The Earth’s ozone layer could be restored, scientists

Озоновый слой Земли может восстановиться - ученые

Since 2000, the ozone layer outside the polar regions is restored by 1-3% for decades.

Subject to the requirements of the Montreal Protocol that bans the production of ozone-depleting compounds, the ozone layer of the atmosphere in the Northern hemisphere will fully recover until 2030, and the planet Earth in 2060. This is evidenced by the research of the world meteorological organization (WMO).

In late 1970, it was discovered the depletion of the ozone layer, but by the early twentieth century it stopped. Scientists partly attribute this to global warming and increased concentration of carbon dioxide (CO2) in the atmosphere. Also stop its depletion is associated with positive consequences of signing the Montreal Protocol.

According to the WTO, since 2000, the ozone layer outside the polar regions is restored by 1-3% for decades. If these rates continue, in the Northern hemisphere and mid-latitudes he recover until the 2030-ies in the southern hemisphere – until 2050-ies, and in the polar regions until 2060.

The report noted that, despite the restrictions of the Montreal Protocol, production of hazardous to the ozone layer refrigerants stopped everywhere, including in the spring of 2018, scientists have recorded increases in emissions of refrigerant chlorofluorocarbons CFC-11, which tied with the unregistered production in Asia.

Earlier, a group of American scientists warned of a likely appearance at the US giant ozone hole.
