Earth At Last Fixed The Biggest Ozone Layer Hole Above Arctic, Recovering 1 Million Square Km

A new exemplary activity of such has been identified since the scientists assure that a hole with a width of 1 million kilometres above the Arctic has now shut.

rare hole in the ozone layer, spreading beyond 1 million square kilometres in the region, was found by scientists before this month. The hole was identified to be an impact of low temperatures at the north pole. If this blockbusting hole hadn’t moved south with the air currents, it would be a direct threat to mankind.

Copernicus Climate Change Service (C3S) which was implemented on behalf of the European Commission along with Copernicus’ Atmosphere Monitoring Service (CAMS) has stated that the hole above the north pole has recovered by now. And also a tweet that was posted by the agency recently explains the causes behind the same.

Accordingly, the recovery of the hole in the ozone layer of the Earth has no connection with the reduction of pollution due to the current quarantine lockdown. They point out the reasons as the polar vortex – high-altitude currents that bring cold air to the polar regions.

Copernicus ECMWF states that this year’s polar vortex was highly powerful along with very cold temperatures in it. This has affected the creation of stratospheric clouds that harm the ozone layer due to their reaction with the CFC gases. It’s noted that the usage of CFC gases by humans was totally prohibited by the Montreal Protocol in 1987.

At present, the hole of the ozone layer has become normal due to the weakening of the polar vortex. According to the predictions of the Copernicus ECMWF, it will form again without affecting the ozone layer in the same manner next time.


It’s said that these types of holes in the ozone layer are usually generated above the South and Antarctic Pole, mostly during the austral spring, July to September as the coldness of the stratosphere is naturally high around that time.

The reason for the hole in the ozone layer above the Arctic at present is the consistent and strong polar vortex and it results in more collection of ozone-depleting chemicals than normalcy level. It’s argumental if this significant change in the ozone layer has any relation to the climate changes on Earth.
