When CFCs drift up into the stratosphere, they can break down ozone under certain seasonal conditions. The following year, those relevations led to the drafting of the Montreal Protocol -- an ...

Researchers quickly traced the cause to human-made ozone-depleting substances (ODS), particularly chlorofluorocarbons (CFCs), ...

In 1990, Margaret Thatcher urged further support for the Montreal Protocol so that CFCs could be phased out completely and developing nations could afford ozone friendly technologies.

Testing simulations based on different climate factors, researchers seemingly confirmed that efforts to limit the emission of chlorofluorocarbons (CFCs) — chemicals that contain carbon, chlorine, and ...

In the 1970s and ‘80s, it became apparent that a gaping hole in the ozone layer was being formed over Antarctica. This depletion was primarily attributed to chlorofluorocarbons (CFCs ...

Researchers found evidence that quickly confirmed the ozone hole's cause - chlorofluorocarbons, or CFCs, which are chemicals that were then used in refrigeration, air conditioning, insulation ...

The study suggests that the reduction of ozone depleting substances, called chlorofluorocarbons (CFCs), is indeed the primary driver behind the healing ozone hole. This finding is more than just ...

Nov. 21, 2023 — Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years; researchers believe chlorofluorocarbons (CFCs ...

From the mid-1970s, chemicals called chlorofluorocarbons (CFCs) — once widely used in aerosols and refrigerators — were found to be reducing ozone levels, creating annual holes largely over ...

When CFCs drift up into the stratosphere, they can break down ozone under certain seasonal conditions. The following year, those relevations led to the drafting of the Montreal Protocol—an ...
