Ozone layer may recover in decades

The Ozone layer, which began depleting in the 1970s could recover within a few decades, scientists said in a U.N.backed report, see: https://ozone.unep.org/system/files/documents/Scientific-Assessment-of-Ozone-Depletion-2022-Executive-Summary.pdf. Ozone levels between the polar regions are expected to reach pre-1980 levels during the 2040s, if current policies continue, and ozone holes should also recover.

An international agreement in 1987 to stop using the harmful chemicals that were damaging the layer has been successful, the major assessment says.

The ozone layer is a thin part of the Earth’s atmosphere that absorbs most of the ultraviolet radiation from the Sun.
