From high resolution records, such as the chemical tracers in ice-cores, the events can be dated with unpresedented accuracy with the aim of establishing cause and effect relations in the climate dynamics. A still much debated periodicity in timing of the events would also point to possible causes. Stochastic - or coherence resonance mechanisms have resently been suggested to explain the spectral dominance of a period of 1470 years. The aim of the session is to present and bring together the various paleoclimatic dating results and the recent results in the paleoclimatic timeseries analysis and climate modelling.
