A Mystery Solved
2012 March 12. F. Sherwood Rowland, Cited Aerosols's Danger, Is Dead at 84 | By Felicity Barringer, The NY Times. Excerpt: F. Sherwood Rowland, whose discovery in 1974 of the danger that aerosols
posed to the ozone layer was initially met with disdain but who was
ultimately vindicated with the 1995 Nobel Prize in Chemistry, died on Saturday at his home in Corona del Mar, Calif....
...Industry representatives at first disputed Dr. Rowland’s findings, and
many skeptical colleagues in the field avoided him. But his findings,
achieved in laboratory experiments, were supported 11 years later when
British scientists discovered that the stratospheric ozone layer, which
blocks harmful ultraviolet rays, had developed a hole over Antarctica.
The discovery led to the 1987 Montreal Protocol,
a landmark international environmental treaty to stop the production of
the aerosol compounds known as chlorofluorocarbons, or CFC’s, and other
ozone-depleting chemicals and to eliminate inventories of them....
