Nov. 21, 2023 — Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years; researchers believe chlorofluorocarbons (CFCs ...

Under the Montreal Protocol, CFCs have been phased out to ... soar due to climate change, the chemical reaction responsible for producing the ozone gas is accelerated. The European Geosciences ...

The ozone hole over the Antarctic could fully mend by 2066, according to the National Oceanic and Atmospheric Administration ...

For the first time, researchers have observed how bromoform rearranges its atoms in less than a trillionth of a second after ...

The improvement is due to a combination of continuing declines in harmful chlorofluorocarbon (CFC) chemicals, along with an unexpected infusion of ozone carried by air currents from north of the ...

The recent improvement is the result of declining chlorofluorocarbons (CFCs), a chemical that’s harmful to the ozone and was phased out by the Montreal Protocol. The measure was signed in 1987 to ...

The Montreal Protocol changed everything. Once destructive CFCs are now fading from the atmosphere, letting the ozone slowly rebound. This is a testament to global cooperation in action ...

Compounds with a chlorine or bromine moiety (e.g., halothane, isoflurane, chlorofluorocarbons) can deplete the atmospheric ozone layer, resulting in increased ultraviolet radiation reaching the earth.
