Nature World: More than 400,000 years ago, a warming period pushed Greenland's ice sheet past its limit and raised global sea levels up to 6 meters, according to new research. The results may give us a glimpse as to what may happen as a result of Greenland's current climate-induced melting dilemma.
Known as the Marine Isotope Stage 11, this exceptionally long warming period between ice ages resulted in a global sea level rise of about 6-13 meters above present, caused by changes in the Earth's orbit around...
