Summary

The authors present a detailed stable-isotope record for the full length of the Greenland Ice-core Project Summit ice core, extending over the past 250 kiloyears according to a calculated timescale. They found that climate instability was not confined to the last glaciation, but appears also to have been marked during the last interglacial and during the previous Saale-Holstein glacial cycle. This is in contrast with the extreme stability of the Holocene, suggesting that recent climate stability may be the exception rather than the rule.
