Given that some ozone-depleting substances also function as greenhouse gases, their phaseout is an added bonus for the climate, it says, whilst stressing the need for continued monitoring and to avoid ...

The ozone layer sits toward the bottom of the stratosphere, roughly 20 to 40 kilometers (66,000 and 131,000 feet) above the ground.

There was a time, not so long ago, when the depletion of Earth’s ozone layer seemed like an insurmountable challenge. Decades of using harmful chemicals, such as chlorofluorocarbons (CFCs), had ...

The ozone layer is a trace gas in the stratosphere, one of the four layers of the Earth's atmosphere. It functions as a protective gas shield that absorbs ultraviolet radiation, protecting humans ...

"There is a very slow recovery, but we’ll still have ozone holes for another 50 years or more." Indeed, though the Antarctic ozone hole shows signs of recovery, the healing process is very slow.

Conclusive proof of a recovery in the ozone layer could be decades away, scientists say, and some areas, such as the area over the Canadian Arctic, are still at risk.

That ban, agreed under the Montreal Protocol, is widely considered to have been effective in aiding the ozone layer’s recovery. But the hole, which grows over the Antarctic during spring before ...

Celebrating the International Day for Preservation of Ozone Layer with the theme of ‘Montreal protocol: fixing the ozone layer and reducing climate change ’ at functions organized by the ...

A United Nations report released on Monday, Nov. 5, 2018 says Earth's protective ozone layer is finally healing after aerosol sprays and coolants ate away at it. (NASA via Associated Press) ...
