The World Solved the Ozone Problem. It Can Solve Climate Change.

Nearly 50 years ago, three chemists named Mario Molina, Sherwood Rowland and Paul Crutzen found evidence that chlorofluorocarbons, chemicals known as CFCs and released from aerosol sprays, were weakening the ozone layer that functions as the earth’s natural sunscreen protecting humans, animals and plants from harmful radiation.The discovery made big news and rattled the public.…
