How an Illicit Chemical Is Jeopardizing Recovery of the Ozone Layer…

An international treaty signed in 1987 officially halted production and use of chemicals that deplete the atmosphere’s critical ozone layer. But new research finds a troubling rise in emissions of a banned chemical that is being routinely used in factories in northeast China… Read this article here, at Yale Environment 360: https://e360.yale.edu/features/how-an-illicit-chemical-is-jeopardizing-recovery-of-the-ozone-layer-china Advertisements
