The ozone layer has been recovering since 1987
Today’s Video of the Day from NASA Goddard describes the recovery of the Earth’s ozone layer since legislation was passed in 1987 to protect it.
This year, colder temperatures in the South Pole region of Antarctica caused the ozone hole to grow slightly larger compared to 2016 and 2017.
However, models developed by NASA scientists have revealed that the 2018 hole is still much smaller than it would have been without the Montreal Protocol, which banned the use of harmful chlorofluorocarbons (CFCs) that were depleting the ozone layer.
