Global Climate Change Digest
A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999
FROM VOLUME 5, NUMBER 1, JANUARY 1992
CO2 Emissions Drop: Researchers at the Worldwatch Institute find
that world emissions of CO2 have decreased in the last two years, and expect the
decline to continue into 1992. Factors responsible include energy efficiency
measures in developing countries, the U.S. recession, and disruption of
industrial activity in eastern Europe and the Soviet Union. Emissions for 1990
are documented in Worldwatch's State of the World 1992 (see Reports,
this GLOBAL CLIMATE CHANGE DIGEST issue--Jan. 1992).
Canadian Reports: Environment Canada released two major reports in
December, one a background survey of atmospheric change and implications for
Canada, the other a summary of current understanding of impacts of climate
change on Canada. (See Reports, this GLOBAL CLIMATE CHANGE DIGEST issue--Jan.
Costs of Controlling CO2: A new study prepared for the American
Petroleum Institute compares several recent energy analyses and concludes that
the costs of reducing CO2 emissions are high, while economic benefits are
uncertain, distant and small. (See Reports, this GLOBAL CLIMATE CHANGE
DIGEST issue--Jan. 1992.) An article in Intl. Environ. Rptr. (pp.
688-689, Dec. 18, 1991) includes comments on the study and the models examined,
by Alan Miller of the University of Maryland Center for Global Climate Change.
Singer-Winston Survey: S. Fred Singer, former director of the
National Weather Satellite Service, and Jay S. Winston, former director of the
Weather Service's Climate Analysis Center, recently arranged a survey of
scientists involved with the IPCC Scientific Assessment of Climate Change,
because some scientific contributors to the report disagreed with the
conclusions of its widely distributed nontechnical summary. Singer and Winston
conclude from the survey results that the summary greatly exaggerates the degree
of consensus among scientists concerning the likelihood and unfavorable
consequences of climate change. (See Reports, this GLOBAL CLIMATE CHANGE
DIGEST issue--Jan. 1992.)
VOC Agreement: Nineteen European nations, the U.S. and Canada have
agreed to control emissions of volatile organic compounds (VOCs), precursors to
regional ozone and smog which also contribute to rising levels of tropospheric
ozone. The treaty is the third under the U.N. Economic Commission for Europe,
following those on oxides of sulfur and nitrogen. See New Scientist, p.
15, Nov. 30, 1991; Intl. Environ. Rptr., pp. 618-619, Nov. 20.
New Publication: Energy, Economics and Climate Change began
monthly publication in October 1991, with detailed reviews and interpretations
of the latest national and international policy responses to climate change, and
implications for the energy industry. The first issue (16 pp.) includes articles
on revisions to the Manne-Richels model, the Stanford University Energy Modeling
Forum, International Energy Agency activities, and estimating costs of
reforestation as a way to offset CO2 emissions. Contact Cutter Info. Corp., 37
Broadway, Arlington MA 02174 (617-648-8700); $547 ($647 outside N. America).
"UN Fears Pollution Curbs Could Raise Temperatures," F. Pearce,
New Scientist, p. 5, Jan. 4, 1992. A United Nations IPCC report to be
published in February concludes that acid pollution in the form of sulfate
particles is probably shielding Europe and North America from global warming.
The IPCC climate modeling group agreed in November to include this finding in
its new report, to be approved at a meeting in Beijing in January.
