Evidencc for an ice sheet covering Tibet during the Last Glacial Maximul;1 means a radical rethinking about glaciation in the Northern Hemisphere.The ice sheet's subtropical latitude, vast size (2.4 million km') and high elevation (-6000 m asl) caused a substantial, albedo-induced cool mg of the Earth's atmosphere and the disruption of summer monsoon circulation, The uplift of Tibet and the reaching of specific threshold values of plateau elevation being synchronous with the onset ofthe ice ages at -2.8 Ma B.P. and their intensification from -I Ma B.P. onwards, a causal link between these factors seems likely.Zusammenfassung: Der Nachweis einer hocheiszeitlichen Inlandvereisung Tibets bedeutet eine grundlegende Vernderung unserer Vorstellungen ber die nordhemisphrische Vereisung.Aufgrund ihrer subtropischen Lage, bei groer Flche (2.4 Mio km') und Hhe (-6000 m .M.) hat diese Vereisung sowohl einen groen albedo bedingten Wrmeverlust der Erdatmosphre als auch den Zusammenbruch der Sommermonsunzirkulation verursacht.
