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.

These ozone-depleting gases include chlorofluorocarbons (CFCs), which we've been cracking down on since the global agreement known as the Montreal Protocol was finalized 33 years ago. CFCs ...

Humans have been depleting the ozone layer with chemical products. The unintentional experiment started in the late 1920s, when Thomas Midgley and other industrial chemists began to produce ...

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 ...

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 ...

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 ...
