In 1976, the National Academy of Sciences released a report entitled Halocarbons: Effects on Stratospheric Ozone. The purpose of this study was to evaluate the likely effect of chlorofluorocarbons (CFC's) on the ozone layer in the atmosphere. A number of publications on the same subject have been prepared since then by different official bodies (NASA, World Meteorological Organization, European communities, the British government, etc.). The opinions expressed in these reports were not always in agreement and even sharply differed in certain cases.
Guy Brasseur (Tue,) studied this question.
