Overview
- NSIDC reports the Arctic’s winter maximum has reached 14.22 million km² as of March 10, 2026, below last year’s 14.31 million km² peak on March 22.
- If the extent does not expand before the end of March, this season could rank among the five lowest on record and may undercut 2025’s record low.
- The assessment is based on near‑real‑time U.S. satellite observations analyzed by the NSIDC and cited by multiple news outlets.
- Scientists note the Arctic is warming about four times faster than the global average, raising the likelihood of faster summer melt and straining ice‑dependent species such as polar bears and seals.
- Antarctic sea ice likely hit its 2026 minimum at about 2.58 million km² on February 26, a level closer to the long‑term average than in recent years, highlighting a regional contrast.
