A new record minimum for Antarctic sea ice

Nature Reviews Earth & Environment volume 3, pages 215–216 (2022)Cite this article

Subjects

Antarctic sea ice extent reached a new record low of 1.965 million km2 on 23 February 2022. This extent is approximately 32% below climatological values and might indicate a transition to new, more extreme, annual fluctuations.
