Published in Nature, Sherwood Rowland and Mario Molina's research linked CFCs to the depletion of Earth's ozone layer. Initially utilized for their stability and nontoxic properties, CFCs were ...

Although that is still significant, it is the 20th smallest hole since records began in 1979 and the seventh smallest since ...

Most ozone-depleting substances also contribute to global warming. By reining in these substances and protecting carbon sinks ...

Humans have been depleting the ozone layer with chemical products. The unintentional experiment started in the late 1920s, when Thomas Midgley and other industrial chemists began to produce ...

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 ...

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 ...

In contrast to chemicals containing chlorine and bromine, nitrogen oxides destroy ozone globally between 25 and 35 km. Nitrous oxide behaves in a similar way to chlorofluorocarbons (CFCs): it is ...

“Human beings in their activities generated large amounts of CFCs. These gases last for many years and also break down ozone molecules,” she elaborated. Using ozone to manufacture certain ...

From the mid-1970s, chemicals called chlorofluorocarbons (CFCs) — once widely used in aerosols and refrigerators — were found to be reducing ozone levels, creating annual holes largely over ...
