Description
English: delta-O-18 from the NGRIP (black) and EPICA (blue) ice cores.

delta-O-18 is a temperature proxy. Higher values are warmer. The left hand side shows the current interglacial. The right hand side is the previous Eemian interglacial which is incomplete in the NGRIP data. During the glacial period the NGRIP core shows clear signs of Dansgaard-Oeschger events which are muted in the EPICA core.

By William M. Connolley.
