[Live Science] 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.
