WebApr 10, 2024 · The research, published in Nature Geoscience and led by the University of Bristol and National Oceanic and Atmospheric Administration (NOAA), puts the rise in part down to the chemicals, known as chlorofluorocarbons or CFCs, being used to make other ozone-friendly alternatives to CFCs. This is an exception allowed under the Montreal … WebA certain portion of HCFC molecules released to the atmosphere will reach the stratosphere and be destroyed there by photolysis (light-initiated decomposition). The chlorine …
WebCFCs reach the stratosphere because the Earth's atmosphere is always in motion and mixes the chemicals added into it. CFC molecules are indeed several times heavier than air. Nevertheless, thousands of measurements from balloons, aircraft, and satellites demonstrate that the CFCs are actually present in the stratosphere. WebApr 7, 2024 · Emitting chlorofluorocarbons -CFCs- into the atmosphere is an insidiously dangerous proposition simply because one (only one) chlorine atom can destroy up to 100,000 atmospheric ozone molecules ...
