CFC pollutants are largely responsible for the depletion of the ozone layer, causing the ozone hole. CFC pollutant trend is a more hopeful story than the anxiety inducing increase of carbon dioxide.
Canada was well positioned to lead on climate change in 1990, not only by persuasion but by example. Three years earlier, the Montreal Protocol began the global effort to repair the ozone layer, a promise that Canada swiftly translated into action ...

The Montreal Protocol that phased out chlorofluorocarbons (CFCs), for instance, wasn't signed until 14 years after scientists first linked the chemical to holes in the ozone layer. The pace at which world nations have acted may have accelerated with ...

The ozone layer is the only thing protecting us from the sun's harmful ultraviolet radiation, so countries responded quickly in the 1980s when scientists discovered a spreading "ozone hole" over the Antarctic.
It phased out the gases that were destroying the ozone layer, averting potential catastrophe and healing the hole that human activities had opened in our protective layer.

... did something right, and it's finally paying off. In 1987, most of the world signed on to the Montreal Protocol, which banned the use of CFCs - chemicals such as those emitted by aerosols and old refrigerators - which deplete the protective ozone ...

As well as ozone protection, there was a climate benefit from phasing-out the CFCs because they are much stronger greenhouse gases than carbon dioxide.
The new images confirmed that the ozone accumulates in the polar vortex, as scientists believed, where there's little water vapor; the hydrogen and oxygen molecules can destroy the ozone layer. The ozone turned out to extend further into the springtime ...
Most people think of it solely as a good gas, the essential ingredient in the ozone layer where, high above the planet in the stratosphere, it shields us from harmful ultraviolet light.
Kudos for doing the job, but now, for all our sakes, please depart. That's the message the world has given to hydrofluorocarbons (HFCs), the chemicals that saved the ozone layer but turned out to be an escalating threat to the climate. HFCs became ...
HFCs don't harm the ozone layer like chlorofluorocarbons and similar gases that were eliminated under the 1987 Montreal Protocol.

Earth's falling temperature would cause, among other things, less rain - nine per cent less than usual five years after the strikes - which would have an effect on crops, combined with increased frost.
A fire that destroyed the collective's studio in 1978 swallowed in its flames "Aerosol Arsenal," created soon after scientists discovered that the canned products harm our ozone layer. In 1975, the group had collected as many examples as possible ...
"As Republicans, we have designed and implemented careful and balanced governmental regulation that has brought us clean water and clean air, protection of the ozone layer, safety in transportation, and more efficient use of energy." Frankel, who lived ...

"There are still buildings in the country that operate on older model chillers using chlorofluorocarbons (CFCs) as refrigerants, which may be harmful to the ozone layer. Now that there is greater imperative to reduce GHG emissions, environment ...
Kigali - Climate scientists are advocating for realistic commitments that will see nations reach common ground on battling climate change which is becoming a threat to human livelihoods.
A stone statue, the film This is Spinal Tap and the ozone layer all took a beating when Thomas Dolby spent a weekend at Eddie Van Halen's home, as the pop star explains in his new book.
... but they have terrifying consequences at a lesser distance. Gamma ray bursts and supernovae can destroy the protective ozone layer, which will leave the planet vulnerable to ultraviolet radiation from the sun. This creates what is called ground ...
Dr. Chuma Ezedinma, UNIDO Country Representative, made the statement on Monday in Abuja at a two-day "Expert Critique" meeting to review the 2009 Draft National Environmental-ozone layer Protection Regulations. Ezedinma, who was represented by ...
Normally, the ozone layer in the upper atmosphere shields the Earth's surface from harmful ultraviolet light. But a GRB or supernova would quickly eviscerate that layer.
Envoys from nearly 200 nations meet in Kigali next week to discuss ridding the world of HFCs, gases introduced to save the ozone layer only to unwittingly assail Earth's climate. Observers are hopeful that after years of talks, countries are poised to ...
