Study: The ozone layer's healing, could recover fully

Earth's ozone layer, responsible for protecting the planet from Sun's ultraviolet rays, has been healing and might even fully recover, a recent study has revealed. The study, published in the science journal Nature, said that the recovering ozone hole might have been a result of the 1987 Montreal Protocol. An international climate change treaty, the Montreal Protocol called for the phasing out of any substance that might harm the ozone layer.

Without the presence of the ozone-concentrated layer in the stratosphere, almost nothing would be able to survive on the planet. Major depletion of the layer was attributed to the human use of chlorofluorocarbons or CFCs. The international treaty was adopted to ban the use of CFCs.

Antara Banerjee, who is the lead author of the study, spoke to The Independent regarding their findings. She is a CIRES Visiting Fellow at the University of Colorado Boulder and works at the National Oceanic and Atmospheric Administration (NOAA).
