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

Climatechange can also be observed in the countries of South-Eastern Central Europe. Author investigates the physical geographical factors which reflect the present climatechange in Hungary. According to the author an aridification process can
be observed in Hungary and its surrounding as an effect of climatechange. Changing precipitation, vegetation and soil profiles of the country are investigated. - (JS)
Arid regions are expected to undergo significant changes under a scenario of climate warming, but there is considerable variability and uncertainty in these estimates between different scenarios. The A. discusses the results of palaeoecological
reconstructions and model scenarios for 4 major arid regions (the Saharo-Arabian, Australian, Turanian and the US deserts and semi-deserts). Although palaeodata provide valuable information about possible past changes in the vegetation-climate system
Using mountain regions from around the world, the A. discusses controls of mountain climate and scales of climate features, and evaluates evidence of past climatic conditions.―(DWG)
The A., a physical geographer, addresses climatechange and feedbacks for Eurasia over longer (tectonic forcing, intermediate (Earth's orbital relations) and shorter timeframes, emphasizing that climateschange more or less continuously in response
This article reviews recent climatically extreme periods in Great Britain and presents results from the latest general circulation model (GCM) experiments showing the possible spatial patterns and magnitude of future climatechange for this region
. Results from recent ensemble GCM experiments with and without the effects of sulphate aerosols are presented. These show broadly similar changes in temperature and precipitation to previous climatechange scenarios prepared for Great Britain. These changes

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 climaticchange impacts should focus on the ware and sediments
Possible impact of climaticchange on forested landscapes in Central Europe: a review

This paper briefly reviews and tentatively discusses 1) former climaticchanges and their impact on forests, 2) the impact of climatic warming on the genetic constitution of forest trees, their physiological processes, and the possible alteration
of forest environments, 3) the changes in the latitudinal and altitudinal zonation of forests, 4) the repercussions of possible diseases and pests on the vitality of forests, and 5) changes in the function of forests in Central European landscapes.

The first part of this paper presents a review of methods used in the formulation of regional climate scenarios, while the next two parts contain an example of a regional climate scenario for Poland based on the output of the ECHAM1/LSG model

Après s'être interrogée sur le rôle du climat dans la structuration de l'espace et dans l'organisation spatio-temporelle des sociétés, l'A. détaille les principales méthodes et techniques de recherche utilisées pour mesurer, modéliser et prévoir la
variabilité du climat, afin d'estimer son impact sur les sociétés. - (JPB)
Based on previous researches, this article established the cotton climate suitability model and the risk index to analyze the cotton climate risk degree in Henan Province. The result shows that, in the last 40 years, the cotton climate risk degree
has a gradual increasing trend in which the precipitation plays a very important role. Abrupt change is an important characteristic in eastern Henan where this sudden change type has notable latitudinal difference.

change. In conclusion, the paper stresses that changes in insolation in climatically sensitive zones exceed several-fold the global radiative forcing of climatechange by CO2 and CH4, and that local and regional responses to insolation forcing decide
the primary climatic feedbacks and changes observed from past glacial-interglacial cycles, and likely to be observed in the future.
This paper addresses 4 issues that are fundamental to the debate concerning the role of CO2 and CH4 greenhouse gases in the forcing of past glacial-interglacial cycles and the role of such forcing for present and future considerations of climate
