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