European and Australian researchers have identified three new ozone-depleting chlorofluorocarbons, dubbed CFC-112, CFC-112a, CFC-113a, and one new ozone-depleting hydrochlorofluorocarbon, HCFC-133a, in the atmosphere of our planet. Scientists have discovered four new man-made gases – CFC-112, CFC-112a, CFC-113a and HCFC-133a – all of which are contributing to the destruction of the ozone layer. Image credit: NASA.
