"The team, including researchers from Louisiana State University and the University of Southern California, say the climate was suitable to support substantial vegetation - including stunted trees - along the edges of the frozen continent. By examining plant leaf wax remnants in sediment core samples taken from beneath the Ross Ice Shelf, the research team found summer temperatures along the Antarctic coast 15 to 20 million years ago were up to 11C warmer than today, with temperatures reaching as high as 7C. Precipitation levels also were found to be several times higher than today."
