It seems that the year 2020 will not pass peacefully for humans, as it turns out that the hole in the ozone layer over Antarctica has widened the largest in recent years. Which alerts you the most to harmful UV rays.
And according to the scientific journal Science Alert, scientists from In 2019, they revealed that the Antarctic ozone hole had reached its smallest annual peak since monitoring began in 1982, but the 2020 update shows this atmospheric difference.
Y“Our observations show that the 2020 ozone hole has grown rapidly since mid-August, covering most of Antarctica, with a size well above average,” said project director Diego Loyola of the German Space Center.
New satellite measurements appear From the European Space Agency, that the ozone hole reached its maximum size, which is around 25 million square kilometers, on October 2 of this year, andThis places it at roughly the same estimates as the ozone holes of 2018 and 2015, which recorded respectively 22.9 and 25.6 million square kilometers.
YAtmospheric scientist Vincent Henri Piusch of the European Center for Medium-Range Weather Forecasting said: “There is a lot of variation in the evolution of ozone hole events each year … The ozone hole of 2020 looks like a hole in 2018, which was also a very large hole. ”
In addition to fluctuations from year to year, the ozone hole over Antarctica is shrinking and growing annually, andThis happens when polar stratospheric clouds form at temperatures below -78 ° C (-108.4 ° F), as chemical reactions destroy ozone molecules in the presence of solar radiation.
With the return of sunlight to the South Pole in recent weeks, the layer has witnessed a depletion of the ozone layer over the region, confirming the need Continue to apply the Montreal Protocol that prohibits the emissions of chemicals that deplete the ozone layer.The Montreal Protocol marked a milestone in humanity’s environmental advancements, phasing out the manufacture of harmful CFCs, previously used in refrigerators, packaging, and aerosols, which destroy ozone molecules in sunlight.
