Largest-ever Ozone hole finally closes

Apr 27, 2020 10:33 IST

It's confirmed! The largest hole in the ozone layer, located above the Arctic, has finally closed according to Copernicus' Atmospheric Monitoring Service and Copernicus Climate Change Service. The healing of the 1 million square km wide hole has been attributed to the polar vortex and not reduced levels of pollution due to the covid-19 lockdown. The polar vortex enabled ozone-rich cold air to flow into the arctic, leading to its closure.The ozone layer protects the Earth from the harmful ultra-violet rays of the sun and if the the hole moved towards the south, it would have posed a greater threat.
