GENERAL INTEREST AND POLICY
Costs of Cutting Carbon Emissions: Results from Global Models,
Org. for Econ. Coop. & Devel. (OECD), 160 pp., July 1993,
$19/F80. In English and French. OECD Pubs., 2001 L St. NW, S-700,
Washington DC 20036 (202-785-6323); or OECD, 2 rue André-Pascal,
75775 Paris Cedex 16, France (tel: 33-1-45-24-82-00); or other
Compares on an equal basis estimates of the economic costs of
reducing CO2 emissions through carbon taxes, made by
six global energy-economic models.
and Predicting Atmospheric Chemical Change: An Imperative for the
U.S. Global Change Research Program, Nat. Res. Council, 31
pp., Aug. 1993. Request from Bd. on Atmos. Sci. & Clim. (HA
370), Nat. Res. Council, 2101 Constitution Ave. NW, Washington DC
The Global Tropospheric Chemistry Program (GTCP), the U.S.
Component of the International Global Atmospheric Chemistry
(IGAC) Program, and U.S. participation in the IGAC are seriously
underfunded and greatly weaken the U.S. Global Change Research
Program. The scientific issues concerning future levels of
atmospheric CO2, CH4, N2O, O3
and sulfate and carbonaceous aerosols are discussed, along with
the penalties of neglecting the necessary research.
Impacts of Global Climate Change on Natural Terrestrial
Ecosystems: A Scientific Perspective (BR-100835), Electric
Power Res. Inst., 20 pp., May 1993. Single copies free from EPRI
Distrib. Ctr., POB 23205, Pleasant Hill CA 94523 (510-934-4212).
A thorough overview, with several references, of current
scientific understanding of the problem and research being
conducted by EPRI and other organizations. There are large areas
of uncertainty, but the potential exists for three major types of
disruptions of terrestrial ecosystems: changes in the geographic
ranges of individual plant species and entire vegetation types;
loss of biodiversity; and positive or negative feedbacks to the
Natural Approach: Forestry and Global Climate Change, Offsets
Forum of the Alliance for Acid Rain Control and Energy Policy, 18
pp., July 1993. Contact the Alliance at 444 N. Capitol St, S.
602, Washington DC 20001 (202-624-5475).
The Forum members include state regulators, energy officials,
foresters and representatives of utilities and environmental
organizations. Promotes forestry as an effective way of
sequestering carbon to offset carbon emissions. Properly done,
forestry projects can result in a variety of environmental,
social and economic benefits. To be credited toward the
stabilization goal of the National Action Plan, individual
projects should be evaluated against a number of criteria
(described here) to ensure scientific validity, practicality,
ecological sustainability, and compatibility with local
Critical Issues Workshop, 33 pp., June 1993. Available from
Ctr. Global Environ. Studies, U.S. Dept. Energy, Oak Ridge Nat.
Lab., Oak Ridge TN 37831 (615-576-7785).
Report of a multidisciplinary, multi-agency workshop convened
by the U.S. Department of Energy (Cocoa Beach, Florida, Feb.
1993). Participants emphasized the need for a unified,
technically sound research program, and made specific
recommendations relating to four critical issues: (1) the
existing UV instruments and network are inadequate to identify
potential trends or validate radiative-transfer models; (2)
biological effects research must focus on key species,
process-level understanding, and identification of threshold UV-B
doses; (3) existing UV-B exposure systems have significant
deficiencies; (4) a critical need for integration of knowledge
and Global Change: Opportunities for Collaboration, Off.
Intl. Affairs, Nat. Res. Council., 200+ pp., 1992. National
Academy Press, 2101 Constitution Ave. NW, Washington DC 20418
(800-624-6242 or 202-334-3313).
Intended to facilitate scholarly collaboration that will
increase understanding of China's impact on global change and the
impact of global change on China. Includes an overview on
relevant institutions, Chinese participation in international
research programs, summaries of research on atmospheric and other
topics, and detailed supplementary information of research
Warming: Failed Forecasts and Politicized Science (Occas.
Paper 125), P. Michaels (Environ. Studies, Univ. Virginia), 22
pp., June 1993. Available from Ctr. Study Amer. Business, Campus
Box 1208, Washington Univ., St. Louis MO 63130.
Comparison of temperature records with climate model
simulations for the same period demonstrates a remarkable
disparity between forecasts of disastrous climate change in the
future and the atmosphere's response so far. The extreme
politicization of this topic can only be remedied with further
