Mysterious CFC emissions damage ozone layer and climate

Scientists and environmental groups warn about an underestimated threat to the global climate and the ozone layer. Emissions of various chlorofluorocarbons (CFCs) from unknown sources have been discovered worldwide, reported the latest Scientific Assessment of Ozone Depletion 2022, published by the World Meteorological Organization WMO and the UN Environment Programme UNEP, among others. The substances damage the protective layer and in some cases heat the atmosphere considerably more than carbon dioxide.
