"Fighting Fire with Fire," L. O'Hanlon, New Scientist, 28-33, July 15, 1995.

Wildfires are becoming hotter, more devastating and more frequent because controlled burning of undergrowth has decreased, allowing for infrequent and unpredictable firestorms. There has been a change from burning to reduce surface fuels to burning for land clearing. The former has a negligible net impact on atmospheric CO₂ because the vegetation regrows. The same is not true of the latter, which permanently changes land use.

Item #d95aug54

"The Puzzle of Declining Amphibian Populations," A.R. Blaustein, D.B. Wake, Scientific American, 52-57, Apr. 1995.

Many species of amphibians are mysteriously dwindling or disappearing. The destruction of their natural habitats, pollution, disease, changes in the ozone layer, and even taste in food may be at the bottom of this development.

Item #d95aug55

"Of Whales and Ocean Warming," J. Kaiser, Science News, pp. 350-351, June 3, 1995. (See Global Climate Change Digest News, July 1995).

Item #d95aug56

" Drying Out the Tropics," D. Rind, New Scientist, pp. 36-40, May 6, 1995.

A climatologist gives a detailed summary of recent evidence suggesting that, contrary to conventional wisdom, global warming could substantially affect the tropical climate. It is vital to track tropical temperatures and watch how they change.

Item #d95aug57

"Will Plants Profit from High CO₂?" E. Culotta, Science, 654-656, May 5, 1995. Summarizes recent experiments, which indicate that elevated CO₂ may help crops grow better, but the overall effect on plants in natural ecosystems remains unknown. Elevated CO₂ will alter the growth of green plants whether or not it warms the globe.

Item #d95aug58

"El Niño Goes Critical," B. Wuethrich, New Scientist, pp. 32-35, Feb. 4, 1995.

A lengthy examination of the recent increase in frequency of El Niño events in the equatorial Pacific and associated alterations in world weather patterns. Looks at whether there is a connection to greenhouse warming.
