Antarctic sea ice minimum extent, March 1 2025

On March 1, 2025, Antarctic sea ice officially reached its minimum extent for the year.

This cycle of growth and melting occurs every year, with the ice reaching its smallest size during the southern hemisphere's summer.

This year's melt season concluded with a sea ice area of 764,000 square miles (1.98 million square kilometers) compared to the average minimum observed during the satellite era (1981-2010).

That is slightly larger than the state of Texas.

According to the National Snow and Ice Data Center, this ties with 2022 and 2024 as the second-lowest sea ice extent recorded by satellites, reflecting a trend of declining coverage over time.

The extent of sea ice is critical for polar ecosystems and has far-reaching implications for Earth's climate and weather patterns.
