Since 1973 one drillhole (5-14 warm times / 6-15 glacials) and 39 expeditions in the Himalayas, Tibet, the Karakorum, the Kuen Lun, the Tienshan, the Sayan Mountains, the Altai and other parts of Central Asia contributed to detailed knowlegde about extension (2.4 Mio km2) and thickness (800-1000 m) of High Asian inland-ice. The data are best for the Last Glacial Period (Würm, Marine Isotop Stage (MIS) 4-2). The author thinks that during the last 2.75 Ma conditions that are comparable to the LGP ocurred several times in Central Asia. Geometric boundary conditions that resulted from the low latitude caused a substantial albedo-induced impact on the energy budget of the Earth during glacial times. The vast extension of the ice-sheets and the high elevation (~6000 m asl) contributed to this. A substantial albedo-induced cooling of the atmosphere is inferred.
