The Ozone layer is Now healing - UN report

A new UN report from a study published every four years to monitor the recovery of ozone in the stratosphere has revealed that the ozone layer is healing.

The study, 'Ozone depletion scientific assessment: 2018', which is the latest in a number of reports, shows that the concentration of ozone depleting substances continues to decline, leading to an improvement in the team since the previous assessment carried out in 2014.

The results that have been considered as a demonstration of what global agreements can be achieved and an inspiration for more ambitious climate action to stop a catastrophic increase in world temperatures comes from an internationally agreed action implemented under the historic Montreal Protocol, which came in over 30 years ago.

The protocol was due to the disclosure that chlorofluorocarbons (CFCs) and other ozone depleting substances - used in aerosols, refrigeration and cooling systems and many other things - punch a hole in the ozone layer and allow dangerous ultraviolet radiation to flood through.

Ozone is a layer that protects the earth's life from harmful layers of ultraviolet rays from the sun. Ozone in parts of the stratosphere has been restored by one to three percent since 2000 and at expected rates, the northern hemisphere and mid-range ozone are planned to cure completely in the 2030s followed by the Southern Hemisphere in the 2050s and polar regions by 2060 .
