WMO says ozone layer is healing fast and could hit 1980s levels by mid century

This recovery is linked to phasing out ozone killers

A new WMO report says the Earth’s ozone layer is on a clear recovery path, projected to return to 1980s levels by mid-century. The shift is attributed to the Montreal Protocol, which curbed ozone-depleting substances. Early signs show up in a smaller 2024 Antarctic ozone hole, but scientists warn that long-term monitoring is still essential for full healing.
