A relief-specific model of the ice age on the basis of uplift-controlled glacier areas in Tibet and the corresponding albedo increase as well as their positive climatological feedback by means of the global radiation geometry
ABSTRACT: The onset of the ice age era at ~2.75 Ma BP and its increasing intensity from ~1 Ma BP onwards cannot be explained by variations of the Earth¹s orbit. Evidence supporting a 2.4 million km2 ice sheet on the Tibetan plateau during the Last Glacial Maximum has led to the hypothesis that the resulting albedo-induced heat loss in the Earth¹s atmosphere may have triggered global ice ages. Recent data obtained from marine and terrestrial sediment records now confirm the climatic-ecological impact of a Tibetan glaciation; they also show that the development of Tibet¹s ice sheet was synchronous with the onset and intensification of global ice ages.
