The global treaty that protected the Earth's ozone layer did more than just maintain a crucial protective covering for our planet. The treaty known as the Montreal Protocol on Substances That Deplete the Ozone Layer phased out the use of chlorofluorocarbons -- deadly, ozone-eating industrial chemicals. Beyond allowing the ozone layer to recover, the international agreement also had a range of other health benefits. Scientists now believe that the accord also helped to mitigate the impact of global warming. “The [Arctic] warming will not be as great as it would have been without the Montreal Protocol,” study co-author Michael Previdi, a climate scientist at Columbia University, told Scientific American.
