Ozone Layer Protection
But through domestic and international action to phaseout these substances, the ozone layer is healing and should fully recover by about 2065.
Countries phased out chlorofluorocarbons and similar chemicals under the Montreal Protocol after scientists linked them to the Antarctic ozone hole. The UN-backed scientific assessment now projects the layer healing to 1980 benchmark levels around 2065 over Antarctica — evidence that a planetary atmospheric problem can actually be reversed when every nation acts together.
Thanks to a global phase-out of ozone-destroying chemicals, the ozone layer should fully heal by about 2065.
