- GENERAL INTEREST AND POLICY
of Global Warming Potentials to Carbon Dioxide Emission
Scenarios," K. Caldeira (Global Clim. Res. Div., Lawrence
Livermore Nat. Lab., POB 808, L-256, Livermore CA 94550), J.F.
Kasting, Nature, 366(6452), 251-253, Nov. 18, 1993.
The concept of a global warming potential for CO2 is central
to developing emissions policy, but has been derived from
relatively simplified models of the carbon cycle. Calculations in
this paper show that the global warming potential of CO2 is a
useful concept despite complexities in the climate system and
uncertainties in future emissions.
Dynamics and Sequestering of Carbon in Tropical and Subtropical
Soils," W.G. Sombroek (FAO, Via della Terme di Carcalla,
00100 Rome, Italy), F.O. Nachtergaele, A. Hebel, Ambio, 22(7),
417-426, Nov. 1993.
Refines current estimates of organic soil carbon pools using
the recent FAO/Unesco Soil Map of the World, emphasizing
the role of sound organic-matter management. Explores the
possibilities for soil-carbon sequestering to offset climate
change, and the possible effects of climate change on the
soil-carbon pool. Recent research on the CO2 fertilization effect
and the associated antitranspiration effect due to elevated CO2
indicate that a positive influence on soil organic carbon levels

"Global Warming and Public Health: An Appeal for
Coordinated and Early Action," S.T. Hussain (Dept. Anatomy,
Coll. Medicine, Howard Univ., Washington, D.C.), R.L. Hayes,
424-429. Policy makers must increase the funding for research and
public education on this topic.
"Potential Effects on Health of Global Warming," A.
Haines (Univ. Coll. of London Med. Sch., Whittington Hosp.,
Archway Site, Highgate Hill, London N19 5NF, UK), M. Parry,
430-448. Reviews direct and indirect potential impacts on health,
which could strongly influence public perceptions of climate
change and hence the degree to which control policies are
followed. The difficulty in predicting effects argues for a
"Global Environmental Issues and Electric Power in the
Twenty-First Century," G.M. Hidy (EPRI, POB 10412, Palo Alto
CA 94303), D.F. Spencer, 449-468. Examines the tradeoff between
the future contributions to human well-being from electricity and
the possible benefits of CO2 emissions management. Examines
technological options for such management. Aggressive development
and demonstration of technologies will insure cost-effective
options if they are needed.
"Cost-Effective Control of Long-Run Temperature Change:
Tradeable CO2 Permits," R.F. Kosobud (Technol. &
Environ. Policy Sect., Argonne Nat. Lab., Argonne IL 60439), D.W.
South et al., 488-501. Proposes an "evaporative"
marketable CO2 emissions permit system, which could provide the
most cost-effective, graduated emissions control.
Methyl Bromide Issue," B. Chakrabarti (Central Sci. Lab.,
London Rd., Slough, Berks SL3 7JH, UK), C.H. Bell, Chem. &
Industry, 992-995, Dec. 20, 1993.
Summarizes the extensive uses of this ozone-depleting
fumigant, impending changes in its use specified under the
Montreal Protocol, and the development of alternative
Effects of NAFTA on the Environment," R.K. Kaufmann (Ctr.
Energy & Environ. Studies, Boston Univ., 675 Commonwealth
Ave., Boston MA 02215), P. Pauly, J. Sweitzer, The Energy J., 14(3),
217-240, July 1993.
Impacts related to climate change discussed here include the
relation between income and carbon emissions, and increased trade
