According to a new assessment report on Montreal protocol, the earth’s protective ozone layer is well on track to recovery. The report released by the UN environment programme and the world meteorological organization (WMO), presents scientific evidence showing continuous decrease in concentration of ozone-depleting substances at a certain rate since 2000.
According to the reports, the ozone layer will be healed over the Polar Regions by 2060, while the damage done over the Southern Hemisphere should be completely erased by sometime in the 2050s. The ozone layer over the Northern Hemisphere and mid-latitude regions, meanwhile, is expected to be entirely patched up sometime in the 2030s.
