• IMPACTS OF CLIMATE CHANGE: PHYSICAL AND CHEMICAL

Item #d94mar101

"An Assessment of Possible Climate Change in the Australian Region Based on an Intercomparison of General Circulation Modeling Results," P.H. Whetton (CSIRO Div. Atmos. Res., Pvt. Bag 1, Mordialloc, Vic., 3195 Australia), P.J. Rayner et al., J. Clim., 7(3), 441-463, Mar. 1994.

Studies involving the GISS, GFDL, UKMO and CSIRO models were intended to develop methods for verifying and using the results of GCMs for regional climate studies, as well as to estimate climatic impacts in the Australian region.

Item #d94mar102

"Evaluating Climate Change Impacts in Snowmelt Basins," P.H. Gleick (Pacific Inst. for Studies on Development, Environ. & Security, Oakland, Calif.), A. Rango, K. Cooley, Eos, 75(9), 107, Mar. 1, 1994.

Summary of an April 1993 workshop (Santa Fe, New Mexico) on hydrologic models for evaluating snowmelt impacts; gives research needs.

Item #d94mar103

"Effect of a Lowered Water Table on Nitrous Oxide Fluxes from Northern Peatlands," P.J. Martikainen (Dept. Environ. Microbiol., Natl. Publ. Health Inst., POB 95, FIN-70701 Kuopio, Fin.), H. Nykänen et al., Nature, 366(6450), 51-53, Nov. 4, 1993.

Compared N2O fluxes from virgin peatlands with those from nearby sites that were drained 30-50 years ago and thus represent the drier conditions that may result from greenhouse warming. Concluded that the peatlands will not exert a significant climate feedback from N2O emissions.

Item #d94mar104

"Random Walk Expectancies for Recent Global Climate, and in an Enhanced Greenhouse Warming," A.H. Gordon (Sch. Earth Sci., Flinders Univ. S. Australia, POB 2100, Adelaide SA 5001, Australia), J.A.T. Bye, Global & Planet. Change, 8, 181-188, 1993.

Suggests that the interannual variance and the ratio between its predictable and random proportions would change with enhanced greenhouse warming.

Item #d94mar105

"Effects of Climate Change on Water Resources in the Delaware River Basin," D.M. Wolock (USGS, 4821 Quail Crest Pl., Lawrence KS 66049), G.J. McCabe Jr. et al., Water Resour. Bull., 29(3), 475-486, June 1993.

The estuary's salt front would be sensitive to sea level rise, and levels in New York City reservoirs would be sensitive to changes in temperature and precipitation. However, the effects of natural variability would overwhelm long-term effects of temperature and precipitation trends.

Item #d94mar106

"Climatic Variability and Air Quality in the Great Plains of North America," S. LaDochy (Dept. Geog. & Urban Anal., Calif. State Univ., Los Angeles CA 90032), Clim. Bull., 26(3), 177-187, Dec. 1992.

Considers the potential for increased dust levels, including unhealthy levels of respirable particulates, due to a predicted warmer and drier climate.
