The purpose of this 4th School, with the title ”Environmental Crises: S- ence and Policy” was to study the art and science of analyzing, assessing and anticipating environmental change. Among the issues considered are the observational evidence, statistical analysis and dynamic modeling as well as visioning of not–implausible changes in the environment, the changing public perceptionof the environment,functions of theenvironmentandits use. A - ries of four prominent cases, namely climate change, the emissions of gasoline lead into the atmosphere and water bodies, ?sheries policies and the mana- ment of marine oil pollution is reviewed. Obviously, many other cases could havebeenchosen,suchasWaldsterben,nuclearenergy,releaseofcarcinogenic substances, genetically modi?ed food, threat to biodiversity, import of alien species, just to mention a few. We had chosen cases which were close to the researchinterestsoftheorganizersHansvonStorchandRichardTolandtheir institutions, namely the Institute for Coastal Research of the GKSS Research Center in Geesthacht and the Centre for Marine and Atmospheric Sciences 1 (ZMAW) in Hamburg.
Deals with the natural science aspects of environmental crisesExtends the view to public reception, economical implications, and the connection between science and politics
