\ BooknewsMaterials from this workshop give special attention to modeling and predictability, recognizing the indeterminate state of knowledge about climate systems as it derives from dual sources--intrinsic variations and external forces. Specific topics include modeling climate change; ecosystem responses to global changes, terrestrial and marine; time series analysis for aperiodic evolution; simulated annealing; and predictability and dimensionality of a simplified atmospheric model.
