Archives of the
Global Climate Change Digest
A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999
FROM VOLUME 6, NUMBER 10, OCTOBER 1993
EARTH SYSTEM SCIENCE
three articles titled "The Climate Conundrum" in New
"Can Algae Cool the Planet?" N. Fell, P. Liss,
34-38, Aug. 21, 1993. Scientists have only recently appreciated
the crucial role of the sulfur cycle in the climate system, as it
links oceanic phytoplankton growth to cloud formation through the
gas dimethylsulfide. Under investigation is whether phytoplankton
could be deliberately fertilized with iron to spur oceanic uptake
"Chill Warnings from Greenland," R.H. Nielsen,
29-33, Aug. 29. Recent ice core results show that sudden swings
in the world climate were the rule over many thousands of years.
"Waiting for the Polar Meltdown," M. Maslin, 36-41,
Sep. 4. The author is part of a scientific team investigating
repeated surges in iceberg activity in the Earth's past known as
the Heinrich events. Speculates on how our current knowledge
applies to ice sheet breakup in a warmed climate.
Fuel for Global Warming?" D. McInnes, Earth, 20-23,
Nov. 1993. The recent finding that Arctic tundra is releasing CO2
leads researchers to suspect that the carbon balance is shifting
as a result of global warming, and could reinforce warming in the
"Past Climates Hold Clues to Global Warming," E.
Culotta, Earth, 20-22, Sep. 1993.
The study of paleoanalogs, popular with Russian
climatologists, is based on the assumption that we can learn
about future climate by examining periods in the Earth's
climatological history when CO2 was high. Most western
scientists prefer to use computer models instead.
"Monitoring Global Temperature from Space," J.R.
Christy, R.W. Spencer, Storm, 18-23, Aug. 1993. (Premier
issue of this new publication on world weather: Ulick Publishing,
POB 579, Batavia IL 60510; 708-406-8330.
Two U.S. researchers explain how data from the Microwave
Sounding Units (MSUs) on board several satellites will help
detect temperature variability and trends.
"Researchers Lack Data on Trends in UV Radiation at Earth's
Surface," P.S. Zurer, Chem. Eng. News, 35-37, July
26, 1993. (See Research News, Global Climate Change Digest,
p. 15, Sep 1993.)
"Chemist at the Ends of the Earth," R. Stevenson, Chem.
in Britain, 551-552, July 1993. A profile of stratospheric
ozone researcher Susan Solomon.
"Ocean-in-a-Machine Starts Looking Like the Real
Thing," R.A. Kerr, Science, 32-33, Apr. 2, 1993.
The supercomputer, fine-mesh ocean circulation model developed
by Albert Semtner and Robert Chervin is impressing other
oceanographers. Its representation of the Indian Ocean
"conveyor belt" flow has implications for the stability
of the conveyor during climate change.
"Underground Records of Changing Climate," H.N.
Pollack, D.S. Chapman, Sci. American, 44-50, June 1993.
Boreholes drilled into continental rock can recover fossil
temperatures that reveal the climate of the past, but the results
require careful interpretation.
Issue: "Biological Oceanography," Oceanus,
Fall 1992. Includes the following:
"An Introduction to Biological Oceanography," D.A.
"What Limits Phytoplankton Growth?" S.W. Chisholm,
36-46. Includes discussion of iron fertilization.
"GLOBEC: Global Ocean Ecosystems Dynamics," M.
Huntley, 94-99. Describes this interagency component of the U.S.
Global Change Research Program.
