(EHSLR), which began c.10,000 BC, tailed off during the 6th millennium. Global water levels had risen by about 60 metres due to deglaciation of ice masses since the end of the Last Ice Age. Accelerated rises in sea level rise, called meltwater pulses, occurred three times during the EHSLR. The last one, Meltwater Pulse 1C, which peaked c. 6000 BC, produced a rise of 6.5 metres in only 140 years. It is believed that the cause was a major ice sheet collapse in Antarctica.
