Ice sheet collapse linked to megaflood

Dramatic warming at the end of the last ice age produced an intense rise in sea level and a massive ice sheet collapse in the Antarctic.

The sea level rise is known as Melt-Water Pulse 1A, and new research indicates it increased sea level by about 45 feet (14 meters) sometime between 14,650 and 14,310 years ago, during the same time as a period of rapid climate change known as the Bølling warming.

Understanding the impacts of earlier warming and sea-level rise is important for predicting the effects of future warming....
