Scientists Have Announced That The Largest Arctic Ozone Hole Has Probably Closed Itself

Largest Arctic Ozone Hole

The past months were probably the hardest ones for every human being on Earth. So, after all the bad news that we receive every day, for change, we can hear a piece of positive information. Probably that is the thing that we all need currently. Well, that is what we have right now, a piece of good news. In the past days, scientists have noticed something fascinating. They said that a gigantic hole in the Arctic ozone layer is now closed.

In the pictures that NASA Ozone Watch has shared, we can see that the large hole in the ozone layer is located on the top of the northern part of Earth. Fortunately, only after one month, the holes were closed. The main reason for closing the gap is the positive outcome of the coronavirus pandemic quarantine on Earth. The pollution levels were way too high before the pandemic, and now, when all the people are in lockdown, there is no traffic, no pollution, and Earth is repairing itself. Maybe the COVID-19 situation is an Earth’s time when everything that we have damaged is to be repaired.

You can see a photo that shows the ozone layer snapped at the beginning of March.

But, the latest photos that were published by NASA were not the same. The scientists from Copernicus. Atmosphere Monitoring Service-CAMS say that the healing of the ozone layer has happened. According to the scientists, a polar vortex (representing a sizeable low-pressure zone consisted of swirling cold air) is what has created the thinning of the layer. The polar vortex was monitored for a couple of weeks in March and resulted in trapping the cold air in the North Pole. There were formed the high altitude clouds, and the chemical reaction forced the depletion of the ozone layer if exposed to the light of the sun.

Nowadays, the polar vortex is starting to die down, so the ozone levels and values are for sure, getting back to normal because the last photos are showing the vanishing of the hole. According to the information that was published by NASA, the hole reached its peak on March 26.

Only one month later, on April 26, the images show something fascinating and different. The hole is closed completely.

Nevertheless, human activity has nothing to do with this situation, and the scientists said that we have been making some remarkable positive impact in the last couple of decades. The Montreal Protocol in 1987 has set out goals, that the scientists are following to lower the human-made chemicals that are damaging the ozone layer. As a result of that, the enormous hole in the ozone layer located in the southern hemisphere is shrinking. The first time that the hole was noticed was in 1985.

Copernicus ECMWF on their Twitter account shared some additional info about particular this matter.

Furthermore, maybe human Nature did nothing to help to close the ozone layer, but the quarantine because of the coronavirus pandemic, has for sure, influenced on Earth and Nature. For example, the waters in Venice are clear, and we can see fish inside. That is a consequence of the travel bans by the government and the lockdown.
