Potential Impacts of Climate Change on Electric Utilities (Report
88-2), ICF Inc. (for NYS Energy R&D Author., Two Rockefeller Plaza, Albany
NY 12223; F.V. Strnisa, Proj. Mgr.), 119 pp., Dec. 1987.
Cosponsored by the Edison Electric Institute, the Electric Power Research
Institute and the U.S. Environmental Protection Agency, this study compared
estimated impacts over the next 30 years on a southeastern United States
utility, with those for the Northeast (upper and lower New York State). "High"
and "low" temperature change scenarios are considered, the former
representing the highest estimates by current general circulation models. For
the high scenario, the change in peak demand is greater for the Southeast, but
generating capacity increases required are similar, ranging from 10-21% of base
case for the period, or the equivalent of one or two large central power
stations in each region. Added annual electricity production costs range from
$48-241 million in New York, depending in part on the assumptions concerning
climate change impacts on hydroelectric production. The report discusses the
extensive uncertainties inherent in the analysis. Although large impacts are not
imminent, their importance is likely to increase, and utility planning should
take account of climate change impacts immediately. Extensive suggestions are
given for further research on predicting likely climate change and modeling
impacts on utilities.
Determination of Broad-scale Land Use Changes by Climate and Soils
(WP-88-7), F. Brouwer (Inst. Appl. Syst. Analysis, A-2361 Laxenburg, Austria),
21 pp., 1988, $5.
Addresses some major environmental determinants for broad-scale land use
changes under a possible climate change scenario for Europe. Focuses on changes
in land degradation mechanisms such as compaction, erosion, toxification,
reduction of nutrients and organic matter, and salinization, all of which
severely influence land use.
Untersuchungen uber die voraussichtlichen Langzeiteffekte einer
CO2-bedingten Klimaveraenderung auf die einheimische Vegetation.
Abschlussbericht (Investigation of the Prospective Long-Term Effects of
CO2-Induced Climatic Alterations on the Native Vegetation. Final Report), D.
Overdieck (Fachbereich Biol./Chem., Osnabrueck Univ., FRG), 250 pp., 1987. In
German. Available through NTIS, order no. TIB/B88-80653/XAB, $42.00.
Long-term experiments were conducted on herbaceous species at natural
conditions on simplified stands of Middle-European grassland vegetation, using
atmospheric CO2 concentrations of 270 to ppm. With elevated CO2, growth is
enhanced and usually more material is shifted to storage organs. The effects are
enhanced by increased light intensity and by temperature, but only up to 35° C.
CO2 enrichment alters the competition among mixed species. Two mathematical
models were developed for effects of CO2 enrichment on grassland ecosystems.
