Cyclic palaeoclimatic variations and the future

Aaby, Bent


Recent investigations in Holocene Danish raised bogs show cyclic climatic variations with a periodicity at about 260 years during the last 5,500 years. The shore displacement in Southern Scandinavia, which is mainly influenced by eustatic sea level variations, shows a periodicity of 520 years, and the cyclic climate variation can be traced back to 7,500 B.P. This result showing a periodicity in climatic variations for most of the Holocene may tentatively be used for predicting the natural long-term trend of the future climate.
