Cyclic variations with time scales ranging from 50 to 400 yr occur in oxygen isotope ratios derived from ice cores, tree-ring index series, pollen records and sea-ice extents. Century time scale cycles can also be identified in some biological and historical records and in long-term instrumental observations. In order to appreciate the century scale cycles in the context of climatic variability in general, a brief survey of all climatic time scales is presented. The traditional interpretation that decadal-to-century scale fluctuations in the climate system are externally forced, e.g. by variations in solar properties, is questioned. A different mechanism for these fluctuations is proposed on the basis of recent findings of numerical models of the ocean's thermohaline circulation. The results indicate that this oceanic circulation exhibits natural variability on the century time scale which produces oscillations in the ocean-to-atmosphere heat flux. Although global in extent, these fluctuations are largest in the Atlantic Ocean.
