UN predicts ozone layer recovery by mid-century

The UN reports the ozone layer is healing and expected to fully recover by mid-century due to international cooperation. The ozone hole over Antarctica was smaller in 2024, a positive sign for global health. This recovery demonstrates the effectiveness of scientific warnings and collective action. The Montreal Protocol, signed in 1987, phased out ozone-depleting chemicals, leading to this projected restoration by around 2066 for Antarctica.
