RETROSPECTIVE: 1987 PAPERS
"Global Climate Change: Toward a Greenhouse Policy," J.T.
Mathews (World Resour. Inst., 1735 New York Ave. NW, Washington DC 20006), Issues
Sci. & Technol., 3(3), 57-68, Spr. 1987.
Gives a brief review of scientific evidence of likely greenhouse warming
followed by an extensive discussion of policy options. Concludes that the costs
of waiting for scientific certainty are too great; instead the U.S. should act
now to avert unacceptably large warming. Suggestions include increasing energy
efficiency, reducing the use of carbon-rich fuels, phasing out
chlorofluorocarbons, beginning international discussions on the greenhouse
effect and long-range energy studies.
"An Environmental Agenda for World Business," J.G. Speth
(address immed. above), Across the Board, 21(6), 21-26,
Discusses the emergence of a new spirit of cooperation that has begun to
replace the once acrimonious relations between business and environmental
groups. Multinational corporations have excellent economic and political reasons
to work with environmental groups; they depend on resources threatened by major
problems such as the greenhouse effect, forest depletion, misuse of energy
resources. A consensus may be emerging on the most urgent global
"Mankind's Impact on Climate: The Evolution of an Awareness,"
W.W. Kellogg (NCAR, POB 3000, Boulder CO 80307), Climatic Change, 10(2),
113-136, Apr. 1987.
An extended commentary on the growth of an awareness of the crucial role of
infrared-absorbing gases, on the research advances in understanding the various
components of the climate system, especially through the use of numerical
models, and on the questions posed by the prospect of global warming. There is
already a sharp debate between the activists, who would take action worldwide to
counter climate change, and those who would simply wait and see what happens and
perhaps take what local measures are necessary.
"U.S. Report to the International Union of Geodesy and Geophysics,"
Rev. of Geophys., 25, Mar., Apr., July 1987.
A collection of papers constituting the quadrennial report to the IUGG,
which reviews and updates research advances during 1983-1986 in physical and
chemical oceanography, atmospheric science, aeronomy (including stratospheric
chemistry), and solid earth geophysics. Papers of most direct relevance to
global climate change follow; most include extensive reference lists.

Special issue: Tellus, 39B(1-2), Feb.-Apr., 1987.
Most of the 21 papers in this issue were presented at the International
Conference on Atmospheric Carbon Dioxide, Its Sources, Sinks and Global
Transport, Sep. 1985, Kandersteg, Switzerland. Those of most direct interest
"The Flux of Carbon from Terrestrial Ecosystems to the Atmosphere in
1980 Due to Changes in Land Use: Geographic Distribution of the Global Flux,"
R.A. Houghton (Woods Hole Res. Ctr., Woods Hole MA 02543), R.D. Boone et al.,
The net release of C to the atmosphere in 1980 from changes in land use is
estimated to be 1.0-2.6 x 1015 g, mostly from deforestation in the tropics. The
global net release is inconsistent with results of geochemical models of the C
cycle; possible explanations include net accumulation of C in undisturbed
ecosystems as a result of CO2 fertilization or climate changes. Even if the C
budget were to appear balanced, current knowledge is insufficient to predict
whether terrestrial ecosystems will act as a positive or negative feedback on
the anticipated global warming.
"Biospheric CO2 Emissions During the Past 200 Years Reconstructed by
Deconvolution of Ice Core Data," U. Siegenthaler (Phys. Inst., Univ. Bern,
CH-3012 Bern, Switz.), H. Oeschger, ibid., 140-154.
Measurements using air trapped in old polar ice have revealed that the
pre-industrial atmosphere contained 280 ppm of CO2 and that delta 13C of
atmospheric CO2 decreased by about 1.1% until 1980. These results indicate
considerable amounts of non-fossil CO2 must have already been emitted into the
atmosphere in the 19th century. Estimates of emission rates using box models
indicate net non-fossil production rate was roughly constant in the 19th and
early 20th centuries. Smaller values obtained for the past 30 years may be due
to other sinks, such as stimulation of plant activity by enhanced CO2
"Modelling Stimulation of Plants and Ecosystem Response to Present
Levels of Excess Atmospheric CO2," G. H. Kohlmaier (Inst. Phys. Chem.,
Niederurseler Hang, Univ. Frankfurt, D-6000 Frankfurt am Main 50, FRG), H. Br?hl
et al., ibid., 155-170.
Reviews available experimental data and field observations to understand
implications of the observed increase in the amplitude of the CO2 seasonal
cycle. Results suggest an experimental stimulation factor for net primary
production of between 0.25 and 0.50. Discusses global, 3-compartment models for
living biota, litter and humus, and uses them to estimate the amount of C
sequestered annually in the biota pool.
"A Look at 1983 CO2 Emissions from Fossil Fuels (with Preliminary
Data for 1984)," R.M. Rotty (Mech. Eng., Univ. New Orleans, New Orleans LA
70148), ibid., 203-208.
Global emissions of CO2 from fossil fuels continued to decline slightly in
1983 for the fourth consecutive year as a result of reduced use of liquid fuels.
But preliminary data for 1984 strongly suggest that the decline is over;
emissions were greater than previous years except 1979. Growth in fossil fuel
use and resulting emissions have continued in the developing world in contrast
to the decline observed in developed countries of the western world; this could
have important implications for future global emissions.
"The 1982-1983 El Ni?o: A 6 Billion Ton CO2 Release," A.
Guadry (Centre National de la Recherche Scientifique, Av. de la Terrasse, BP 1,
91190 Gif/Yvette, France), P. Monfray et al., ibid., 209-213.
The atmospheric CO2 concentration at Amsterdam Island showed important
variations of the increase rate during this event. The curve shifted upward by 1
ppm, corresponding to a supplementary input of about 6 billion tons of CO2.
