THE melting Greenland icecap may have caused the rise in sea level during the last interglacial period 125 000 years ago, say researchers in the US.

The West Antarctic ice sheet was the main suspect, because it is partly below sea level and prone to melt rapidly. But an analysis of oxygen isotopes by Kurt Cuffey of the University of California at Berkeley and Shawn Marshall at the University of Calgary shows Greenland was up to 8 °C warmer,
