FROM VOLUME 7, NUMBER 7, JULY 1994
NEWS... RESEARCH NEWS
impacts: Experiments reported in the July 1 issue of Science
highlight the shortcomings of current UV research, and may force
marine biologists to rethink the way they study the effects of
UV-B, as discussed in a commentary on p. 30 of that issue, and in Science
News, p. 4, July 2. (See Bothwell article, Prof. Pubs./Gen.
repair scheme: Physics professor Albert Wong has published a
paper describing a scheme for removing ozone-destroying chlorine
from the atmosphere with negative charges. (See paper in Prof.
Pubs./Stratospheric Ozone.) Although covered by the national news
media, the idea is being criticized by other scientists. (See Chem.
Eng. News, p. 36, May 23; New Scientist, p. 9, May 21; Science,
pp. 1401-1402, June 3.)
drought history: Researchers have found evidence of
century-long droughts in California during medieval times. (See
papers from Nature, June 16, in Prof. Pubs./Gen.
Interest/Climate Change Science.) The finding raises concern over
what conditions could induce such an extreme drought in the
future. (See New Scientist, p. 10, June 25; feature in Global
Environ. Change Rep., pp. 1-3, June 24; The New York Times,
pp. C1, C9, July 19.)
program document: Objectives and scientific issues of the
Stratospheric Processes and Their Role in Climate (SPARC) project
of the World Climate Research Program have recently been
published. This document and twice-yearly newsletters are
available from the SPARC Office in France. (See Reports.)
response proposals: The Southern Global Change Program of the
U.S. Forest Service is requesting proposals by Oct. 15 for the
development and application of a regional forest ecosystem model,
which would integrate knowledge of how southern (U.S.) forest
ecosystems respond to changes in their environment. Contact the
program office at the USDA Southeast Forest Exper. Sta., 1509
Varsity Dr., Raleigh NC 27606 (919-515-3311).
Warming But Cooling," F. Pearce, New Scientist, pp.
37-41, July 9. A feature article summarizing discussion at Dahlem
Workshop on Aerosol Forcing of Climate (Berlin, Germany, Apr.
1994), which stressed the different geographical scales of
greenhouse warming and cooling by aerosols, and possible future
Eased About CFC Substitutes' Breakdown," Chem. Eng. News.
pp. 7-8, July 4. U.S. Geological Survey scientists have published
evidence that eases a nagging worry about the environmental
impacts of a breakdown product of common CFC substitutes. (See
Visscher paper in Prof. Pubs./Gen. Interest/CFC Replacements.)
following appear in the June issue of Global Change Newsletter,
available from the IGBP Secretariat, Royal Swedish Acad. Sci.,
Box 50005, S-104 05 Stockholm, Sweden:
"Where Are We and Where Should We Go?" pp. 10-11.
Gives the terms of reference and plan for an external evaluation
of the operational phase of the IGBP, which began in 1990. The
review should be completed by fall of 1995.
"Ecological Complexity and Ecosystem Function: The
Effects of Global Change," O.E. Sala, pp. 1-2. Discusses the
new focus of the Global Change and Terrestrial Ecosystems (GCTE)
Core Project of IGBP.
"Biosphere-Atmosphere Field Experiment in Amazonia,"
C. Nobre, pp. 3-4. Describes preparations for a large-scale land
surface experiment in Amazonia slated for 1997-1999.
