And according to the science journal Science Alert, scientists in In 2019, they revealed that the Antarctic ozone hole had reached its smallest annual peak since tracking began in 1982, but the 2020 update shows this atmospheric difference.
And“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 manager Diego Loyola from the German Space Center.
AndAtmospheric scientist Vincent Henri Pioch from the European Center for Medium-Range Weather Forecast said, “There is a lot of variation in the extent of the evolution of the 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, which confirms the necessity Continue to enforce the Montreal Protocol banning emissions of ozone-depleting chemicals, andThe Montreal Protocol was a milestone in humankind’s environmental breakthroughs, as it phased out the manufacture of harmful CFCs – chemicals previously used in refrigerators, packaging and aerosols, that destroy ozone molecules in sunlight.
