A UN-backed group of experts has stated at the 103rd annual meeting of the American Meteorological Society that the ozone layer is on the road to recovery (WMO, 2022). Furthermore, it states that if the current pace is maintained, the values ​​that were lost with the appearance of the hole in the layer could be recovered around 2066 in Antarctica, in 2045 in the Arctic and around 2040 in the rest of the world. The report of the Scientific Assessment Group of the Montreal Protocol confirms that “the progressive elimination of almost all prohibited substances that damaged it managed to protect this protective shield of the planet, which allowed a notable recovery in the upper stratosphere and a decrease in the human exposure to the sun's harmful ultraviolet rays.

The impact that the Montreal Protocol has Antigua and Barbuda Email List had on climate change mitigation cannot be overemphasized. "In the last 35 years, it has become a true defender of the environment," said the executive secretary of the Ozone Secretariat of the United Nations Environment Programme. Amendments such as the Kigali agreement reached in 2016 that requires the progressive reduction of the production and use of some hydrofluorocarbons, have contributed to the mitigation of climate change.



The perspectives of the amendment for 2100 will prevent global warming between 0.3 and 0.5 °C, as the report points out. The evaluation of the report has been based on extensive studies, research and data collected from the World Meteorological Organization (WMO), the United Nations Environment Program (UNEP), the National Office of Oceanic and Atmospheric Administration (NOAA), the National Aeronautics and Space Administration (NASA) and the European Commission.
