Just as the sea ice around Antarctica grows and shrinks each year, ozone hole also grows and shrinks. Interestingly this year, this hole has grown a lot. According to reports, the ozone hole over Antarctica three times that of Brazil reached its size.
European Space AgencyObservations taken from ESA’s (ESA) Copernicus Sentinel-5P satellite indicate that the ozone hole will close on September 16, 2023 at approximately 26 million square kilometers It shows that you have reached an area. These results make the hole one of the largest seasonal holes ever observed. The largest ozone hole occurred in 2000, when it reached an area of 28.4 million square kilometers.
Ozone is a naturally occurring gas and is found in the stratosphere, the layer that protects us from the sun’s ultraviolet, or UV, rays. In 1985, a hole in the ozone layer was discovered over Antarctica and was later linked to humans’ use of decarbonizing substances. The use of these substances has since been banned and the size of the hole has been closely monitored.
It may return to its former state in 2050
However, the ozone hole continues to grow and shrink seasonally due to temperature changes and wind conditions in the stratosphere, reaching its maximum between mid-September and mid-October. Copernicus Atmospheric Monitoring Service senior scientist Antje Inness In his statement, “Our operational ozone monitoring and forecasting service shows that the 2023 ozone hole has been growing rapidly since mid-August.” said.
According to scientists, higher than normal growth may occur Reasonwhich occurred in January 2022 and caused large amounts of water vapor to enter the air. Hunga Tonga volcanic eruption it could be. Water vapor is thought to cause chlorofluorocarbons (CFCs) to react, accelerating the depletion of the ozone layer.
On the other hand, despite a large seasonal growth, the size of the ozone hole continues to decrease overall. ESA’s Copernicus Sentinel-5P mission manager Claus Zehner, “Thanks to the Montreal Protocol and the reduction of human-caused ozone-depleting substances, scientists now estimate that the global ozone layer is about by 2050“The screen is expected to reach its normal state again.” said.
