Study shows Ozone Layer Recovery! Montreal Protocol signed 30 years ago held responsible

Ozone Layer is repairing

The planet’s Ozone Layer is on its way towards full recovery. The study shows, the Ozone Layer, responsible for protecting the planet from harmful radiations, si slowly yet steadily under-recovery. The report, published in the scientific journal Nature, might be a result of 1987’s Montreal Protocol.

The Montreal Protocol was signed on 16 September 1987, designed to prevent ozone layer depletion. The treaty phased out a lot of air polluting substances. But, over the years these substances came back into use.

We are exposed to harmful radiations of the Sun without the Ozone Layer protecting us. Thankfully that’s not the case.

When will Ozone Layer repair fully?

The uncontrolled use of chlorofluorocarbons or CFCs causes ozone layer depletion. This international treaty bans the use of CFCs. Antara Banerjee, the lead author of the study, speaks to a journalist from The Independent regarding her team’s findings. She is a CIRES Visiting Fellow at the University of Colorado Boulder and works at the National Oceanic and Atmospheric Administration (NOAA).

The depleting ozone layer had impacted the air currents that flow towards both the North and South Pole. “The movement of these jet streams have stopped since 2000 and might even be reversing,” she said. Around the same time, Antara said the “CFCs from spray cans and refrigerants started to decline”.

She said that climate change actions, if well planned, do work and “we can reverse the damage that we’ve already done to our planet”. She thinks the Ozone layer has the capability to fully repair by 2060.

Now, her team hopes that if humans keep following the protocol, the ozone hole might recover fully though the recovery at different regions would happen at a different pace. Ozone Layer recovery comes as a piece of good news in current stressful times.
