And there is more! The hole in the ozone layer may even be fully closed in 43 years, in 2066.
The year begins with positive news. According to the report of the UN Montreal Protocol’s Scientific Assessment Panel, now released, if current policies continue, by 2066 the Antarctic ozone layer will have recovered to 1980 levels, while in the Arctic recovery will be faster, by 2045, and in the rest of the world it could occur by 2040.
In a statement, Meg Seki, executive secretary of the Ozone Secretariat of the United Nations Environment Programme, called the scientists’ findings “fantastic news.”
The scientists concluded that 99% of the banned substances were no longer used, allowing the ozonosphere to recover.
This is the case with chlorofluorocarbons (CFCs), commonly used in products such as air conditioners, refrigerators, and deodorants, but which, once released, damage ozone, allowing more harmful UV-B rays to pass through.
These changes occur due to the Montreal global protocol, signed in 1987, to safeguard the layer that protects planet Earth from ultraviolet rays.
According to the UN, the recovery of the ozone layer will prevent a 0.5ºC increase in the planet’s global temperature.
