The ozone layer in the Arctic declined to record

Observations by scientists over the past few months show that ozone depletion in the Arctic has reached a record, according to the World Meteorological Organization (WMO).

On April 5, WMO announced: 'Ozone depletion, the shield that protects life on earth from harmful ultraviolet rays, has reached unprecedented levels in the Arctic in the spring, because of its existence. of substances harmful to the ozone layer in the atmosphere and very cold winters in the stratosphere '.

Observations show that the ozone layer in the Arctic has declined by 40% from the beginning of winter to the end of March. Earlier, record ozone depletion at the Arctic was about 30%, occurring in the few winters within 15 years.

Because of this decline, regions in Northern Europe will see ultraviolet radiation levels higher than normal in the next few weeks . WMO advises people in this area to monitor the forecast for ultraviolet rays.

The ozone level in the stratosphere is a natural protective filter against harmful ultraviolet rays from the sun, which can cause sunburn, cataracts, skin cancer and physical damage. object.

According to WMO, the decline in record ozone in the Arctic occurred despite the implementation of the "very successful" Montreal Protocol, which aims to reduce production and consumption of ozone depleting substances, term as chlorofluorocarbon (CFC) .

These substances were present in refrigeration equipment, pesticides and fire fighting equipment, but were gradually phased out.
