Summary

None of the time scales hitherto applied to the Greenland O18 curve is considered reliable. The logarithmic time scales were based on the false assumption of constant glacial dynamics. The latest time scale, based on a supposed constant 2400- years cycle, seems to be based on another false assumption of constant cycles. A chronology based on indirect dating therefore seems superior.
