Just after the year of research of diminishing of the ozone hole, again it is discovered that it has been increased to its “maximum size” this year.
The World Meteorological Organization announced on Tuesday that
the hole, which arises annually, rose “rapidly” from mid-August and peaked in early October at about 9.2 million square miles,
According to WMO
It is at its “deepest and largest” size in recent years and was driven by a strong, strong and frigid polar whirlpool, which kept the climate of the ozone layer over Antarctica unfailingly cold.
•The polar stratospheric clouds comprise ice crystals that can turn non-reactive compounds into reactive ones, an important role in the chemical destruction of the ozone, which protects Earth from the harmful ultraviolet rays of the sun.
•Ozone depletion is promptly associated with the climate in the stratosphere, as polar stratospheric clouds only form at temperatures below -78 degrees Celsius.
•Last year at this time, scientists were very happy to publish that the void had shrunk to its tiniest size since it was observed.
Unusual Antarctic conditions were accountable for the happening rather than procedures to reduce fuel emissions, according to NASA.
Companions such as the Copernicus Atmospheric Monitoring Service, NASA and the Environment and Climate Change Canada are working with WMO in the research and monitoring of ozone holes.
This year’s void matches the one that shaped in 2018, which was also a significant size. The director of Copernicus Atmosphere Monitoring Service, Vincent-Henri Peuch, said in a statement that there is much variability in how far ozone hole events develop each year.
Now the International Montreal Protocol law of 1987 should be enforced which bans emissions of harmful ozone-depleting chemicals.
According to WMO the data clearly show a trend in decreasing area of the ozone hole. A scientific examination published by the WMO and the United Nations in 2018 said that the ozone layer has a tendency to reimburse to pre-1980 levels over Antarctica by 2060.
