Our Changing Planet: The FY 1993 U.S. Global Change Research Program, Committee on Earth and Environmental Sciences, 79 pp., 1992. Order from the Committee, c/o Forms & Pubs., Nat. Sci. Foundation, 1800 G St. NW, Rm. 232, Washington DC 20550 (202-357-7861).

Proposed is a 24% increase over FY 1992. The highest priority is given to determining whether and to what extent human activities are changing or will change the global climate system. Included are a restructured Earth Observation System and support for investigations into stratospheric ozone, human interactions, solid Earth processes and solar influences. Summarizes recent research progress.

Item #d92jul104

Reports of the CC1 Working Group on Climate Change Detection (3 volumes), World Climate Data & Monitoring Program, 100+ pp., Mar. 1992. Available from Public Info. Off., WMO, POB 2300, 1211 Geneva 2, Switz.

Proceedings of a working group that met in Oct.-Nov. 1991 to outline the status of the World Meteorological Organization's Climate Change Detection Project, CLIMAT code adaptation, and tracking and transmission of climate system monitoring information.

Item #d92jul105

RISE: Radiative Inputs of the Sun to Earth. A Research Plan for the 1990s on Solar Irradiance Variations, 31 pp., 1992. Div. Atmos. Sci., Nat. Sci. Found., 1800 G St. NW, Washington DC 20550.

Lays out a five-year, $11-million budget for NSF support of ground-based solar and stellar photometric studies that will contribute to the U.S. Global Change Program. The data are essential for improved physical understanding of the sun's present, past and future radiative output variations. The main ground-based instrumentation recommended is the design, construction and deployment of two precision solar photometric telescopes. Recommendations for space observations to be conducted by NASA are also presented.

Item #d92jul106

Bibliography for the U.S. Geological Survey Global Change and Climate History Program 1990-1991, J. Kelmelis, H. Lins et al., Eds., 36 pp., 1992. Available from Asst. Director for Research, USGS Global Change Prog., MS-104 Natl. Ctr., Reston VA 22092 (703-648-4450).

Lists publications (citations only) on global change research from the USGS. Included are book and journal articles, USGS reports, and abstracts and nonrefereed publications.

Item #d92jul107

Calculating Future Atmospheric CO₂ Concentrations (Res. Tech. Paper 22), I.G. Enting (CSIRO, Div. Atmos. Res., Pvt. Bag 1, Mordialloc, Vic. 3195, Australia), 32 pp., 1991.

Reviews current techniques for calculating the future atmospheric CO₂ concentrations to be expected from various possible patterns of CO₂ release. Uses 1990 IPCC report and other results to show the CO₂ concentrations expected from adopting the Toronto target of a 20% reduction in CO₂ emissions by the year 2005. Critically examines assumptions underlying the calculations.

Item #d92jul108

Report on a National Workshop on Gas Hydrates (DOE/METC-91/6124), 44 pp., 1991. NTIS: DE91-016654; $17.

The immense amounts of methane held in hydrates could have major climate and resource implications. However, research has been disjointed, and we lack a broad understanding of processes that affect hydrate development and the chemical and geological controls of these processes. A research program is detailed.

Item #d92jul109

Technical Bibliography: William B. Grant has compiled the following bibliography, available without charge from him at NASA Langley Res. Ctr., MS 401A, Hampton VA 23665 (tel: 804-864-5846).

Impacts of Volcanic Aerosol on Ozone, Mar. 1992. Contains over 65 citations, beginning in 1965, with over half having been published from 1988 to 1992, taken primarily from the reviewed literature and books.
