The ozone layer works as a protective shield as it prevents Sun's ultraviolet rays- which can cause skin cancer- from entering Earth.
Confirming the much-welcomed development, a spokesperson for CAMS wrote on Twitter: "The unprecedented 2020 northern hemisphere #OzoneHole has come to an end".
Thus, despite what you may be thinking, it's recovery most likely can't be tracked to the reduction in pollution due to the coronavirus pandemic.
This ozone hole became the largest one ever recorded in the Arctic region spanning an area of over 620,000 square miles (or 997793.28 kms).
However, fortunately, there has been some good news from there too: previous year, the ozone hole above the Antarctic was observed to be at its smallest since it was first discovered. "The #PolarVortex split, allowing #ozone-rich air into the Arctic, closely matching last week's forecast from the #CopernicusAtmosphere Monitoring Service". For most of us being stuck at home during Covid-19, any form of positive news, especially those relating to mother nature and the well-being of our planet is indeed a welcoming sight. It is found in Earth's stratosphere, a layer of the atmosphere around 10-50 kilometres above sea level. In recent days the vertex has broken and weakened letting warm air inside.
Unlike the hole that developed over the Arctic, the Antarctic ozone hole in the Southern Hemisphere is typically caused by chemicals such as chlorine and bromine migrating into the stratosphere. While ozone layer depletion also occurs in the Arctic, it is not as severe as observed in the Antarctic.
The article also quoted a member of the German Aerospace Center, Diego Loyola, as saying, "The ozone hole we observe over the Arctic this year has a maximum extension of less than 1 million sq km".
The scientist further goes on to add that since March 14, the ozone columns have depleted over the Arctic "to what is normally considered 'ozone hole levels, ' which are less than 220 Dobson Units".
