Though climatic geomorphology has long been perceived as providing a realistic framework for landform analysis, only the arid , nival and glacial systems and some constructional forms on the coast are readily identified in the landscape, present
En moyenne annuelle, la brume (dont l'albedo varie de 0,8 à 0,98) serait responsable, sur l'Arctique, d'un réchauffement de la basse atmosphère compris entre 0,1 et 1 C. (JPB).

Alors que les modèles de simulation du climat conservent le plus souvent une maille de 200 à 300 km et s'en tiennent aux dispositions moyennes, il existe une forte demande pour que le climat futur soit décliné à l'échelle locale et en termes de
phénomènes extrêmes. D'où la mise au point de modèles à aire limitée ou offrant la possibilité de faire varier la résolution horizontale. - (JPB)

This paper defines the climatic and environmental conditions that determine the limits and continuity of permafrost occurrence, in the Canadian context. The analysis utilizes a functional model that links air, surface and permafrost temperature
through seasonal surface transfer functions and subsurface thermal properties. The temperature of permafrost (TTOP) results from the interplay between the air temperature, the nival (snow) offset and the thermal offset. These offset values vary
The roles of texture and structure in the water retention capacity of burnt Mediterranean soils with varying rainfall
The objective of this work was to evaluate whether different soil conditions at burnt sites result from fire or from different climatic conditions (average annual precipitation). For this purpose, an altitudinal transect affected by forest fires
Article gives a review of sea floods on Slovenian cost with emphasis on their formation, extent and consequences. Sea floods are occuring every year, but they vary in frequency and extent. Consequently, the damage caused by floods also varies. Sea

Climate-human society interactions during the Holocene
Mass balance of glaciers in mountain areas varies not only with altitude and regional position but also with aspect, gradient, glacier size, glacier type and detailed topographic position. These factors are combined here in models of how glacier
altitude varies, tested with data for the Alps edified from the World Glacier Inventory.

National Weather Service data published in USA Today archive are used to analyze daily hottest and coldest places in the lower 48 states over a 10-year period (1995-2005). The location of hot and cold places vary considerably depending on what
climate measure is used to determine mean temperatures. The results of this study show that there is no single place in the conterminous United States that can claim to be the hottest or the coldest.
to document how and why aerosols vary over time and space. It reveals that temporal and spatial variability in aerosol emissions is superimposed by temporal and/or spatial variability in meteorological and climatic factors. This interaction between aerosol
This paper describes the nature of aerosols, their influence on the climate system and methods for quantifying atmospheric turbidity, which is the total column amount of aerosol. The main focus is a review of turbidity research that serves

presented by the IPCC, and they determined that mean water consumption should increase by an average over 3% by 2050, but the climate-induced change in consumption varies considerably across census tracts.
In this study, the AA. determine the empirical relationship between water consumption and variations in temperature and precipitation. They find the sensitivity of water consumption to either climate variable is positively related to the percent
A partir de mesures effectuées à bord de satellites au cours de ces 2 dernières décennies, il a été prouvé que la constante solaire varie à différentes échelles de temps et avec des périodicités identifiables. Il est donc nécéssaire d'étudier le
rôle de ces variations sur les changements climatiques terrestres. Il semble bien que le soleil a joué un rôle dans le changement du climat ces 500 dernières années, cependant, il existe peu de preuve de l'impact des variations des radiations sur la
Global mean sea level rise is a potentially sensitive indicator of climate change. Global warming will contribute to worldwide sea-level rise (SLR) from thermal expansion of ocean water, melting of montain glaciers and polar ice sheets
. These effects vary widely in their relative importance; methods of filtering some of these contamining signals are discussed in this paper. Factors that may contribute to the recent SLR will be reviewed and various future projections will be assessed.

that the climatic conditions governing sedimentation during the Holocene changed from humid and subhumid to the present subarid conditions, but was interrupted by a phase of increased humidity. The varying character of solid bedrock caused different weathering
products, which are reflected in the varying geochemical and mineralogical composition of lake deposits.
Valley form varies throughout the study area. The region is too small to have any climatic variances, nor is the vegetation significantly different. These valley forms are primarily a function of lithologic discontinuities, structure, and multiple
