"The Greenhouse Theory of Climate Change: A Test by an Inadvertent
Global Experiment," V. Ramanathan (Dept. Geophys. Sci., Univ. Chicago,
Chicago IL 60637), Science, 240(4850), 293-299, Apr. 15, 1988.
A succinct and technically detailed summary of the effect of increased
emissions into the atmosphere of anthropogenically influenced, radiatively
active trace gases, including chlorofluorocarbons and tropospheric ozone in
addition to CO2. This inadvertent experiment has led to radiative heating and
driven the climate into disequilibrium with incoming solar energy. Discusses
climate forcing and response, feedbacks through phase changes of water, chemical
interactions, model predictions, observed evidence of change, and unresolved
issues. The greenhouse theory has reached a crucial stage of verification; the
magnitude of recently observed warming is compatible with the theory, but its
temporal dependence is not.
"The Whole Earth Dialogue," S.H. Schneider (NCAR, POB 3000,
Boulder CO 80307), Issues Sci. Technol., 4(3), 93-99, Spring
Asserts that most large research programs to study global change or the
earth as a system have been multi-disciplinary rather than interdisciplinary.
Makes a plea for truly interdisciplinary approaches to future global change
research, using the greenhouse effect as an example. Demonstrates the possible
benefits of this approach by describing recent research on climatic influences
on crop productivity; climate modeling improved after discussions with
agronomists and ecologists.
"Is the Greenhouse Here?" R.A. Kerr, Science, 239(4840),
559-561, Feb. 3, 1988.
Researchers have recently agreed that the earth has warmed about 0.5° C
during the last century; coincident indications in several other variables will
add significantly to the evidence for greenhouse climate change. Mentions some
recent studies on stratospheric cooling, daily temperature extremes, moisture
patterns and general circulation modeling. Suggests that developing a composite
picture of change, using many variables rather than concentrating on only one,
such as global warming, will lead to the earliest detection of a greenhouse
"Changing Climate and Caribbean Coastlines," F. Gable (Marine
Policy Ctr., Woods Hole Oceanogr. Inst., Woods Hole, Mass.), Oceanus,
30(4), 53-56, Winter 87/88.
Over the next 40 years, the sea level in part of the Caribbean is expected
to rise 15-20 cm more than expected globally. Geological subsidence and the high
proportion of a coastal zone makes the islands especially vulnerable. Reviews
natural and anthropogenic sources of subsidence, projected impacts for specific
areas, and policy responses individual nations might make such as restrictions
on coastal development. Policy workshops, joint studies and research have been
initiated for the region under the United Nations Environment Program's Regional
Seas Program. A system of two or three tide gauges per island is recommended for
monitoring sea-level change.
"On the Development of Regional Climatic Scenarios for
Policy-Oriented Climatic-Impact Assessment," P.J. Lamb (Climate Sect.,
Illinois Water Survey, Champaign IL 61820), Bull. Amer. Meteor. Soc.,
68(9), 1116-1123, Sep. 1987.
Appraises alternative approaches to developing climatic scenarios, defined
as internally consistent pictures of a plausible future climate. Compares
motivations, methods, known and potential strengths and weakness, results and
credibility of empirically-based approaches and those involving general
circulation models. Suggests research needed to make scenarios more useful for
