Is the hole in the ozone layer closing 2020?

“The unprecedented 2020 Northern Hemisphere ozone hole has come to an end,” CAMS researchers tweeted on April 23. … Meanwhile, the annual Antarctic ozone hole, which has existed for roughly four decades, will remain a seasonal reality for the foreseeable future.

What destroys the ozone layer?

Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere.

Does lightning repair the ozone layer?

The ozone layer is healing — but it could take another 50 years to completely recover. According to a 2018 study, portions of the ozone layer have recovered at a rate of 1% to 3% per decade since 2000. At this rate, Northern Hemisphere and mid-latitude ozone are likely to recover completely in the next 10 years.

The annual Antarctic ozone hole – the 12th-largest on record – reached its peak size for 2020 on September 20, at about 9.6 million square miles (24.8 million square km), roughly three times the area of the continental United States, Observations revealed the nearly complete elimination of ozone in a 4-mile-high (6-km- …

Is there still a hole in the ozone layer over Australia?

The ozone layer is depleted in two ways. Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. Data collected in the upper atmosphere have shown that there has been a general thinning of the ozone layer over most of the globe.
