2026 Arctic sea ice maximum ties with record-breaking low set in 2025. This year’s maximum sea ice extent likely occurred on March 15, reaching only 14.29 million km2. This is the smallest maximum in the 48-year satellite record, falling about 20,000 km2 lower than 2025. @nsidc.bsky.social

The margin of error for these satellite records is 30,000 km2, so this year’s 20,000 km2 lower maximum extent is within this margin. The National Snow and Ice Data Center (NSIDC) has declared 2025 and 2026 statistically “tied” for this troubling record-low. Read more: iccinet.org/record-low-2...
