Continued declines in ozone-depleting gases are expected to allow for a recovery of the ozone layer, but not until the middle of the 21st century.

Measurements of ozone-depleting gases provide a means by which adherence to international protocols can be assessed.

That's why we are eliminating the use of ozone-depleting gases from the manufacturing process.

Moreover, they argued, more air-conditioners mean more ozone-depleting gases in the atmosphere, which contribute to global warming.

Moreover, they said, the devices can contain ozone-depleting gases that contribute to global warming if released into the atmosphere.

To save it, all countries need to accept limits on their emissions of ozone-depleting gases.

Because ozone-depleting gases typically last 40 to 100 years in the atmosphere, full recovery is not expected to be reached before 2070.

Why has an "ozone hole" appeared over Antarctica when ozone-depleting gasses are present throughout the stratosphere?

Are there regulations on the production of ozone-depleting gases?

Has the Montreal Protocol been successful in reducing ozone-depleting gases in the atmosphere?
