​If trends continue, the ozone layer should recover by 2066

According to a UN research, the ozone layer might be fully repaired by 2066 if we continue lowering ozone-depleting compounds.

Under the 1987 Montreal Protocol, 100 chemicals were designated as harmful to the ozone layer, including CFCs found in aerosols.

The Scientific Assessment Panel to the Montreal Protocol on Ozone Depleting Substances reports on progress every four years.

The newest report on rebuilding the ozone layer will be delivered at the 103rd annual meeting of the American Meteorological Society.

According to the findings, most of the planet should recover by 2040, the Arctic by 2045, and the Antarctic by 2066.

The report also noted efforts in reducing hydrofluorocarbons (HFCs), which are less detrimental to ozone than CFCs but still bad for the environment.

These HFCs do not directly erode the ozone layer, but they contribute to global warming. The Montreal Protocol was revised to target the decrease of these HFCs, which have had increasingly fewer usages over the years.

If we continue on our current path, we could prevent 0.3 to 0.5 degrees Celsius by 2100.

"The newest quadrennial report shows ozone recovery is on pace. The Montreal Protocol has helped mitigate climate change "Meg Seki, UN Environment Program Ozone Secretariat Executive Secretary.

"The Protocol has been an environmental champion for 35 years."

Professor Petteri Taalas, Secretary-General of the Globe Meteorological Organization, said these encouraging accomplishments should motivate the rest of the world to work toward positive environmental consequences.

"Climate action follows ozone action. Our accomplishment phasing out ozone-eating chemicals indicates what can and must be done to transition away from fossil fuels, reduce greenhouse gases, and limit temperature increase "saying
