UV impacts amphibians, according to two independent studies. Oregon researchers have found that UV harms the development of salamander embryos in the field. (See Blaustein article, Prof. Pubs./Ozone Depletion/Ultraviolet Radiation.) And EPA researchers in Duluth, Michigan, suspect that UV plays a role in frog deformities in Minnesota (Environ. Sci. & Technol., p. 12A, Jan. 1, 1998), contrary to an earlier finding implicating the chemistry of the water in which the frogs developed (ibid., p. 552A, Dec. 1997).

Item #d98mar129

Deforestation effects: A study of borehole temperatures in Canada shows a permanent rise in surface temperature of at least 1° C when forests were cleared for agriculture in the nineteenth century. The finding backs one of two competing theories used in climate models. (See New Scientist, p. 18, Feb. 14, 1998, and Lewis paper, Prof. Pubs./Gen. Interest & Policy, this Global Climate Change Digest issue—Mar. 1998.)

"Climatology Guru is Part Curmudgeon, Part Imp," W.K. Stevens,The New York Times, Mar. 17, 1998. An entertaining and informative profile of Lamont-Doherty Earth Observatory's Wallace Broecker.

Item #d98mar131

"If Climate Changes, It May Change Quickly," W.K. Stevens,The New York Times, pp. C1, C2, Jan. 27, 1998. Discusses the most recent evidence that Earth's climate can change quickly, and implications of this finding for climate in the near future. For instance, warming by greenhouse gases could be followed by a dramatic cold period.

Item #d98mar132

"Indonesia Opens the Door for Global Climate Studies," J. Mervis,Science, p. 1703, Dec. 5, 1997. The wave of forest fires sparked by El Niño has helped convince President Suharto to open his country to climate research, providing new opportunities for oceanographic and other studies.
