Adopted 35 years ago, the Montreal Protocol remains a groundbreaking environmental agreement, credited with saving millions ...

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

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 ...

The current reduction in the ozone hole stems from a combination of declining chlorofluorocarbon (CFC) levels and unexpected ozone infusions from air currents north of Antarctica. The Montreal ...

According to the results of a study, climate change will worsen air pollution, increasing ground-level ozone. How will this ...

In 2024, the ozone hole over the Antarctic showed a notable reduction in size, ranking as the seventh smallest since monitoring began post-Montreal Protocol. This improvement is credited to ongoing ...

Chemicals called chlorofluorocarbons, which are made up of chlorine, fluorine and carbon atoms, are the biggest culprit in ozone depletion. More commonly known as CFCs, they can be found in ...

Although that is still significant, it is the 20th smallest hole since records began in 1979 and the seventh smallest since ozone-depleting CFCs were banned under the Montreal agreement.

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 ...

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

During the fall of 2024, NOAA estimated the hole in the ozone layer above Earth’s South Pole was the seventh smallest since monitoring began in 1992. Scientists attributed some of the improvement to a ...

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 ...
