We present the main features of the international agreements on the climate change : the intergovernmental Panel on Climate Change (IPCC) created in 1988 and the United Nations Framework Convention on Climate Change (Rio, 1992). Recent developments

Crop models have been used to evaluate the impacts of the climate change on the phenology and the quality of the grapevine Vitis vinifera L. in the French Mediterranean area. The results of the study indicate that the climate change might shorten
Impact of an anthropogenic climate change scenario on the frequency distribution of temperature and precipitation over France is studied with a numerical simulation calibrated with observed daily data from the synoptic network. - (BJ)

This analyse focus the global change and its regional and local manifestations on the south of Brazil, on the Parana's State. Dates from eight places-cities were analysed and has shown an increase in air temperature, notably on the last decade
Mise en évidence d'un changement dans la variabilité pluviométrique au Bénin (Afrique de l'Ouest)
This research shows the changes occured in pluviometric variability in Benin. In effect, the comparative diagnosis of the number of rainy days, pluviometric indices and tendancies realised using the graphic method and the frequent analysis permit
to notice the changes in the statute of pluviometric variability over the periods 1941-1970 and 1971-2000. - (BJ)
Changements et variabilité de la durée de la persistance et de l'épaisseur d'une couche de neige en Pologne au XXe siècle
The aim of the study is to investigate long-term changes and variability of snow cover in Poland in the 20th century. The investigation involved homogenised data on the snow cover duration and seasonal maximum depth of snow cover from 66
Les changements de la température à la surface de la mer Baltique dans la région de la baie et de la fosse de Gdańsk et leurs relations avec la température de l'air (1871-1992)
This article has presented the analysis results of the changes in the sea surface temperature (SST) in the Baltic Sea observed in 2°x2° grid with its centre co-ordinates 55°N and 19°E (mean monthly values, data source COADS ; Slutz et al. 1985
)°C). The greatest increase in the SST occurs in the months in which the influence of radiation factor on the thermal balance of this area is not very significant. The influence of the circulation factor may be accountable for the changes in the SST
Past studies about the impacts of climate change in agriculture have mainly considered the possible effects of future climate scenarios for the end of the century. However, the last fifteen years have shown a significant increase of temperature
The paper presents the analysis of the variability and tendencies of change (trends) of unfavourable biothermal conditions in Cracow. The study used the diurnal records of air temperature from Cracow in the years 1826-2002. It was concluded
The study focuses on rainfall changes over South Africa as simulated from the ocean-atmosphere coupled general circulation model ARPEGE/OPA, under the IPCC B2 scenario. Simulations for 1970-1999 are compared with observed data in order to assess
Scenarios of the future climate to Congo has support soft use MAGICC / SCENGEN (general circulation model - GCM). However, grids of this model have a resolution too great (5° of latitude x 5° of longitude), while studies of climate change impacts
