Summary of scientific research
Prof. Molina predicted in 1974 (together with F.S. Rowland) that CFC gases being used in spray cans, as refrigerants and solvents, etc., would eventually deplete the ozone layer. This laid the ground for the discovery of the 'ozone hole' over the Antarctic. Subsequent work in large measure explained the mechanism by which ozone depletion over the poles comes about.
