Ozone layer recovery is on track, helping avoid global warming by 0.5°C

NAIROBI, 9 January 2023 – The ozone layer is on track to recover within four decades, with the global phaseout of ozone-depleting chemicals already benefitting efforts to mitigate climate change. This is the conclusion of a UN-backed panel of experts, presented today at the American Meteorological Society’s 103rd annual meeting. Examining novel technologies such as geoengineering for the first time, the panel warns of unintended impacts on the ozone layer. Read full article

Earth’s ozone layer on course to mend within decades, UN report finds

Depletion of the ozone  layer has been steadily improving in the wake of the 1989 Montreal Protocol, a global agreement to protect the Earth’s ozone layer by phasing out chemicals such as chlorofluorocarbons (CFCs) initially used as solvents and refrigerants.

The progress is slow, according to the new United Nations report presented on Continue reading Earth’s ozone layer on course to mend within decades, UN report finds
