Chlorofluorocarbons were also used commonly in refrigerators, air conditioners, and for many industrial applications. Chlorofluorocarbons were particularly popular because they are non-flammable, non-toxic, and non-reactive to most compounds. However, after scientists began to observe that the Earth’s ozone layer was thinning beyond normal seasonal variations, in 1974, Nobel Prize winner Dr. F. Sherwood Rowland and Dr. Mario Molina discovered that these chlorofluorocarbons were the likely cause of the damage to the ozone layer, though this wasn’t conclusively proven until 1984.
