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

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

Variability is one of the characteristic features of polar geoecosystems. On the meso- and macro-time scales, the variability of geoecosystems can be expressed in relation to : irregular interannual changes, multi-year cyclic changes, year-to-year
directional changes and anthropogenic changes. Polish multidisciplinary research concerning the physical, chemical and biological processes in the region of Admiralty Bay (King George Island, South Shetland Islands) demonstrates such variability.

This paper discusses global environmental problems such a climate change and biodiversity conservation, and reviews policies to address them. Two broad groups of instruments are analyzed: taxes and marketable permits. The paper concludes
Diurnal changes in the isotope composition of atmospheric CO2 in Kraków
Global change: polish perspectives 2
The AA. present the preliminary results of measurements of diurnal changes in the isotopic composition of atmospheric CO2 in Kraków. They present four experiments done in different seasons of the year. Results show that the isotope composition
Contemporary climatic changes occur on global, regional and local scales. The climate of the Raba River valley in the period 1971-1992 is presented as an example of the changes that can take place in the character and structure of a local climate
. The regional scale trends of air temperature changes for the Carpathian Foothills are presented along with local scale transformation of climatic relations in the Foothill valleys produced by the construction of a reservoir. It is also demonstrated how
an analysis of trends in air temperature changes can help detect inhomogeneities in observation series made for different types of topoclimate.
A stochastic weather generator as a tool for the construction of climate change scenarios
Global change : polish perspectives 3
Crop-growth simulation models need long-term daily weather data to assess possible modifications in farm production in changed climatic conditions. Here, is presented a stochastic weather generator LARS-WG that provides synthetic long time series
of climatic elements. The generator gave an adequate simulation of weather parameters for a selected station (Zamość) in Poland and was next applied to construct climate change scenarios on the basis of UKTR model data.
Anthropogenic changes in the suspended load transportation by and sedimentation rates of the river Vistula, Poland
Evidence is presented that regulation works on the Vistula channel have introduced very significant and rapid changes in the magnitude of river load transportation and sedimentation. It is acknowledged that human interference represents the most
significant cause of change in the Vistula catchment within historical times. The alluviation of the Vistula valley floodplain as described here, which was initiated about 150 years ago, may be compared with the equally rapid changes of load transportation
This paper discusses the output of Polish climatologists dealing with climate changes. Climatic forecasts for Poland are presented (with the development of the greenhouse effect taken into account). Circulation factors take part in forming climate

This paper analyses long-term variability in the number of days with precipitation in Kraków in relation to changes in atmospheric circulation. This paper provides a certain contribution to the reconstruction of the climate in the first half
The application of analysis of diatom coupled with other siliceous microalgae and sediment dating allowed for the determination of the progress of deterioration in environment of the Gulf of Gdańsk. It is shown that the change in the diatom flora
