Biggest Ozone Layer Hole above Arctic naturally closes

Whether half of the world is on lockdown or not, the Earth has its own ways of healing itself after different kinds of destructions brought by its residents or natural phenomena

Earlier this month, scientists discovered a rare hole in the ozone layer that runs over 1million square kilometers in area, making it the largest ozone layer hole. The hole was located above Arctic and was understood to have resulted from the low temperatures at the north pole. It is believed to have posed a big threat to humans if the hole had managed to move south with the air to populated areas.

Fortunately, the earth has already healed itself and closed the largest hole. Copernicus' Atmosphere Monitoring Service (CAMS) and Copernicus Climate Change Service (C3S) confirmed this through a tweet on April 23. Note that the healing of the ozone layer hole is because of the polar vortex – high altitude currents bringing cold air into the polar regions, and not because of the reduced pollution brought by the coronavirus lockdown.

It is yet to be confirmed if the phenomenon is related to climate change as well as its consequences.
