In August 2022 the Global Monitoring Laboratory gave the world some good news on the rate of recovery of the ozone layer. The Laboratory analyses annual air samples at remote sites around the globe.
It’s latest report is that the atmospheric concentration of ozone-depleting substances shows the threat to the ozone layer receding below a significant miestone in 2022.
In early 2022, the overall concentration of ozone-depleting substances in the mid-latitude stratosphere had fallen just over 50 percent back to levels observed in 1980, before ozone depletion was significant. This slow but steady progress over the past three decades was achieved by international compliance with controls on production and trade of ozone-depleting substances in the Montreal Protocol on Substances that Deplete the Ozone Layer.
