This publication considers issues of global change versus global warming, using climate history graphics to illustrate the earth's climate variability from paleoclimate research. Topics discussed include: the hydrological cycle and its relevance to fisheries and the evolution of species and fisheries variability, production variabilities and changes in vulnerability owing to constant dynamics of ocean motion affects, bioindicators, spatial and temporal scales, regional ecological responses, examples of ocean ecosystems defined by seasonal thermal properties, synchrony and systematic transitions.
