There are numerous possible expensive research projects that could address each of the many facets of the implications of global climate change. The paper describes a systematic process to identify and the structure the objectives of research
on globalchange. The result is a hierarchy of 81 important research objectives.
Les changements climatiques ont des conséquences directes sur le système alimentaire et la vulnérabilité des moyens de subsistance. Un projet pilote tente de déterminer l'adaptabilité des sociétés et les répercussions économiques des changements

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
and permafrosts, or large pluvial epochs of general warming. At present an ever greater impact on the changes of the hydrological cycle is produced by human activities and the recent climatic warming.
After outlining the background of the IGPB (International Geosphere-Biosphere Programme), the AA. conclude that understanding of globalchange cannot be gained fully without reconstruction of earlier landscape processes, more sophisticated modelling
of the dynamics of present-day landscapes, analysis of the causes and consequences of anthropogenic changes in specific regions, appraisal of the conditions in which societies may respond to the new knowledge of those changes, and a greatly enhanced geographic

Globalchange is complex in 2 senses. First, multiple interactions are involved. Second, the interactions include nonlinear relations. Most interesting problems in physical geography are so constructed. In this paper, the A. examines some
of the consequences of nonlinear relations in the response of the alpine treeline to ecotone to global climatic change.
Major changes are occurring in the global warming debate. Popular alarmist views are giving way to more balanced assessments of the situation. There is now greater emphasis on the lack of consensus among climatologists on fundamental scientific
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 globalchange. Some perspectives of the further development of the international and interdisciplinary Earth Transformed project are also discussed.

If predicted global climatic changes occur, New Zealand is likely to experience changes in temperature along the north-south axis, but changes in rainfall across this axis, with more rain in the west and less in the east. Such climate changes

Global environmental change provides the discipline of geography with what could be its greatest contemporary challenge. The AA. feel that a postmodern geography would be better placed to work with issues relating to global environmental change

This progress report on global warming will focus on : the outcome of the Kyoto conference and its significance for future global climate change, and the current state of the global climate system, in particular the surface air temperature record
and its interpretation. The A. will also consider recent work that has a bearing on just how significant current and future global climate warming may be for the planet and for the life which inhabits it.

This paper builds on previous geographical and social science work at the boundaries of climate change by(re)asserting the significance of the territoriality of the national state in global climate negotiations. Using post-political consensus
as a theoretical framework and drawing upon examples from climate change negotiations like Kyoto and Copenhagen, it argues that it is too premature to fetishize the consensus of, and collectivism between national states in global climate politics. As geographers
, ‘territoriality’, both as a material and discursive device, is fundamental in, and constitutive of, how we interpret and understand climate change and the politics thereof.
