The ozone hole over the Antarctic record has decreased over the last year. She could be one of the lowest in the last three decades – its size is just over 5 million square meters.
As BBC reports, citing scientists from the data Service monitoring of the atmosphere, the increase of the ozone hole this year started earlier than usual.
The process was stopped due to climate change, i.e. warming that raised the temperature in the stratosphere at 20-30 degrees. That’s what destabilized the process of destruction of ozone.
As told Deputy Chairman of the European Agency CAMS Richard Engelen, this figure is encouraging, but all too happy and do not relax.
The ozone hole has decreased to a record
“Now we have to consider this phenomenon as an interesting anomaly. We need to know more about what it was called,” explained Engelen.
He also added that the reduction of the ozone hole is not related to the Montreal Protocol, under which mankind has tried to reduce the content of chlorine and bromine in the atmosphere. The scientist explained that these substances are still in the air.
“It is obvious that people will start to ask questions related to climate change, but until we have answers,” – said the Deputy head CAMS. According to the report of the world organization of Metrology in 2018, ozone layer recovery to the level prior to 1970 can only be expected in 2060.
