MIS-11 duration key to disappearance of the Greenland ice sheet
Palaeo data suggest that Greenland must have been largely ice free during Marine Isotope Stage 11 (MIS-11). However, regional summer insolation anomalies were modest during this time compared to MIS-5e, when the Greenland ice sheet likely lost less volume. Thus it remains unclear how such conditions...

Palaeo data suggest that Greenland must have been largely ice free during Marine Isotope Stage 11 (MIS-11).
