The researchers say the same urgency is needed to combat climate change.

A United Nations study found evidence that the ozone layer, which protects Earth from ultraviolet rays, is beginning to recover after years of depletion.

Scientists believe the good news is the result of a global ban imposed in the 1980s on chlorofluorocarbons (CFCs), the chemicals used in refrigerators and aerosol sprays.

The report’s authors say this is an environmental success story thanks to international action and that the same level of urgency and unity must be directed at tackling climate change.

The biggest hole in the ozone layer is over Antarctica.

“We have started to do the right thing to get the atmosphere back to what it was before the start of the industrial revolution,” NASA scientist Ken Jucks told the BBC.
