The possible consequences of anthropogenically caused global and climate changes for human society and for the natural environment are an issue of concern to scientists, political decision makers, and the general public.
Various organizations, particularly the Intergovernmental Panel on Climate Change (IPCC), have pondered this and related issues extensively over the last 10 years. However, there are still large uncertainties about the many facets of these problems. Work toward the IPCC's Third Assessment Report (TAR), that directly supports negotiations concerning the United Nations Framework Convention on Climate Change (UNFCCC), clearly demonstrates that there is an existing need to pay attention, not only to issues at the global, but also at the regional scale. From this, it follows that there is a need to conduct regional climate impact studies for specific parts of the globe, defined by common political, economic, or environmental characteristics.
