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 ...

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

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 ...

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 ...

So, there’s still a long way to go before atmospheric ozone is back to the levels before the advent of widespread CFC ...

Since then, a worldwide agreement has been reached to reduce emissions of chlorofluorocarbons (CFCs ... (WMO), the area affected by the ozone hole reached its peak this year on Sept.

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 ...
