The current global warming controversy has sparked vigorous research activity, the ultimate aim of which is to undersatnd the effects of predicted climatic changes on both natural and managed ecosystems. Pointers from the past geological record
The AA. summarize the results of the international symposium The Earth as Transformed by Human Action held at Clark University, USA, in October 1987 with the purpose of inventorying human impact and environmental changes on the regional and global
scales, and on the conceptualization of the human dimensions of global change. Some perspectives of the further development of the international and interdisciplinary Earth Transformed project are also discussed.

The volume focuses on the immediate interface between the coastal belt and the adjacent sea waters : four broad themes have been singled out among the aspects distinctive of the italian coastal interface : the physical environment, the anthropic
environment, the ecological environment and the economic environment. - (MR)

The land-ocean ratio, periodical alternation of the epochs of orogenesis and peneplanation, time-space changes of solar influx determined the periodical changes of the global hydrological cycles with development of the continental glaciations
After outlining the background of the IGPB (International Geosphere-Biosphere Programme), the AA. conclude that understanding of global change cannot be gained fully without reconstruction of earlier landscape processes, more sophisticated modelling

Globalism can be defined as a mode of thought deriving from the practice of thinking globally, both literally and figuratively. Globalism not only informs major trends within governance and economics. It also informs environmental issues, not least
those related to global warming. It will be argued, using the example of the production of energy and power, that there may well be a built-in contradiction between globalism and the interests of landscape as the diverse place of people, polity

Evaluation of the performance of climate models under climates that are radically different from today is an integral and important component of global change research; palaeoenvironmental data are essential to this evaluation. Evaluation data must
of global syntheses. Continued discussion is required to ensure that these difficulties are ultimately overcome.
By retracing the history of climate modeling and of several scientific controversies, the A. unmasks the tacit social and epistemic commitments implied by its specific practices. The specific scientific framing of global climate change has
reinforced and been reinforced by the technocratic inclinations of global climate management. The social organization of climate change science and its articulation with the political process raise important questions about trust, uncertainty, and expertise
. The article concludes with a discussion of the political brittleness of this dominant science-led and global-scale formulation of the climate change problem and the need of a more reflexive politics.
