Summary:

Two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been found in the atmosphere by a group of scientists. Scientists made the discovery by comparing today's air samples with air collected between 1978 and 2012 in unpolluted Tasmania, and samples taken during aircraft flights. Measurements show that all but one of the new gases have been released into the atmosphere in recent years.
