Other studies indicate that the peak sea level during the latest interglacial was a few metres higher than today, implying that peak temperatures were higher.
Recent evidence from ice - core drilling in Greenland indicates that similar fluctuations also occurred during the previous interglacial period, possibly due to rapid changes in ocean circulation.
Ice core observations indicate ice during the last interglacial at sites (white dots), Renland (R), North Greenland Ice Core Project (N), Summit (S, GRIP and GISP2) and possibly Camp Century (C), but no ice at sites (black dots): Devon (De) and Agassiz (A).
