Arctic sea ice minimum on Sept 12, 2026 was 4.60 million km2 — tied with 2008, 2010, and 2025 for tenth-lowest. The last 20 years are now the 20 lowest extents on record.
Barrier-breaking signals
56 of 415 eventsEvery real-world crossing the tracker has logged across nine scaffolds. Each entry names the moment, cites the source, and shows which forks it tilts. Pressure moments are the ones where the floor moved faster than any forecast window said it would.
Direction per event — which pole each crossing pulls toward — is scheduled for the next enrichment cycle. For now, chips show which forks the event touches without claiming a side.

How to read this feed
Scaffold tag names the domain the event sits inside. Fork chips name which open fork(s) this crossing tilts — the specific timeline questions this moment contributes evidence to. Confirmed events are published and sourced; reported claims are announced but not yet independently verified; leading indicators are directional signals, not canonical crossings. A pressure moment flag means the pace exceeded what any forecast window had scheduled.
