See how the giant ozone hole over Antarctica grew in 2021 in this NASA video

| Hole over Antarctica grew in 2021 |
The depletion of the ozone layer in the NASA video is monitored by three satellites operated by NASA and the National Oceanic and Atmospheric Administration (NOAA) : Aura, SuomiNPP and NOAA20.
NASA issue new Antarctic ozone video Ozone is a naturally show compound of oxygen (which humans can also produce) that forms high in the highest atmosphere of the earth. It occurs when ultraviolet radiation from the sun interacts with molecular oxygen in our atmosphere.
The resulting ozone acts in a certain way as a sunscreen and protects the earth's surface from ultraviolet ion beams.Unfortunately, chlorine and bromine produced by human activities erode the ozone when the sun rises over Antarctica after the polar winter, as solar radiation stimulates erosion in that region. most of the nations of the world are not signatories; at least part of this majority does not abide by the protocols.
This year's ozone hole reached a maximum size about the size of North America, or 9.6 million square miles (24.8 million square kilometers). NASA found out in mid-October. Had the Montreal Protocol not come into effect, and assuming the levels of atmospheric matter from the early 2000s, the hole would have been about 1.5 million square miles (about four million square kilometers) larger, she added.
When the protocol was signed, the scientists suggested that the ozone layer would recover in 2060, but the recovery is slower than expected and the consensus now does not appear to be before 2070, said Vincent Henri Peuch, director of the Copernicus Atmosphere Monitoring Service The European Union.
Summary:
- NASA difficulty new Antarctic ozone video Ozone is a certainly display compound of oxygen (which human beings also can produce) that bureaucracy excessive withinside the maximum surroundings of the earth.
- The ensuing ozone acts in a sure manner as a sunscreen and protects the earth's floor from ultraviolet ion beams.
- Unfortunately, chlorine and bromine produced with the aid of using human sports erode the ozone whilst the solar rises over Antarctica after the polar winter, as sun radiation stimulates erosion in that region.
- Had the Montreal Protocol now no longer come into effect, and assuming the degrees of atmospheric count number from the early 2000s, the hollow could were approximately 1.
- five million rectangular miles (approximately 4 million rectangular kilometers) larger, she added.
