Item #d88jul51

"Estimated Annual Regime of Energy-Balance Components, Evapotranspiration and Soil Moisture for a Drainage Basin in the Case of a CO2 Doubling," F. Bultot (Hydrol. Sect., Roy. Meteor. Soc., 3 Ave. Circulaire, B-1180 Brussels, Belg.), G.L. Dupriez, D. Gellens, Climatic Change, 12, 39-56, 1988.

Information yielded by climate models about CO2 impacts is used to develop a formula for daily net terrestrial radiation under the climatic conditions of Belgium. The formula was used in a daily time-step, conceptual hydrological model to estimate moisture parameters in a Belgian drainage basin. Results are compared with present conditions.

Item #d88jul52

"Losing Coastal Upland to Relative Sea-Level Rise: 3 Scenarios for Massachusetts," G.S. Giese (State Univ. New York, Stonybrook N.Y.), D.G. Aubrey, Oceanus, 30(3), 17-22, Fall 1987.

Describes an analysis of coastal retreat by passive submergence (as opposed to erosion), based on hypsometric curves established for each coastal community, for the present rate of relative sea level rise and two projected rates that account for global warming. Even in regions subject to rapid erosion such as Cape Cod, passive retreat accounts for most coastal upland loss under present conditions. Up to 10,000 acres could be lost by 2025 for a projected sea level rise of 1.57 feet. Future research should examine other types of climate change impacts on Massachusetts, especially altered storm climatology.

Item #d88jul53

"Host Suitability of Phaseolus lunatus for Trichoplusia ni (Lepidoptera: Noctuidae) in Controlled Carbon Dioxide Atmospheres," W.L.A. Osbrink (Res. Educ. Ctr., Univ. Florida, 3205 College Ave., Ft. Lauderdale FL 33314), J.T. Trumble, R.E. Wagner, Environ. Entymol., 16(3), 639-644, 1987.

Elevated CO2 at 1,000 ppm increased the consumption of foliage by the insect as well as plant growth, compared to the ambient level of 340 ppm. Effects of high, medium and low fertilizer rates on host and pest were studied. Because percent leaf area of plants consumed by T. ni larvae was not affected by CO2 concentration, increased plant growth resulting from elevated atmospheric CO2 may benefit the plant proportionally more than the insect.

Item #d88jul54

"Ice Sheets and the CO2 Problem," C.J. Van Der Veen (Inst. Meteor., State Univ., Utrecht, Neth.), Surv. Geophys., 9(1), 1-42, Mar. 1987.

Discusses the CO2 warming and its basic mechanisms, focusing on the effects on the ice sheets of Greenland and Antarctica. A 2-4° C warming and intensification of the hydrologic cycle are expected by the second half of the next century. The Greenland ice sheet will diminish, but Antarctica's should grow because of increased snowfall. The unstable West Antarctic ice sheet is also considered; no dramatic changes are expected within the next century.

Item #d88jul55

"Projected Increases in Municipal Water Use in the Great Lakes Due to CO2-Induced Climate Change," S.J. Cohen (Can. Clim. Ctr., 4905 Dufferin St., Downsview, Ont., Can.), Water Resour. Bull., 23(1), 91-101, 1987.

Scenarios of warmer climate produced for the region by two different general circulation models were combined with a regression model of potential evapotranspiration for individual Canadian and U.S. cities. Projected per capita water use will increase by a small amount, which will probably have only a marginal effect on water supplies in the Great Lakes basin. A similar approach could be used to study impacts on water use by agriculture and the power industry, as well as the effectiveness of water policy initiatives.
