On February 20, 2024, Antarctica reached its seasonal minimum ice extent, hitting near-historic lows for the third consecutive year. This continues a worrying trend that may indicate a long-term climatic shift, with significant environmental implications.
Antarctic sea ice reached its lowest annual extent on February 20, 2024, with a total of 1.99 million square kilometers . That’s 30 percent below the 1981 to 2010 end-of-summer average—a difference in ice cover that spans an area about the size of Texas. at the University of Colorado, Boulder, track these seasonal and annual fluctuations because sea ice shapes Earth’s polar ecosystems and plays a significant role in global climate.
