The United Nations report: Ozone layer recovery on track.
A new report from the U.N., which includes key scientific contributions from National Oceanic and Atmospheric Administration and international partners, confirms that the recovery of Earth’s protective ozone layer is on track, and that the Montreal Protocol, the international treaty that guides the phase-out of ozone-destroying chemicals, has had the additional benefit of slowing global warming.
Approximately 230 scientists from 30 countries contributed to the 2022 Ozone Assessment, which is led by the World Meteorological Organization, United Nations Environment Programme, NOAA, NASA and the European Commission.
“The Montreal Protocol is one of the most important and successful global environmental treaties ever,” said David Fahey, director of NOAA’s Chemical Sciences Laboratory and Co-chair of the Scientific Assessment Panel of the Montreal Protocol. “Since the adoption of the Montreal Protocol, NOAA has led the development of the report, which is produced every four years to guide and support the decisions of the Montreal Protocol. NOAA’s leadership aligns with its substantial and longstanding commitment to stratospheric ozone research with models, observations and laboratory studies.”
By banning new production and use of CFCs, the Montreal Protocol eliminated a significant contributor to climate change, avoiding a potential additional global temperature increase of 0.5 to 1 degree Fahrenheit by 2100.
