Item #d95feb140

"Pumping Iron in the Pacific," K. Van Scoy, K. Coale, New Scientist, 32-35, Dec. 3. Full-length article by two participants of the recent experiment exploring the uptake of atmospheric CO₂ by ocean phytoplankton "fertilized" with iron. They describe its findings, and the new questions it raises that are leading to another experiment in May.

Item #d95feb141

"How Many Species Do We Need?" J. Cherfas, ibid., 36-40, Aug. 6, 1994.

Describes the Ecotron at the Imperial College of London, a controlled, closed ecosystem facility considered halfway between the laboratory and the field. Researchers are studying effects of doubling CO₂ and raising temperature by 2·C.

Item #d95feb142

"Ozone Alert," E Magazine, 5(4), 22-24, July-Aug. 1994 (Earth Action Network, POB 699, Mt. Morris IL 61054).

A four-year study at Oregon State University provides strong evidence that the thinning of the ozone shield and increase in UV radiation are causing the decline of amphibian populations.

Item #d95feb143

"Understanding the Global Carbon Cycle," J. Douglas, EPRI Journal, 34-41, July-Aug. 1994.

An EPRI model (GLOCO) simulates many processes driving the carbon cycle. A more complex computer program that can model the global carbon cycle with reference to specific geographic patterns is being developed.

Item #d95feb144

"Not Warming But Cooling," F. Pearce, New Scientist, 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 trends. (A letter to the editor in the Sep. 3 issue (p. 48) questions why the Pearce article did not mention the effects of aviation on the atmosphere.)

Item #d95feb145

"EOS Evolving to Meet Budget Restraints," H. Hough, Earth Observation Magazine, 20-23, July 1994.

Describes NASA's Earth Observing System (EOS) and its information storage database (EOSDIS). The EOS project must continue to evolve if it is to survive political budget battles. Also contains a calendar and summary of NASA's planned "Mission to Planet Earth" space-based observational missions through the end of the century.
