"Three Dilemmas in the Integrated Assessment of Climate," E.A.
Parson (JFK School of Govt., Harvard Univ., 79 JFK St., Cambridge MA 02138),
A lengthy comment relating to the following three papers, which together
address these fundamental dilemmas: interdisciplinary and critical standards;
the dependence of integrated assessments on future projections of human choice
and behavior; and how integrated assessment relates to other factors involved in
"Integrated Assessment: A Growing Child on Its Way to Maturity,"

An essay discussing the most persistent conceptions about integrated

major future challenges, the greatest of which is gaining credibility.
"Learning from Integrated Assessment of Climate Change," M.G.
Morgan (Carnegie Mellon Univ., Pittsburgh PA 15213), H. Dowlatabadi, 337-368.
Reflects on broad insights gained in the course of five years of integrated
assessment activity at Carnegie Mellon University. Discusses who the climate
decision makers are; the nature of the climate problem; studies of climate
impacts; and selected policy issues. Concludes that the issue of equity has

Offers a first attempt to grapple with the issues of quality control and
assessment of quality. Building and maintaining credibility via quality control
is a necessary condition for realizing the potential of integrated assessment.
Highlights a number of pitfalls and discusses their causes, offering suggestions
for alleviating them. For instance, tools which may be reasonable to use in
particular disciplinary, geographical, or temporal contexts may be unsuited to
the broader contexts inherent in integrated assessments of global environmental
