The ozone layer is on track to fully recover by 2066, thanks to decades of global action, particularly the 1987 Montreal Protocol.
The agreement to phase out ozone-depleting chemicals has led to a steady reduction in the size of the Antarctic ozone hole.
Satellite data from the World Meteorological Organisation (WMO) shows significant progress, with experts predicting the ozone will return to pre-1980 levels by mid-century.
This recovery is expected to reduce skin cancer rates, protect ecosystems, and contribute to climate change mitigation by lowering greenhouse gas emissions.
Experts caution that illegal chemical production and emerging environmental threats could still pose risks. Thus, continued global vigilance is necessary to ensure full recovery.
With the ozone layer’s healing, scientists hope this success story can inspire solutions to other pressing environmental challenges.
