Hearings on U.S.
global change research were held in both the Senate and the House on March
30. John Gibbons, the President's science advisor, emphasized the need to expand
the research beyond its current focus on hard science by including issues such
as the impacts of change and how to adapt to them. Another theme, voiced by
atmospheric scientist James Anderson, was the need for a better balance between
large, expensive projects and smaller, more flexible ones aimed at answering
specific mechanistic questions, such as why ozone is thinning over the Northern
Hemisphere. (See Chem. Eng. News, p. 8, Apr. 5 1993; Eos, p.
162, Apr. 6 1993; Environ. Rptr. Curr. Devel., p. 3088, Apr. 2 1993.)
Special Section: "Evolution
of Atmospheres," Science, Feb. 12. Contains the following lengthy
perspective pieces, in addition to the four technical reviews listed in Professional Publications / General Interest - Science":
- "Is the Geological Past a Key to the (Near) Future?" E. Culotta,
pp. 906-908. To develop climate simulations that can be trusted, modelers are
turning to evidence from the past, turning paleoclimatology into (in the words
of one researcher) "an applied science."
- "Searching for Clues to Ancient Carbon Dioxide," T. Appenzeller,
908-909. Earth scientists are now finding ingenious ways of reading the record
of past carbon dioxide balances in sedimentary rock and deep-sea sediment. The
techniques are so new that their interpretation remains an uncertain art.
- "Earth Scientists Look NASA's Gift Horse in the Mouth," G. Taubes,
912-914. From the start of the Earth Observing Program, launched in 1989,
critics argued that the grandiose project would gather huge amounts of
undigestible data and would siphon away financial resources from other--perhaps
more worthy--efforts at climate monitoring. Although NASA has modified the
program in response to critical reviews and budget cuts, the controversy seems
to be growing.
"Ecologists Put Some
Life into Models of a Changing World," Y. Baskin, Science, pp.
1694-1696, Mar. 19, 1993.
This lengthy survey of efforts to link ecological models of Earth vegetation
with general circulation models of the atmosphere and ocean is based on a
January workshop for biological, physical and social scientists from 50
countries, sponsored by the IGBP in Ensenada, Mexico. Participants were
impressed by the progress made in ecological models in the last few years.
Summarizes results of one model showing that the fertilization effect of rising
CO2 would first help, then hinder, efforts to slow the buildup of greenhouse
"Government to Fund £1
Million Study on Environmental Effects of UV-B Radiation," Intl.
Environ. Rptr., p. 302, Apr. 21. The four-year program, to be carried out at
seven universities and research institutes across Britain, will examine
mechanisms of effects on crops and ecosystems through laboratory and field
experiments. Species will be bred for increased tolerance to UV-B.
"Can Basic Science
Ever Find a Good Home in Biosphere 2?" T. Watson, Science, Mar. 19.
Biologist John Corliss, formerly with NASA, has a challenging new job: bringing
scientific respectability to the glass-enclosed ecosystem in the Arizona desert
that is an odd hybrid of commercial tourist attraction, New Age venture, and
research project. (See related BioScience paper in Prof. Pubs./Gen.
Impact of Population Growth," R. Naylor, P. Matson, Eos, pp.
178-179, Apr. 13. An account of the August 1992 Aspen Global Change Institute,
Food, Conservation and Global Environmental
Change: Is Compromise Possible? Researchers from a wide variety of
disciplines explored multidisciplinary approaches to decision making on the
"Global Science at
the Coastal Interface: Fluxes, Forcing Factors and Feedbacks," P.
Williamson, Ambio, p. 59, Feb. Describes a new IGBP core project
established to determine the role of coastal systems in global change. The
science plan is now available from Patrick Holligan, Plymouth Marine Lab.,
Prospect Pl., Plymouth PL1 3DH, UK.
The Climate and Global
Change Program of the National Atmospheric and Oceanic Administration is
accepting proposals for fiscal year 1994 on a wide range of topics. Letters
of intent are due June 4; proposals Aug. 8. Contact NOAA/Off. Global Progs.,
1100 Wayne Ave., S. 1225, Silver Spring MD 20910 (301-427-2089).
The U.S. Department of
Energy is soliciting proposals to support the experimental and theoretical study
of radiation and clouds in conjunction with its Atmospheric Radiation
Measurement Program. Contact Off. Energy Res., ER-74, U.S. DOE, Washington DC
