The ozone hole that plays a big role in global warming over Antarctica is shrinking, researchers say it will eliminate the problem of climate change

Recently, scientists revealed that the “shrinking” ozone layer gives the world new hope on climate change. The report says the layer above the Antarctic ozone hole has grown to around 23.2 million square kilometres.

Previously, a report showed that the hole in the ozone layer was about 24.8 million square kilometers, and given the current estimate, it shows a slight shrinking of the hole in the ozone layer.

The research examined the current trend using tools such as the Aura, Suomi NPP and NOAA-20 satellites. As NASA and NOAA researchers watched, they found the one-day maximum hole was 26.4 million square kilometers, which was larger than last year.

A Dobson spectrophotometer, an optical instrument that records ozone between the surface and peripheral space, was also used by the researchers.

Current data shows a good sign as the hole in the ozone layer has become significantly smaller compared to measurements in the early 1990s and early 2000s.

The Montreal Protocol’s ban on the release of dangerous ozone-depleting chemicals known as chlorofluorocarbons, or CFCs, caused damage to the hole, which has been recovering ever since.

NASA said: “In summary, negative changes in the ozone layer are offset by positive changes in human behavior, allowing the ozone layer to rebuild.” “The role that the ozone hole itself plays in global warming and resulting climate change is small compared to the impacts from human activities.”
