Historical changes of the regional and global hydrological cycles in Global Change.
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.

Global Change : some concepts and problems of geographical research (a few results of the Soviet-American Project) in Global Change.
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
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

The derivation of past climate changes from observed changes of glaciers in Sea level ice and climatic change.
Un modèle temporel d'écoulement glaciaire à deux dimensions a été conçu pour prendre en compte les caractéristiques tri-dimensionnelles des glaciers dans leur régime d'écoulement et pour étudier leur réaction aux changements climatiques en termes

Change in the anthropogenic geochemical impact on the biosphere in Global Change.
The A. singles out three main types of Man's geochemical impact : 1) indirect change in the natural geochemical processes| 2) direct technogenic migration resulting in the extraction of chemical elements and compounds in some areas and their being

Coastline changes.

Coastline changes.
A summary and review of the work accomplished by the I.G.U. Commission on the Coastal Environment 1972-1984 under the chairmanship of the author. Problems of documenting and measuring coastline changes, comparing historical descriptions, maps, air
photographs, and nautical charts with the present morphology. Selective review of evidence for various kinds of coastline change around the world, starting with Alaska and circumnavigating land areas counter-clockwise. Categories of coastline change identified

Some long-term and short-term geographical tasks in the Global Change Programme in Global Change.
The geographical tasks of the Programme are determined by the essence of the geographical approach to the study of global changes of the geosphere-biosphere system. This approach aims at the resolving of two types of questions : a) what local
and regional processes and phenomena, in which way and in what degree influence the global geosphere-biosphere system : b) in what regions the current or expected global changes will most likely manifest themselves and what will be the consequences.

Persistence and climatic change

Persistence and climatic change
Changement climatique ; Corrélation sérielle ; Critique ; Géographie physique ; Mesure ; Modèle ; Persistance ; Série chronologique ; Variation climatique
Il est difficile de détecter un changement climatique lorsqu'on emploie une mesure sériellement corrélée. A partir des différentes causes de la corrélation sérielle, l'A. montre qu'il est difficile de juger du caractère aléatoire ou non des
fluctuations d'un processus climatique. Outre ses considérations sur le concept de climat l'A. ne propose pas de méthode efficace pour mesurer le changement climatique ni les gradations du changement. (Cch).

Evidence of stream response to Holocene climatic change in a small Wisconsin watershed
During the Holocene, moderate climatic and vegetational changes triggered several episodes of adjustment in the Brush Creek fluvial system. The alluvial chronology includes an episode of erosion at 7800-5700 yr B.P. corresponding to the mid-Holocene
precipitation minimum and an episode of floodplain construction at 5700-5000 yr B.P. corresponding to a rapid increase in precipitation. Holocene climatic changes have influenced the sedimentology of the alluvial deposits and soil development on them. Fluvial
adjustment is caused primarily by hydrologic and hydraulic changes related to climatic change, but there is no simple model for fluvial response to climatic change. The relationship between the direction of climatic change and the type of fluvial response
