Lowest Antarctic Sea Ice Record Broken for the Second Year in a Row
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 km2. 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.
