Ozon layer depletion
Impact
What is the stratospheric ozone layer?
Stratospheric ozone protects the earth’s surface from damaging short-wave ultraviolet radiation. Ozone is generated in the upper stratosphere from short – wave sun radiation, which together with chemical reactions dissociates the ozone again to create a dynamic balance between generation and loss.
The dramatic depletion of stratospheric ozone in the Polar Regions is caused by a combination of anthropogenic emissions of ozone depleting substances, stable circulation patterns, extremely low temperatures and solar radiations.
Conventions
Vienna Convention on Protection of the ozone layer -1985 and the Montreal Protocol on substances that deplete the ozone layer - 1987
