In 1973, it is proposed that the release of chlorine in the stratosphere might lead to destruction of ozone. This hypothesis and the data just shown were used by Molina and Rowland in 1974 to claim that the CFCs were major sources of stratospheric chlorine, that their continued release would eventually severely deplete the ozone layer, and that this might threaten the very existence of life on earth. In 1984 a remarkable and totally unpredicted phenomenon was discovered by the British Antarctic Survey, the so-called
