Ozone recovery brings progress, with a long way still to go
The WMO’s new bulletin says the Antarctic ozone hole in 2025 was among the smallest recorded in recent decades.
The organisation links the longer recovery trend to international limits on ozone-depleting chemicals, while stressing that weather also drives annual variation. A smaller hole in one year does not mean the ozone layer has fully recovered.
