The Antarctic ozone layer is currently healing, as a result of global efforts to reduce ozone-depleting substances.

When CFCs drift up into the stratosphere, they can break down ozone under certain seasonal conditions. The following year, those relevations led to the drafting of the Montreal Protocol -- an ...

CFCs and similar compounds are mostly inert (nonreactive ... Sunlight cooks the polluting chemicals in the air, catalyzing chemical reactions that make ozone. Smog levels tend to be highest in the ...

These ozone-depleting gases include chlorofluorocarbons (CFCs), which we've been cracking down on since the global agreement known as the Montreal Protocol was finalized 33 years ago. CFCs ...

The ozone layer over Antarctica, damaged by air pollution decades ago, has fortunately been recovering in recent years. Scientists have observed gradual ozone restoration since the 2000s, but now, one ...

A 1987 ban on CFCs helped slow the process ... triggering a chemical reaction that's highly destructive to the ozone. The study, published last week in the peer-reviewed Geophysical Research ...

chemicals called chlorofluorocarbons (CFCs) — once widely used in aerosols and refrigerators — were found to be reducing ozone levels, creating annual holes largely over the Antarctica region.

These clouds accelerate chemical reactions that break down ... to human health and ecosystems. Caused by chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS).

When CFCs drift up into the stratosphere, they can break down ozone under certain seasonal conditions. The following year, those relevations led to the drafting of the Montreal Protocol—an ...
