climate change: A study finding a shift in the range of a certain butterfly,
reported in the Aug. 29 issue of Nature, claims to present "the
clearest indication to date that global warming is already influencing species'
distributions." (See Parmesan article in Prof. Pubs./Of Gen. Interest, this
GLOBAL CLIMATE CHANGE DIGEST issue--Oct.-Nov. 1996; Science News,
p. 135, Aug. 31; New Scientist, p. 9, Aug. 31; The New York Times,
p. C4, Sep. 3.) In the Times article, the author of the study also
states "I cannot say that climate warming has caused the shift; what I can
say is that it is exactly what is predicted from global warming scenarios...."
The Sep. 16 issue of World Climate Report, a biweekly research review
that takes a skeptical attitude toward climate change, highlighted this
qualification. It also points out that the study did not attempt to determine
the temperature history in the study region (western North America), and
presents temperature data showing no trend there over the past few decades.
(International Geosphere-Biosphere Program): The latest two issues OF its Global
Change Newsletter have special themes of wider interest.
No. 27 (Sep. 1996) is a special 32-page issue on "Data and Information"the
development of quality data sets for use in IGBP projects and the scientific
community at large.
No. 26 (June 1996) reports on the first IGBP Congress in its 10-year
history, held in April 1996 in Bad Münstereifel, Germany. It marked the
entry of the IGBP into a new phase in which program integration and synthesis of
results are becoming a reality. One article discusses ways of communicating the
results of IGBP research to the world at large in the year 2000, using the mass
Trees siphon CO2:
Researchers from Duke University (Durham, N.C.) are finding that trees may move
CO2 from the atmosphere to soil where it can be dissolved and stored
for centuries in ground water. Preliminary results presented at the annual
meeting of the Ecological Society of America (Aug. 14, Providence, R.I.) imply
that the rate of growth of CO2 might be slower than indicated by the
growth of emissions. (See Intl. Environ. Rptr., p. 758, Aug. 21, 1996).
