In early 2020, a huge hole was detected in the Arctic ozone layer. However, everything seems to indicate that it has been closed.
In early 2020, a huge hole was detected in the ozone layer in the Arctic. It has been classified as the largest one that has been detected. The news was released by the Copernicus Atmospheric Monitoring Service (CAMS), an institution that classified this phenomenon as something quite unusual. Now, news has spread that this hole has been closed.
The hole was the result of a very sharp Arctic polar vortex . It is worth saying that it is something that happens naturally. However; Due to contamination, the size of these holes, caused by polar vortices, is quite large.
WHAT IS A POLAR VORTEX?
It is an area of low pressure and icy air , which borders both poles of the earth. Such vortices have always existed. As expected, they usually disappear in the summer and become stronger in the low winter temperatures.
The Arctic polar vortex is weaker than the Antarctic . The reason? Well, thanks to the proximity of land masses and mountain ranges. Such geographical elements minimize the cold in this region.
THE OZONE LAYER AND ITS IMPORTANCE FOR LIFE
This layer is located about 15 or 35 kilometers from the planet’s surface. Its mission is to create a barrier against ultraviolet rays .
Pollution has wreaked havoc on this layer. CO 2, as well as other emissions are what harm it . For example, a chemical component has been found to damage the ozone layer without realizing it . It is a paint thinner that is widely used.
There is no doubt that it is time to become aware. If ultraviolet rays penetrate into ecosystems, the damage would be terrible. On plants the effect would be lethal, as well as on living beings.
Furthermore, humans are a very sensitive species to such rays . We must remember that our skin is not covered by a layer of fur or feathers, so our epidermis is 100% exposed to ultraviolet radiation.
INACTIVITY DUE TO CORONAVIRUS AND OZONE LAYER
Recent information indicates that the hole in the ozone layer is reduced . This is how low industrial activity induces less polluting emissions. It is striking that, with only a few months in quarantine, improvement is already noticeable in the ozone blanket that surrounds the planet .
Although the hole in the Arctic appeared through a natural vortex, everything indicates that its size was not at all unusual. In such a case, the contamination causes the polar vortices to lead to larger diameter openings in the ozone.
It is evident that the ozone layer recovers quickly. The pandemic has allowed a time of testing to prove that lowering contamination aids recovery.
