The ozone layer is healing, new study finds!!
The ozone layer is continuing to heal and has the potential to fully recover, according to a new study. A scientific paper heralds a rare success in the reversal of environmental damage and shows that orchestrated global action can make a difference.
Antara Banerjee, a CIRES Visiting Fellow at the University of Colorado Boulder , said: “We found signs of climate changes in the southern hemisphere, specifically in the air circulation patterns. The challenge was showing that these changing air circulation patterns were due to the shrinking ozone hole following the implementation of the Montreal Protocol.
“The emissions of ozone-depleting substances that were responsible for the ozone hole – the CFCs from spray cans and refrigerants – started to decline around 2000, thanks to the Montreal Protocol.”
The Montreal Protocol is proof that if we take global and immediate action we can help pause or even reverse some of the damage we’ve started. Yet even now, the steady rise in greenhouse gas emissions is a reminder that one such action is simply not enough.
The study was published in Nature.
