NASA reveals shocking image of the gigantic ozone hole over Antarctica | VIDEO

The situation is dire. During this year, a gigantic ozone hole has opened over Antarctica, which reached a maximum extension of 24.8 million square kilometers. Scientists from the POT and the National Office of Oceanic and Atmospheric Administration assure that the low temperatures increased this phenomenon.

According to a press release from the Earth Observatory from NASA, the hole is the thirteenth largest since 1979; it could close at the end of November. In a video, NASA showed the immensity of the hole over the South Pole between January 1 and October 7, 2021. “Colder-than-average temperatures and strong winds in the stratosphere surrounding Antarctica contributed to its size ”, the experts explained.

What is an ozone hole?

An “ozone hole” is a thinning of the ozone layer in the stratosphere over Antarctica that occurs every September. Chemically active forms of chlorine and bromine are released into the stratosphere during reactions in high-altitude polar clouds. The reactive chlorine and bromine then initiate ozone-depleting reactions when the Sun rises in Antarctica at the end of winter, according to NASA.

“This is a big ozone hole due to the stratospheric conditions of 2021, cooler than average, and without the Montreal Protocol it would have been much higher,” he said Paul Newman, cChief Earth Science Scientist at NASA’s Goddard Space Flight Center.

To prevent the holes from growing over the years, there is something called “The Montreal Protocol”, Done in 1987, which restricts substances that deplete the ozone layer, but only 50 nations have signed it; When he made the deal, scientists predicted that the ozone layer would recover in 2060 if more nations joined, which it has not. Recovery is being slower than anticipated and the consensus now appears to be that it will not be before 2070 due to human activity and climate change.
