Item #d93may80

"Under the Ozone Hole," S. Vogel, Earth, 30-35, Jan. 1993.

Discusses research on the ecosystem effects of increased ultraviolet radiation resulting from stratospheric ozone depletion.

Item #d93may81

"Coral Bleaching," B.E. Brown, J.C. Ogden, Scientific American, 64-70, Jan. 1993.

Extensive areas of subtly colored tropical coral reefs have turned white or even died, but the global extent of coral reef damage has not yet been assessed. The bleaching, which may be a sign of stress such as that usually exhibited when coral experiences high water temperatures, raises the question of global warming as a factor.

Item #d93may82

Two items from New Scientist, Dec. 19/26, 1992:

"A Plague on Global Warming," F. Pearce, 12-13. An unpublished report of the British Public Health Laboratory Service warns of malaria and even the plague in Europe if warming occurs. Health problems elsewhere and impacts on agricultural pests are also discussed.

"Mirage of the Shifting Sands," F. Pearce, 38-42. Challenges methods of detecting desertification and even the existence of any trend in desertification, the justification for extensive expenditures over the past two decades, and the basis of a proposed U.N. convention.

Item #d93may83

"Aircraft Emissions Threaten the Atmosphere: A Test for the Precautionary Principle," S. Cave, Our Planet, Vol. 4, No. 5, 20-22, 1992 (U.N. Environ. Prog., POB 30552, Nairobi, Kenya).

Research underway shows that increasing jet travel may alter climate and stratospheric ozone through its emissions of nitrogen oxides and water vapor.
