The hole in the ozone layer this year is bigger than the area of ​​Antarctica

This is certainly a matter of great concern when the ozone hole this time is estimated to be larger than the whole of Antarctica.

According to the European Union's Copernicus Atmospheric Monitoring Service, the hole in the ozone layer that forms annually over Antarctica is now larger than the whole of Antarctica. Even if climate change were to stop completely, there is still a very small chance the ozone layer could recover until the 2060s or 2070s, the scientists said.

The ozone layer is located between 14 and 35km above Earth and it is important for protecting the planet from ultraviolet radiation. The ozone layer typically depletes and forms a hole in the Atlantic Ocean each spring, and this process lasts from August to October in the Southern Hemisphere.

This vulnerability is caused by chemicals such as chlorine, carbon and bromine (chlorofluorocarbons) moving into the stratosphere and creating catalytic reactions as winter approaches. It is also connected to the Antarctic vortex. This is a large area and has swirls of air circulating in the upper atmosphere, while also moving around the Earth.

As stratospheric temperatures begin to rise in late spring, ozone depletion typically slows and returns to normal levels by December.

The director of the Copernicus Atmospheric Administration Vincent-Henri Peuch said: "This year, the ozone hole has grown as expected at the start of the season. It looks pretty much the same as last year and isn't really special for us. through early September. But then it turned into one of the largest and longest-lived ozone holes on record in our data by the end of this season.Now our projections show the hole. This year's hole has grown into a larger-than-normal hole.The eddy is fairly steady and the temperature in the stratosphere is even lower than last year, so it could continue to rise slightly over the next two or three weeks. ".

Although experts believe that the reduction and elimination of ozone-depleting chemicals under the Montreal Protocol since 1987 have prevented catastrophic consequences, the size of the hole in the ozone This year is extremely worrying.

It also makes scientists wonder if we are doing enough to prevent further deterioration of the planet. Stronger and more sustainable collective action is certainly needed to mitigate climate change and help the ozone layer recover soon.
