On the basis of the newest glaciological & oceanological data, global changes in the atmosphere's temperature & gas composition over the last climatic cycle are described & a strict correlation between them is demonstrated. Paleographic analysis demonstrates the nature of changes of geographic zones & landscapes in the northern hemisphere during the Upper Pleistocene & Holocene epochs. Climatic changes & glacierization in the 20th century & the progress & possible causes of the rise of the world ocean level are analyzed. Using the well-known forecase of a global temperature rise in the 21st century, possible patterns of change in natural conditions in the North, in temperate zones, & in southern latitudes of the northern hemisphere are considered. It is stressed that anticipated global warming will not necessarily lead to a global environmental crisis, but will signify a transition to new conditions calling for profound societal adaptation. 2 Illustrations, 30 References.

AbstractFollowing the prolonged drought at the end of the 1980s in the south east of the UK, Anglian Water undertook (a) to review the reliable yields of their resource systems and (b) to investigate the potential risks associated with alternative future investment programmes. One of the major identifiable risks is climate change, and there is a clear need to understand how different scenarios of climate change could affect the reliable output of existing sources, and thereby affect investment programmes.This paper highlights the approach which was adopted to model climate change impacts on rainfall, and on the limitations which exist for this type of assessment.

In September 1983, IIASA and UNEP, together with the Austrian Government, gave support to an International Study Conference on The Sensitivity of Ecosystems and Society to Climatic Change, which was attended by scientists from 17 countries. The conference was divided into two parallel workshops - on climate impacts in cold and in semiarid regions. This report brings together eight papers that ultimately arose from discussions in the "cold" workshop. In most cases they report the results of preliminary experiments relating to climatic change, and represent the outcome of a piece of "pilot" research by IIASA for UNEP to test the research methodology before applying it in a wider context. Of the variety of techniques and concepts applied, two deserve mention here. The first is the mapping of impact areas by the spatial shift of isopleths or boundaries. The second is the construction of a hierarchy of climate, impact, and economic models to trace the cascade of climate impacts through biophysical, economic, and social systems. This report marks the completion of IIASA's pilot study. The full research project, funded jointly by UNEP and IIASA, is now being implemented in 12 case studies through a collaborative network of 70 scientists. Its purpose is to evaluate the impact of climatic change and variability on food production in climate-sensitive areas, and to consider appropriate policies of mitigation.
