Ozone holes can disappear by 2050

Ozone holes in Antarctica are beginning to shrink in the future and may disappear by 2050 due to chlorofluorocarbons (CFC) emissions reductions and other gases that weaken the ozone layer, according to Japanese scientists. .

This finding is based on studies conducted by Eiji Akiyoshi, a scientist at the National Environmental Research Institute. According to a report published on the institute's website, the ozone layer is currently at its largest, but it is starting to shrink gradually by 2020 and may disappear by 2050.

However, the study also shows that this hole will not fully heal until many years later due to the many refrigerators and air conditioning systems, most of them in the US and Canada, still emitting chemicals made harm to the ozone layer. Both countries are now trying to stop these chemicals with newer products.

Many satellites and ground-based monitoring stations have tracked the hole in the ozone layer in Antarctica since it was discovered in the 1980s. CFC emissions into the earth's atmosphere are decreasing since the mid-1990s. thanks to international emissions reduction efforts.

Earlier this month, US scientists also said that the Earth's ozone layer is slowly recovering from international efforts in the last 20 years.
