If current policies remain in place, the ozone layer is expected to recover to 1980 levels by around 2066 over the Antarctic, by 2045 over the Arctic and by 2040 for the rest of the world.

A 2016 update to the so-called Montreal Protocol also phased out hydrofluorocarbons , which do not directly deplete ozone but have a strong climate change effect.Since the chemicals were banned, there has since been a “notable recovery” in the upper layer of the stratosphere, according to the report by the Scientific Assessment Panel to the Montreal Protocol, which is updated every four years.
If current policies remain in place, the ozone layer is expected to recover to 1980 levels — before the appearance of the hole — by around 2066 over the Antarctic, by 2045 over the Arctic and by 2040 for the rest of the world. The hole, which is over the Antarctic, has been shrinking in area and depth since the year 2000, the report said.

UN says ozone layer slowly healing, hole to mend by 2066DENVER (AP) — Earth’s protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says. A once-every-four-years scientific assessment found recovery in progress, more than 35 years after every nation in the world agreed to stop producing chemicals that chomp on the layer of ozone in Earth’s atmosphere that shields the planet from harmful radiation linked to skin cancer, cataracts and crop damage.
