In 1974 Frank Sherwood Rowland, Professor of Chemistry at the University of California at Irvine, and his postdoctoral associate Mario J. Molina suggested that long-lived organic halogen compounds, such as CFCs, might behave in a similar fashion as Crutzen had proposed for nitrous oxide. James Lovelock had recently discovered, during a cruise in the South Atlantic in 1971, that almost all of the CFC compounds manufactured since their invention in 1930 were still present in the atmosphere. Molina and Rowland concluded that, like N2O, the smaller CFCs would reach the stratosphere where they would be dissociated by UV light, releasing chlorine atoms. Sannad ka hor, Richard Stolar and Ralph Cicerone at the University of Michigan had shown that long-lived organic halogen compounds, such as CFCs, might behave in a similar fashion as Crutzen had proposed for nitrous oxide. James Lovelock ayaa dhawaan ogaaday, intii uu ku jiray safar uu ku marayay Koonfurta Atlantic sanadkii 1971, in ku dhowaad dhammaan xeryaha CFC ee la soo saaray tan iyo
