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 new study published in the journal Atmospheric Chemistry and Physics reveals a 17-year delay in the projected recovery of ...

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 ...

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 ...

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 ...

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 ...

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 ...

a Harvard University professor of atmospheric chemistry best known for establishing that chlorofluorocarbons were damaging the Ozone Layer. "The ocean was running almost 10ºC warmer all the way ...

But scientists soon discovered that didn’t matter because these molecules were extremely toxic to the ozone layer! Turns out, when UV light hits a CFC molecule, it releases a chlorine atom which ...
