formed in 2015 and 2018.

An image released with the statement shows the hole extending across most of Antarctica and a video lets you track the changes from late September through the middle of October…Read more>>
