Sea Level Rise Less from Greenland, More from Antarctica, Than Expected During Last Interglacial

ScienceDaily (July 29, 2011) — During the last prolonged warm spell on Earth, the oceans were at least four meters -- and possibly as much as 6.5 meters, or about 20 feet -- higher than they are now. Where did all that extra water come from? Mainly from melting ice sheets on Greenland and Antarctica, and many scientists, including University of Wisconsin-Madison geoscience assistant professor Anders Carlson, have expected that Greenland was the main culprit.
But Carlson's new results, published July 29 in Science, are challenging that assertion, revealing surprising patterns of melting during the last interglacial period that suggest that Greenland's ice may be more stable -- and Antarctica's less stable -- than many thought.
