declassified: The U.S. Navy is starting to release physical data about the
oceans gathered during the cold war, which scientists see as a bonanza for
understanding global warming and other types of environmental change.
Measurements include ice depth, ocean depth, sea-surface height, salinity, and
water temperature. A group of scientists from academia and industry,
known as Medea (from Measurements of Earth), is advising the nation's
intelligence agencies on how secret data can be used to study the environment.
Their recent report is available on request (tel: 703 883 5265; fax: 703 883
6190). See The New York Times, pp. C1, C12, Nov. 28, 1995.
global models, with dynamic biogeochemical ecosystem components that
interact realistically with the physical ocean-climate-land system, were the
focus of a September conference convened in Germany by the IGBP. Presentations
suggest that the ability to predict the broad characteristics of regional
climate on seasonal to interannual timescales could be realized within the next
ten years. (See Nature, p. 12, Nov. 2, 1995.)
Plant moisture loss
under global warming depends on the combined effects of temperature and
rising CO2 on leaf transpiration. Calculations by John Lockwood of
the University of Leeds show that there has probably been a net reduction in
evaporation from plants of 2-5% in the second half of this century. (See
Lockwood paper in Prof. Pubs./Impacts/Ecosystems, this Digest
issue--Dec. 1995.) Some other interesting results are discussed by J. Gribbin in
New Scientist, p. 21, Sep. 30, 1995.
