Chlorofluorocarbons (CFCs) are also potent greenhouse gases which contribute to climate change.
The US Senate voted to ratify the Kigali Amendment, agreeing on a bipartisan vote to phase down climate-warming HFCs. Now what?
New research shows how the Montreal Protocol protected vegetation, helping keep carbon out of the atmosphere.
HFCs keep refrigerators cool, but when these short-lived climate pollutants leak, they warm the planet.
It was funny at the time — but rereading Ben Elton’s 1989 bestselling satirical novel Stark today is profoundly unsettling.
New research finds that chlorofluorocarbons (CFCs) and other ozone-depleting substances have boosted the effects of climate change in the Arctic.
For several years, emissions of CFCs have been rising, in apparent defiance of a global ban in place since 2010. A new global detective effort has traced the source to two eastern Chinese provinces.
Global CFC-11 levels were rising and no one knew why. Scientists turned detective to pinpoint the source.
Almost 30 years ago the world responded to the realisation that our ozone layer was in trouble. The resulting Montreal Protocol was a rare example of global cooperation, but there’s no room for complacency.
Earth’s ozone layer shields us from harmful ultraviolet radiation. Nations have been working to reduce ozone-depleting chemicals since the 1980s, but recent studies show that there is still work to do.
As if having asthma wasn’t bad enough news, your health condition is probably contributing to climate change.
Australia has ratified an agreement to phase out hydrofluorocarbons, a manmade compound once hailed as the saviour of the ozone layer. What went wrong?
The Montreal Protocol is finally closing the hole in the ozone layer.
The treaty to limit the destruction of the ozone layer is hailed as the most successful environmental agreement of all time. Three decades on, the ozone layer is slowly but surely returning to health.
While many people are willing to happily gamble with pharmaceuticals, which may offer the most trivial of benefits, they are not ready to believe the facts on climate change.
While the gases most responsible for global warming - carbon dioxide, methane and nitrous oxide - continue to climb, other industrial greenhouse gases are being brought gradually under control.
What the Montreal Protocol has done for the ozone hole threat other international accords could do for climate change – if we all agree.
Much has been made of the domestic political roadblocks between US President Barack Obama and climate action. But by using existing treaties he can get around the hostile Congress and help cut global emissions.
Little-studied synthetic gases could have large effects on the ozone layer and climate if their use goes unchecked, according…
