Remarkable progress in understanding the climate system has been achieved e.g. through analysing climate records and using numerical global models for future climate projections based on reliable socio-economic scenarios. Tailored downscaling of these global projections to the regional scale for impact studies and decision making in the context of mitigation and adaptation is urgently required. Due to both its complex geophysical structure and large regional variability the Baltic Sea basin is an ideal example to be studied with high spatial resolution. In addition, the densely populated basin is under stress by further activities, e.g. agriculture and industry. The southern part of the Baltic basin is of special interest: The Polish lowland hosts in numerous lakes unique records of Late Pleistocene to Holocene sediments. Together with sediments of the Baltic Proper these deposits can be used for the derivation of complex climate proxies for a high resolution reconstruction of the regional climate. At the same time, the adjustment of agriculture and water management to the changes in climate challenge stake holders and planning agencies. In addition, sea level rise superimposed on neotectonic land subsidence leads to a continuous retreat of the southern Baltic Sea coast line and requires increasingly activities in coastal protection at the southern Baltic Sea. The conference is organised in the frame of the BALTEX program and brings together scientists, economists, engineers, politicians and managers. The conference site has been selected thoughtfully: Regionally, Szczecin represents the Polish lowland – a zone of transition between the influence of air pressure systems of the North Atlantic and Eurasia. Politically, the town stands for the ongoing process of European unification – hospitably to scientist from all over Europe and beyond. Altogether, more than 120 participants from 23 countries (11 of which outside Europe) have registered for the Conference, and 93 papers – both oral and as posters – will be presented and discussed. In this volume the abstracts are ordered by Conference session and alphabetically according to first authors’ name, where - on purpose - no distinction is made between poster and oral presentations: Session A: Marine and terrestrial proxies for reconstructions of paleo-climate Session B: Modelling of past climate change and future projections Session C: Climate and anthroposphere interactions Session D: Prehistoric communities and climate change Session E: Climate variability and change impacts on Baltic Sea coasts The numerous participants from overseas prove that the Baltic Sea basin is regarded a natural laboratory of general interest for the study of regional climate change processes. The organisers wish to thank Mr Frithjof Sterrenburg for language editing of several abstracts and Ms Kheira Dashti-Hashtjin at the BALTEX Secretariat for invaluable logistic support during the Conference’s preparation phase.
