There is an ongoing healing of the ozone layer, findings of a new UN-backed report released on Monday, have shown.
The study, ‘Scientific Assessment of Ozone Depletion: 2018’, is the latest in a series of reports, released every four years, which monitor the recovery of ozone in the stratosphere.
Ozone is a layer that protects life on Earth from harmful layers of ultraviolet rays from the sun.
The study shows that the concentration of ozone-depleting substances continues to decrease, leading to an improvement in the layer since the previous assessment carried out in 2014.
The findings are being hailed as a demonstration of what global agreements can achieve, and an inspiration for more ambitious climate action to halt a catastrophic rise in world temperatures.
Ozone in parts of the stratosphere has recovered at a rate of one to three per cent since 2000 and, at projected rates, Northern Hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s, followed by the Southern Hemisphere in the 2050s and polar regions by 2060.
This is due to internationally agreed actions carried out under the historic Montreal Protocol, which came into being over 30 years ago.
