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 ...

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 ...

Without the American ban on the use of CFCs in aerosols there would have been far more ozone-destroying chemicals in the atmosphere by this point. The annual hole would have been larger ...

What is the Ozone Layer? The ozone layer is a crucial component of Earth's stratosphere, located between 19 and 30 km above the surface. It plays a vital role in filtering harmful ultraviolet (UV) ...

The 1987 Montreal Protocol, which banned CFCs in a bid to close the hole, is considered a success story for international environmental cooperation. In January, a major UN-backed assessment found ...

Hey, CFCs are banned across the globe as part of the Montreal Protocol, but are we going to let a little something like an international treaty stand in our way of luring economic development to ...

The main cause of this was thought to be chlorofluorocarbons (CFCs), which were once widely used as refrigerants in air conditioners and refrigerators. CFCs are chemically stable, and when ...

Higher levels of trichlorofluoromethane, also known as CFC-11, were showing up in air samples — despite being officially banned worldwide since 2010. Scientists were worried that this surge was ...

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 ...
