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 3, NUMBER 8, AUGUST 1990
"Warming Shouldn't Wither U.S. Farming," R. Monastersky, Science
News, p. 308, May 19, 1990. The first comprehensive study on the topic finds
that warming will not have major catastrophic effects on the welfare of
producers or consumers of agricultural products. (See Adams article, PROF.
PUBS./GEN. INTEREST, this Global Climate Change Digest issue--Aug.
"Methane May Amplify Climate Change," J. Gribbin, New
Scientist, p. 31, June 2, 1990. Analysis of bubbles of air in the Antarctic
Vostok ice core indicate that changes in methane levels in the past correlated
with changes in climate. (See Chappellaz article, PROF. PUBS./GEN. INTEREST,
this Global Climate Change Digest issue--Aug. 1990).)
"That Thinning Feeling," Chem. & Industry, p. 275,
May 7, 1990. Discusses the considerable uncertainties associated with
measurements showing increasing UV-B radiation reported in Europe. (See
Blumthaler article, PROF. PUBS./TREND ANALYSIS & PREDICTION, Global
Climate Change Digest, June 1990.)
"CO2 Jumps before Ice Sheets Slump," R. Monastersky, Science
News, p. 382, June 16, 1990. Results from the Vostok ice core, presented by
a University of Rhode Island group at the spring AGU meeting, provide new
evidence that a rise in CO2 helped melt ice sheets at the end of an ice age
about 130,000 years ago. (See also Science, p. 1607, June 29, 1990.)
"Antarctic Ice Potentially Unstable," Science News, p.
285, May 5, 1990. Erratic motion observed recently in an Ant-arctic glacier
indicates a serious lack of understanding of stability of the Antarctic ice
sheet. A workshop report issued in April calls for more research to evaluate the
likelihood that the ice sheet could collapse into the ocean in the next few
centuries, which could cause a six-meter rise in sea level.
