Published July 1988 through June 1999
FROM VOLUME 9, NUMBER 5, MAY 1996
CFCs confirmed: A new study based on satellite observations claims to show
beyond a reasonable doubt that anthropogenic CFCs dominate ozone depletion in
the lower stratosphere. (See Russell paper, Prof. Pubs./Gen. Interest, this Digest
Antarctic ice stability is the subject of several papers listed in
Prof. Pubs./Earth System Science, this issue. The paper by Vaughan and Doake of
the British Antarctic Survey describes a 50-year trend of retreating ice shelves
in some regions of the Antarctic. They and other scientists discuss the
implications of their findings in "Ice Shelves Melting as Forecast, but
Disaster Script Is in Doubt" (The New York Times, p. C4,
Jan. 30, 1996).
CFC destruction: Yale researchers have discovered a process which
could lead to a very cheap and easy way to destroy CFCs. (See Burdeniuc paper in
Prof. Pubs./Ozone Depletion/CFCs, this Digest issue--May 1996.) If a
commercial process can be developed, it would increase the incentive for
industries and developing countries to destroy CFCs banned under the Montreal
Protocol, rather than releasing them to the atmosphere. It could also hasten the
phaseout of CFCs, and provide a method for destroying contaminated CFCs that
cannot be recycled. See (all 1996): New Scientist, p. 24, Jan. 27; Science
News, p. 36, Jan. 20; Intl. Environ. Rptr., pp. 106-107, Feb. 7.
Coral Beaching: Correspondence to Nature (p. 396, Apr. 4,
1996) reports data demonstrating for the first time that coral bleaching is
caused by a bacterial infection; seawater temperature is a contributing factor.
