## Video thesis
Cleo Abram uses Antarctica, the 1985 ozone-hole discovery, the Antarctic Treaty and the Montreal Protocol as an optimistic science-policy story: the current path is not the only possible future path.

## Verification summary
The source trail supports the core ozone-history and Montreal Protocol claims. The strongest official anchors are UNEP/WMO for recovery projections and phase-out scale, NOAA/NASA for the latest 2025 ozone-hole measurements, British Antarctic Survey for the 1985 discovery history, and the Antarctic Treaty Secretariat for the peace/science governance framework.

The article does not treat the ozone story as “solved forever.” It keeps the main caveats: the Antarctic ozone hole still forms seasonally, recovery depends on policies staying in place, weather/polar-vortex conditions affect year-to-year hole size, and Antarctic sea ice is a separate but related climate-evidence track.
