A new study suggests the Montreal Protocol - the 1987 agreement to stop producing ozone depleting substances (ODSs) - could be responsible for pausing, or even reversing, some troubling changes in air currents around the Southern Hemisphere.

With the declining levels of ozone-destroying chlorine, scientists have for the first time observed less ozone depletion.

NASA scientists have found significant proofs that ozone layer on Earth is shrinking or healing itself; though it will take more than half a century to fully recover.

The Brazilian government has received over $4.8 million for continuing their actions to protect the ozone layer, officials said.

Amid rising temperature over Antarctica, a hole in Earth's ozone layer has shrunk to smallest since 1988, announce scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA).

As per the findings in the study, on several occasions and several locations, between February and May 2017, the ozone concentration was found to be very high - 3.4 times the normal standard.
