UN: Ozone layer is on track to recover in the next 40 years

“The Earth’s ozone layer is on its way to recovering within the next 40 years, thanks to decades of work to get rid of ozone-damaging chemicals, a panel of international experts backed by the United Nations has found. The ozone layer serves an important function for living things on Earth. This shield in the stratosphere protects humans and the environment from harmful levels of the sun’s ultraviolet radiation. … experts discovered a hole in the ozone layer in May 1985. Scientists had previously discovered that chemicals such as chlorofluorocarbons, used in manufacturing aerosol sprays and used as solvents and refrigerants, could destroy ozone. Two years after the discovery of the dire state of the ozone layer, international bodies adopted a global agreement called the Montreal Protocol. This established the phaseout of almost 100 synthetic chemicals that were tied to the destruction of the all-important ozone.” (01/10/23)
