Pete Convey and Mark Stevens review evidence of survival of Antarctic biota over the past tens of millions of years, implying that ice-free refugia must have existed. These studies highlight a possible mismatch between ice-sheet modeling and terrestrial evidence. The article can be found in Science at http://www.sciencemag.org/cgi/content/summary/317/5846/1877
