Nobel Prize in Chemistry 1995 "for their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone" : Paul J Crutzen, Mario J Molina and F Sherwood Rowland
Prof. Paul J Crutzen presents "The stratospheric ozone hole : a man-caused chemical instability". The discovery of the spring time stratospheric ozone hole by scientists of the British Antarctic Survey, led by Joe Farman, was one of the greatest surprises in the history of the atmospheric...
