OZONE DEPLETION: POLICY

Item #d96sep19

"Potential Environmental Impacts of Future Halocarbon Emissions," K.J. Holmes (Dept. Geog., Johns Hopkins Univ., Baltimore MD 21218), J.H. Ellis, Environ. Sci. & Technol., 30(8), 348A ff., Aug. 1996.

Reports an analysis which integrates all major components of the problem: demographic, economic, and regulatory processes; technological factors that translate production into emissions; and environmental processes that determine impacts. If even a small percentage of nations continues to expand halocarbon production at modest rates, the ozone hole will not be eliminated. Continued use of small amounts of ozone-depleting substances for essential uses and the failure to adequately replace all of them can eliminate the possibility of returning the atmosphere to pre-ozone hole conditions.

Item #d96sep20

"The Ozone Layer: The Road Not Taken," M. Prather, (Dept. Earth System Sci., Univ. California, Irvine CA 92717), P. Midgley et al., Nature, 381(6583), 551-554, June 13, 1996. (See Global Climate Change Digest, Prof. Pubs./Of Gen. Interest, July 1996.) A follow-up article under the same title, by S.O. Andersen, appeared in Nature, 382(6590), 390, Aug. 1, 1996. (See Global Climate Change Digest, Prof. Pubs./General Interest, Aug. 1996.)

"Policy Statement: Atmospheric Ozone," 1247-1248. A summary (recently approved by the American Meteorological Society) of the current understanding of both stratospheric ozone depletion and tropospheric and urban ozone problems, and needed research.

"Scientific Background for AMS Policy Statement on Atmospheric Ozone," J. Hales, 1249-1253. (Contact G. Carmichael, Chair, Atmos. Chem. Committee, Amer. Meteor. Soc., 45 Beacon St., Boston MA 02108.) Discusses details behind the scientific understanding, stressing the coupling between chemistry and meteorology.
