A paper published in 2008 by a group of researchers at the University of Wisconsin lead by Anders Carlson used the deglaciation of North America at 9000 years before present as an analogue to predict sea level rise of 1.3 meters in the next century<ref>{{cite web|url=http://www.newscientist.com/article/dn14634-sea-level-rises-could-far-exceed-ipcc-estimates.html|title=Sea level rises could far exceed IPCC estimates|accessdate=2009-01-24|publisher=New Scientist}}</ref><ref>{{cite journal|doi=10.1038/ngeo285|title=Rapid early Holocene deglaciation of the Laurentide ice sheet|year=2008|author=Carlson, Anders E.|journal=Nature Geoscience|volume=1|pages=620|first2=Allegra N.|first3=Delia W.|first4=Rosemarie E.|first5=Gavin A.|first6=Faron S.|first7=Joseph M.|first8=Elizabeth A.}}</ref>, which is also much higher than the IPCC predictions. However, models of glacial flow in the smaller present-day ice sheets show that a probable maximum value for sea level rise in the next century is 80 centimeters, based on limitations on how quickly ice can flow below the [[equilibrium line altitude]] and to the sea.<ref>{{cite journal|doi=10.1126/science.1159099|year=2008|month=September|author=Pfeffer, Wt; Harper, Jt; O'Neel, S|title=Kinematic constraints on glacier contributions to 21st-century sea-level rise.|volume=321|issue=5894|pages=1340–3|issn=0036-8075|pmid=18772435|journal=Science (New York, N.Y.)}}</ref>
