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 ...

Scientists have detected rapidly rising levels of five ozone-damaging chlorofluorocarbons, or CFCs, in the atmosphere. These are harmful chemicals have been banned globally since 2010 because of the ...

A recent increase in a number of ozone-depleting chlorofluorocarbons (CFCs) poses a climate threat, scientists say. Five ozone-depleting chlorofluorocarbons significantly increased in the Earth's ...

Monitoring the expected decline in the atmospheric concentrations of banned compounds might seem like an unexciting research task. But in a paper in Nature, Montzka et al. 1 report an unexpected ...

The transition from CFC to HFA propellants is occurring because of public health concerns about the detrimental effects of CFCs on stratospheric ozone levels. In 2005, the Food and Drug Administration ...

China has moved to ban the production of ozone-depleting chlorofluorocarbons (CFCs), according to a statement from the country’s environmental protection agency. The action is in accordance with the ...

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 ...

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 ...

Researchers at MIT have discovered that ozone-depleting chlorofluorocarbons known as CFCs stay in the atmosphere for less time than previously estimated. CFCs were phased out globally in 2010, and the ...

NEW YORK — Every year, diplomats gather to review progress in implementing the Montreal Protocol, a 1987 treaty that limited global use of chlorofluorocarbons and other ozone- eating chemicals. This ...
