The ozone layer over the Arctic dwindled to a record

The thickness of the ozone layer over the Arctic has decreased to a record level in the atmosphere due to chemicals. This is stated in the report of the World Meteorological Organization of the UN.

It clarifies the "Interfax", the amount of ozone in the Arctic with the onset of winter has decreased by 40%, while in the winter of 2010 it fell by 30%.

According to scientists, the main cause of ozone depletion in 2011 was the action of chemicals and an unusually cold winter. However, experts predict that by 2030, the level of ozone can be restored to the level in 1987, as 196 countries signed the Montreal Protocol to withdraw from the production of chemicals that deplete the ozone layer.
