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 ...

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 ...

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

Chlorofluorocarbons, along with other chlorine- and bromine-containing compounds, have been implicated in the accelerated depletion of ozone in the Earth's stratosphere. CFCs were developed in the ...

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 ...

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 ...

A gap in the Antarctic ozone layer has impacted the way the waters ... of a chemical compound known as "chlorofluorocarbon-12," or CFC-12, in the southern oceans, the journal Science reports.

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 ...
