An international research team led by the University of Bremen has detected chlorofluorocarbons (CFCs) in Earth's atmosphere for the first time in historical measurements from 1951—20 years earlier ...
Two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been found in the atmosphere by a group of scientists. Scientists made the discovery by comparing today's air samples ...

The world would be on track for a collapse of the ozone layer and an additional 2.5 degrees Celsius of global warming by the end of the century if it hadn't agreed in the 1980s to ban CFCs, chemicals ...
THE UPPER ATMOSPHERE (WHTM) — On September 25, 1974, Professors Mario Molina and F. Sherwood Rowland published a paper in the science journal Nature which would lead to widespread bans of chemicals to ...
Volcanoes belch an impressive array of organic chemicals into the air, but ozone-depleting chlorofluorocarbons (CFCs) are an insignificant part of that mix, a new study finds. An international team of ...
Chlorofluorocarbons are to blame for global warming since the 1970s and not carbon dioxide, a researcher claims in a controversial new study. CFCs are already known to deplete ozone, but in-depth ...
