SummaryAlternative time-scales differing by 25% have been proposed for the climatic sequence revealed by deep-sea cores. Both scales are based on radiometric data. Recent evidence which is here summarized favours the time-scale which gives the smaller values for the ages of late Pleistocene events; it supports the estimate of 40 ka rather than 50 ka for the average length of the principal climatic cycle.
