Summary

Story summary

In 2026, Antarctic sea ice reached a near-average summer minimum of 996,000 square miles, as shifting southern winds pushed ice outward.
However, it remains about 100,000 square miles below the 1981-2010 average, signaling this relief is not a full recovery.
Rising surface salinity and warmer deep water threaten ice preservation.
Future summers will determine whether this rebound is temporary or a new trend.
