Climate ; Global change ; Greenhouse effect ; International agreement ; Policy
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

In this survey we contribute to the evaluation of the dependence between water balance of big dams towards climate and notably towards the rain and the evaporation. The modest and variable rain contrast with a high and less variable evaporation

Longest series of climatic data for several meteo stations in Ethiopa were collected. They include 14 raingauges and 5 thermometric stations located in the highlands and in the Main Ethiopan Rift Valley and ranging in elevation from 1200 to 2500 m
a.s.l. These data were statiscally analysed in order to provide a reliable base for the characterisations of climate in this part of the world and to investigation on the occurence of climatic trends with respect to desertification process that is widely
Over the last decades there has been an increasing growth in urban areas, associated with the growth and development of the surrounding and industrial areas. This urban growth has a direct impact on local and regional climate conditions, causing
them to become substantially different from those in suburban and rural areas. Climate research and investigation in urban areas, as well as validation of climate models, will only be possible with resort to the results of local meteorological
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
and vulnerability of ecosystems necessitate a local parameter representation, therefore a finer grids. Variations of climatical parameters of representative stations have been determined from observations of the period of reference 1961 - 1990. Futures scenarios
will be for each zone by using results MAGIC / SCENGEN model. But here exists of uncertainties on due regional climatical impacts mainly of a coarse resolution of the GCM and the parameterisation of phenomena in under - grilles. - (BJ)
About 70 examples of Quaternary fauna in China's tropics are enumerated in this paper. Of which about 40% of the examples can be found even in cooling stages, showing the smaller amplitude of climatic fluctuation during Quaternary. According
to the temporal and spatial distribution of tropical faunas, the following characteristics of climate variation can be evidenced : 2 main cycles in Early Pleistocene, 3 main cycles in Middle Pleistocene, 2 main cycles in Early Pleistocene, 2 main cycles in Late

From a downscaling of a GCM, we have developed a climate scenario for Mali. The sensibility assessment of the rainfall and the temperature values has been done. It show that a wet period will be produced by an increasing of 10 % of the mean level
of this article is to discuss the influence of variations in climatic conditions. Newly compiled time-series are evaluated as climate proxy data and some methodological problems are examined.
Quelques particularités de la variabilité pluviométrique dans un climat de transition : cas du département du Zou au Bénin - Afrique de l'Ouest
Les relations Climat-Homme-Climat
The study field is at means-Benin and corresponds to the transition climatic zone between subequatorial climate in the south and soudanien climate in the north. The study shows that with pluviometric pejorations started since 1970, soudanien climate

An appreciation of the degree of global climatic warming over the past century has led to speculation concerning possible impacts on species, communities, ecosystems and overall global biodiversity. Paleobiogeography, in particular, has been called
