GENERAL INTEREST AND POLICY
1992 IPCC Supplement, 70 pp., Feb. 1992. IPCC Secretariat, World
Meteor. Org., Case Postale 2300, 1211 Geneva 2, Switz.
(See News, this GLOBAL CLIMATE CHANGE DIGEST issue--May 1992.)
Findings since 1990 either confirm or do not justify alteration of the major
conclusions of the first IPCC Assessment. Among the seventeen significant new
developments are the following: decreased radiative forcing from stratospheric
ozone depletion roughly balances increased forcing from CFCs; the cooling effect
of sulfate aerosol resulting from sulfur emissions may have offset a significant
part of the greenhouse warming of the past several decades; better understanding
of the usefulness and uncertainty of global warming potentials of greenhouse
gases has been achieved; scenarios for predictions of warming and its impacts
have been improved; transient (rather than steady-state) global model
simulations have been successfully used to confirm predicted rates of warming;
observations show that warming over the northern midlatitude continents has
occurred mainly at night.
The finding on sulfur emissions warrants a revision of the estimated rate of
warming of 0.3° C per decade for Scenario A of the 1990 assessment: the
rate is likely to be reduced, especially in the Northern Hemisphere, by an
amount dependent on the future magnitude and regional distribution of sulfur
Global Warming: The Economic Stakes, W.R. Cline, 128 pp., Apr.
1992, $12. Inst. for Intl. Econ., 11 Dupont Circ. NW, Washington DC 20036
A summary of a forthcoming book-length analysis, The Economics of Global
Warming, which goes beyond estimates of the costs of abatement of greenhouse
gases to examine the benefits of avoiding future warming, over a much longer
time frame than usually examined. The damage to the U.S. economy over the next
300 years is likely to total 6% of gross national product, and could reach 20%
under an alternative, high-damage scenario. Advocates an aggressive global
initiative to limit the greenhouse effect, including in a first phase a "best
efforts" (but not legally binding) commitment to limit carbon emissions by
the year 2000 to their 1990 levels, combined with increasing carbon taxes. If
the scientific outlook warrants, a stronger regime would begin after the year

Hall, Rm. 300, State Univ. N.Y., Albany NY 12222 (518-442-3850).
The following three publications are available at no charge from Climate
Network Europe, 44 rue du Taciturne, 1040 Brussels, Belgium (tel: 32 2 231
International NGO Directory, 102 pp., Feb. 1992. A directory of the
Climate Action Network, a coalition of more than 100 nongovernmental
organizations, who share a concern for the greenhouse effect and wish to
cooperate in developing and implementing short- and long-term strategies.
Everything You ever Wanted to Know about Climate Change: An Annotated
Bibliography of Key Publications on Climate Change, 84 pp., June 1991.
Energy, transportation, agriculture and policy specialists chose and reviewed
the ten most significant publications on climate change in their fields.
Intended to raise public awareness and understanding of the issues.
Global Warming and the EC Budget: Recommendations to the European
Parliament in the Debates on the 1992 Budget, 64 pp., May 1991. NGOs from
the Climate Action Network drew up alternative options for the EC energy budget,
and have made recommendations in other important sectors of EC policy relating
to CO2 strategy.
Uncertainties with Respect to Biogenic Emissions of Methane and
Nitrous Oxide (ENR92-03), K.M. Lemon, L.A. Katz, N.J. Rosenberg, 1992, $5.
Publications, Resources for the Future, 1616 P St. NW, Washington DC 20036
A discussion paper estimating the amounts of CH4 and N2O from various
biogenic sources. Suggests ways to reduce uncertainties associated with these
estimates and options for curtailing the emissions themselves. Concludes that
the burden for curtailing the greenhouse effect lies with producers of CO2.
Life Support: Conserving Biological Diversity (Paper 108), J.C.
Ryan, 62 pp., Apr. 1992, $5. Order from Worldwatch Inst., 1776 Mass. Ave. NW,
Washington DC 20036 (202-452-1999).
Details an unprecedented, world-wide biological collapse that is resulting
in a massive wave of extinctions, concluding that climate change from CO2
emissions is likely to accelerate this. Rapidly rising temperatures will
overwhelm the ability of many species and ecosystems to adapt. Discusses
protection of ecosystems, conservation beyond parks, living with diversity,
greenhouse biology and ecological integrity.
World Resources 1992-1993, World Resour. Inst., 384 pp., Feb.
1992, $19.95. Available in paperback from WRI Publications, POB 4852, Hampden

Published in collaboration with the U.N. Environment Programme and U.N.
Development Programme, this report serves as a desk reference for essential data
on natural resources and the environment, including energy use and tropical
deforestation. Among the highlights are the first global estimates of land
degradation, which since World War II has damaged soils in an area larger than
that of India and China combined. A special report looks at global development
patterns and shows that despite a surge of world economic growth and notable
social progress by many developing countries, the economic gap between rich and
poor countries has widened.

from Carbon Dioxide Info. Anal. Ctr., Oak Ridge Nat. Lab., Oak Ridge TN 37831.
This second issue in the series expands the coverage of sites recording
atmospheric concentrations of CO2 and CH4 and updates records previously
reported. New data include: historical data from ice cores for N2O; modern
records for atmospheric concentrations of CFC-11, CFC-12 and N2O; regional CO2
emission estimates; global and hemispheric temperature-anomaly records from
Recommendations for Creation of the Global Change Research
Information Office [GCRIO], Ad Hoc Task Group on a Global Change Research
Information Office, 70 pp., Nov. 1991. Keith W. Russell (Chair, GCRIO Task
Group), Nat. Agric. Lib., USDA, 10301 Baltimore Blvd., Beltsville MD 20705
These are among the recommendations: (1) establish and staff the GCRIO as
soon as possible as a medium-sized operation that initially would serve as a "front
office" for receipt of requests for information from foreign citizens and
institutions; (2) maintain close ties with other government agencies and private
organizations to assure high levels of mutual awareness of resources, services
and products; (3) assess users' needs regularly; (4) expand the target audience
to include U.S. citizens and organizations.
