A 1 million square kilometre wide hole over the Arctic has now closed. The hole was understood to be a result of low temperatures at the north pole.
According to reports, scientists have confirmed that the 1 million square kilometre wide hole over the Arctic has now closed. A rare hole in the ozone layer, spreading over 1 million square kilometre in area, was discovered by scientists earlier this month. The hole was understood to be a result of low temperatures at the north pole.
Copernicus' Atmosphere Monitoring Service (CAMS) and Copernicus Climate Change Service (C3S), implemented on behalf of the European Commission, have now confirmed that the hole over the north pole has healed itself.
A recent tweet by the agency also explains the reasons behind the same. Note that the healing of the hole in the Earth’s ozone layer has nothing to do with the ongoing reduction in pollution due to COVID-19 lockdown. Instead, it is because of the polar vortex - high-altitude currents bringing cold air to the polar regions.
