This paper investigates the likely changes in the thermal climate of the Pennine region that would be associated with different climate change scenarios. Estimates of future temperature change are converted into attendant changes in climatic

This report examines recent developments in relation to present (and anticipated future) sea level, Quaternary sea-level fluctuations, the response of coastal landforms to sea-level change and the use of biological indicators of sea-level change.

There is evidence that, between hydrological years 1931/2 and 1990/1, rainfall changed in the Algarve. There was an annual rainfall increase (+9%) and a (7%) increase in rainfall during the rainy period (October to February). Both trends were
statistically confirmed by parametric and nonparamertric procedures. Rainfall erosivity and land degradation are related to rainfall regime. The Algarve's rainfall erosivity increase (+17%) was more pronounced than annual and seasonal rainfall changes.
Problems of the changes in the school system in the post-communist countries: a Polish case
Experiences and problems related with the attempts of the transformation of school systems in the post-communist countries are discussed and the analysis of the Polish general secondary schools is analysed in details. The general change
in the educational system cannot be done merely by non-public schools if not supported by the public administration. The latter is, however, too inert to assist the changes and needs reconstruction itself. - (DG)
Channel changes following headwater reforestation: the Ganaraska River, Ontario, Canada
This study examines channel change in a southern Ontario basin that has been partly reforested over the past 50 years, and tests the ability of an equation to explain these changes.
Changes of river channels in Europe during the Holocene
Changing river channels
The A. describes the diversity of existing river channels on the European territory and their evolution during last 18 ka BP. He discuss the role of various factors starting from climatic changes influencing the hydrological regime, the tectonic
factor, lithological factor, deglaciation, marine transgression and anthropogenic impact. In reality the changes in the channel pattern depend on the combination of various factors. - (DG)

The AA. discuss changes of precipitation in China due to growing greenhouse gases using GCM model assuming the IPCC Scenario. An increasing greehouse effect will lead to precipitation increases mostly in north of 30°N for winter, and strongly

The recognition of alternating flood- (FDRs) and drought-dominated regimes (DDRs) in coastal rivers of New South Wales has helped to explain some of the changes in channels and floodplains observed in more recent times. On these bases the aims
of this paper are to predict channel and floodplain changes for two likely future scenarios: for the first a probable imminent shift back to a drought-dominated regime (DDR), the second based on the imposition of a greenhouse climate, first on a waning DDR
