Researchers say that they have pinpointed the major sources of a mysterious recent rise in a dangerous, ozone-destroying chemical. CFC-11 was primarily used for home insulation but global ...
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 ...
As well as the ozone layer, CFC-11 has a warming impact. Researchers estimate that if the use of the chemical continues, it would be the equivalent of CO₂ from 16 coal-fired power stations every ...
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 ...
The ozone hole above Antarctica has been remarkably massive and long-lived over the past four years and chlorofluorocarbons (CFCs) are not the only things to blame, said researchers in their study ...
A collection of human-made greenhouse gases known as ozone-depleting substances (ODSs), including chlorofluorocarbons that can be found in everyday products such as air conditioners, refrigerators ...
The ozone hole over Antarctica is the seventh smallest it’s been since the early 1990s. Recovery began with the Montreal Protocol, which ended the production of all chlorofluorocarbons (CFCs ...
The connection between CFCs and the ozone layer Almost five decades ago, three chemists — Mario Molino, Sherwood Rowland, and Paul Crutzen — warned that chlorofluorocarbons (CFCs) pose a ...
Our use of ozone-depleting substances such as chlorofluorocarbons (CFCs) had torn a hole in the ozone layer that protects us from the sun’s harmful ultraviolet radiation. United Nations ...
