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 global change. The result is a hierarchy of 81 important research objectives.
Arid area ; California ; Climatic variation ; Global change ; Precipitation ; Runoff ; Semi-arid area ; United States ; Watershed
The purpose of this paper is to assess the hydroclimatic response of the semiarid portion of the Mono Basin to small changes in long-term mean temperature and precipitation. A climatic water budget model for the Cottonwood Creek and Bridgeport Creek
watersheds in the north-central portion of the Mono Basin is employed to simulate existing hydroclimatic processes and the alteration of these processes in response to climate change.

The approach allows the temporal impacts of climate change to be determined, measured in terms of the degree of adaptation of the agricultural sector to climate change. Use is made of a world agricultural commodity markets model, constructed
Climatic changes in Southern Poland, including the Carpathian Mountains are shown in regional and local scale. There are discussed: changeability of the circulation indices during the winter season and fluctuations of the air temperatures based
on the instrumental observations in the mountain stations. The influence of climate is referred to the secular changes in the width of tree rings in Tatra Mountains and the thermal feelings of human body. Local changes of the radiation inflows are characteristic

This paper concentrates on impacts that regional and global climate changes may have on deltaic ecosystems using deltas in the Aral Sea basin as an example. In addition to an assessment of regional climate change and variability
and their relationship to environmental conditions within inland river deltas, this paper examines the past development of the deltas (including consequences of human-induced alteration of the regional hydrologic cycle), climatic trends and ecosystem changes within them
, and the relationships among future climatic and ecosystem changes that may occur.

The paper begins by defining a convention. It examines the selection of convention sites, documents the surge in convention activity, describes cross-sectional changes (1964-65 to 1990-91) in the spatial patterns of convention attendance
in the United States, and explores the implications of these patterns for students of social change and American metropolitan evolution.

Quelques généralités sur le changement global et les résultats d'une étude sur les variations du glacier Horcones Supérieur, région de l'Aconcagua, Mendoza. - (MZ)
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 diagnosis of climate change in Cracow against a background of circulation and local conditions
The multi-annual variability of thermal, solar and cloudiness conditions in Cracow was examined from the point of view of the impact of natural and anthropogenic factors on the climate change. The analysis concerned the annual air temperature range
(RAT) and daily ranges of air temperature (DAT) in january and july. Special attention has been paid to the climatic trends and changes of climatic continuity. Long-term changes of RAT reflect the impact of the circulation factors, these of DAT

Aux latitudes moyennes, les observations phénologiques s'avèrent d'un très grand secours pour détecter et suivre un éventuel changement climatique global. Exemple de la partie orientale du continent nord-américain avec, depuis 1961, une feuillaison

This is the second-year report on recent environmental changes at high northern latitudes (Boreal-Arctic). As in the previous one (Kullman, 1992) subjects and references are selective rather than comprehensive, with the overall aim to confront
This paper examines some likely consequences of climatic warming on the runoff and sediment regimes of a very diverse group of fluvial systems. It is suggested that research on climatic change impacts should focus on the ware and sediments
Floodplain change in the Glenmalure Valley, South-East Leinster
This study describes reach-scale changes in floodplain form over a 25 km stretch of the Glenmalure River in south east Leinster and explains this variability in terms of downstream changes in geomorphological processes and geological inheritance
. The five floodplain types presented in this study provide important evidence of spatial and temporal changes in a river's ability to modify control variables within the constraints of geomorphic antecedence, particularly the buried bedrock topography

Since models of global warming predict that climatic changes will be greatest in the Arctic and might already be in progress, it is prudent to attempt to understand the rapidly changing thermal regime on Eurasian cold regions. In this paper
the A. tries to evaluate the probable catastrophic implications of global climatic change in the cold regions of Eurasia. The impact on Man activities in permafrost regions is discussed.

Regional climate change for the Baltic Sea is discussed first, with particular emphasis on recent findings for sea level (mean and extrema) and storm intensity. More thought is being given to the general problem of land (primarily arable
) degradation due to extended landward penetration of sea water due to the accelerated sea level rise (ASLR). Long-term coastline change is analysed on the basis of routine topographic and bathymetric data collected. Assessment of coast vulnerability to ASLR has
Channel and floodplain response to recent abrupt climate change: the Tyne Basin, northern England

Climatic variability ; England ; Flood ; Floodplain ; Fluvial erosion ; Fluvial hydrology ; Global change ; River bed ; Sediment transport ; United Kingdom
This paper examines the timing, nature and magnitude of river response in upland, piedmont and lowland reaches of the Tyne Basin to high-frequency (20-30 year) changes in climate and flood regime since 1700 AD. Over this period fluvial activity has
been characterized by alternating phases of river-bed incision and stability coinciding with non-random, decadal-scale fluctuations in flood frequency and hydroclimate that appear to be linked to changes in large-scale upper atmospheric circulation
patterns. The results provide a valuable guide for forecasting probable drainage basin and channel response to future climate change.
