GENERAL INTEREST AND POLICY
"Are Global Cloud Albedo and Climate Controlled by Marine
Phytoplankton?" S.E. Schwartz (Environ. Chem. Div., Brookhaven Nat. Lab.,
Upton NY 11973), Nature, 336(6198), 441-445, Dec. 1, 1988.
Examines the hypothesized link between gaseous precursors of aerosol
sulfate, and global albedo and mean temperature. To test the effect of
dimethylsulfide emissions by marine plankton on climate, research was done to
determine the influence on climate of anthropogenic SO2 emissions, which are at
least twice as great as marine DMS. No influence was found in the present cloud
component or in the 100-year temperature records.
Discussions on "CO2 Reduction and Reforestation," Science,
242(4885), 1493-1494, Dec. 16, 1988.
Discusses difference between planting trees and reestablishment of forests
as a tool in climate control. Explains that forestation of marginal lands in the
tropics may require greater expenses and adjustment than planting of large areas
with woody plants. Finally, examines benefits of kelp farms.
"Prospects For Aircraft-Based Gas Exchange Measurements in Ecosystem
Studies," P.A. Matson (NASA-Ames Res. Ctr., Moffett Field CA 94035), R.C.
Harriss, Ecol., 69(5), 1318-1325, Oct. 1988.
Explains how aircraft sampling of the planetary boundary layer can determine
trace gas distributions and fluxes on regional scales, providing a link between
local and global-scale studies. Under stable atmospheric conditions, the
combination of lidar and in situ atmospheric sampling allows estimates of gas
exchange between the biosphere and atmosphere.
"Adjusting Water Resources Management to Climate Change," W.E.
Riebsame (Dept. Geog., Univ. Colorado, Boulder CO 80309), Clim. Change,
Discusses nature of climate impacts and adjustment in water supply and flood
management. Presents a case study in California's Sacramento Basin of
traditional approaches along with social constraints and climate extremes.
Specific mechanisms for adjusting water management systems are identified.
Suggests that excess capacity, the traditional mechanism for accommodating
climatic variability, may prove less feasible in the future.
"Atmospheric Trace Gas Studies in Antarctica," D.R. Cronn (Lab.
Atmos. Res., Washington State Univ., Pullman WA 99164), K.J. Schilling,
Rev. Geophys., 26(3), 497-518, Aug. 1988.
Trace gas studies have contributed to identification of circulation patterns
and mixing mechanisms. Stratospheric-tropospheric air exchange over Antarctica
occurs primarily as a result of general circulation patterns with subsidence
over the polar regions; stratospheric air injection in the vicinity of jet
streams and injection from tropopause folding upstream of troughs; and mountain
waves of sufficient magnitude to displace air parcels across the tropopause.
"The Significance of N2O in Nitrogen Oxide Emissions," J.
Jacobs, K.R.G. Hein, VGB Kraftwerkstechnik (West Germany), 68(8),
841-843, Aug. 1988. In German.
Describes influence on the greenhouse effect and the ozone layer by manmade
N2O emissions from power plants. Discusses the difficulties arising from
differing observational information, and possible production mechanisms.
"UNESCO's Man and the Biosphere Program," M.I. Dyer (Dept.
Entomol., Univ. Georgia, Athens GA), M.M. Holland, BioScience, 38(9),
635-641, Oct. 1988.
Evaluates progress of the international Man and the Biosphere Program (MAB),
that has focused on global environmental problems. Suggests that greater
effectiveness can be achieved if developing countries collaborate with
scientists and agencies in industrialized countries to understand local
environmental factors vital for sustainable development.
