Lowest Antarctic Sea Ice Record Broken for the Second Year in a Row
Jiping Liu, Zhu Zhu, Dake Chen
Abstract
Antarctic sea ice extent dropped to its lowest level in 45 years of satellite observations on 2023 February 21, the second year in a row with an area below 2 million km 2 . This occurrence raises the question of whether the recent change in Antarctic sea ice is a brief anomaly or an early precursor to a transition to a long-term decline.
