The ozone layer has been on the mend thanks to global action, including a major international treaty to phase out ozone-damaging chemicals. But that doesn’t mean it’s fully healed.

On current trends, the ozone layer is on track to recover to 1980 levels by around 2066 over the Antarctic, 2045 over the Arctic and 2040 for the rest of the world, the United Nations agency said.

A U.N. report presented Monday in Denver shows the ozone layer on track to fully recover by 2066, but scientist David W. Fahey said we need to remain vigilant.

They expect the ozone over the Arctic to be healed by 2045, with the Antarctic lagging behind just a few decades to 2066. The ozone layer above the Antarctic is expected to heal completely by 2066.
