The Most Massive Arctic Ozone Layer Hole Healed Itself Up

Something peculiar emerged over the Arctic this year. A hole appeared in the ozone layer and got quite the features. The European Commission’s Copernicus (the CAMS) satellite survey spotted the odd happening, and now has proof that the hole closed itself up.

The ozone layer shields the Earth, similar to a sunscreen, protecting life from threatening ultraviolet radiation. The most known ozone hole is the one that appears annually in the Antarctic. What’s different this time? Also, how significant is this Arctic ozone hole? Scientists gathered around and drew some conclusions.

The Arctic Ozone Layer Hole Peculiarities

Arctic ozone holes aren’t that strange at all. There was an event back in 2011, similar to the current one, but a little bit smaller. The CAMS determined this year’s northern hemisphere ozone hole as record-breaking and odd. But what’s more awkward is what the European Center for Medium-Range Weather Forecasts Institute discovered.

The statement reads: “The unprecedented 2020 northern hemisphere has come to an end.” How is such a thing possible? The finding of the Antarctica ozone hole drove a global action to decrease the use of harmful chemicals that contribute to such changes in the ozone layer. The Arctic hole, however, isn’t related to something we did.

To what the European Space Agency dubbed “unusual atmospheric conditions,” comprising a steady polar vortex of whirling cold air. CAMS defined the 2020 Arctic polar vortex as “exceptionally strong and long-lived.” Shallow temperatures in the stratosphere also had a vital role in the hole’s development. Once the polar vortex lessened up, the hole was able to close.

While the Arctic ozone layer hole is closing itself up, the Antarctica hole is still a concern. But we have good news. NASA declared back in 2018 that the first direct evidence of ozone recovery due to the ban of the chemicals. The 2019 ozone hole was the less prominent on record, but the closing up process is still forecasted to take a few years.
