Restricted impact of Holocene climate variations on the southern Greenland Ice Sheet

► Threshold lake record from Lower Nordbosø, South Greenland. ► Strong correlation with IRD record from Narsaq Sound. ► Holocene glaciation record of southern Greenland Ice Sheet. ► Limited retreat behind present ice margin during Holocene Thermal Optimum. ► Ice marginal behavior governed by temperature and topographic setting.
