The glacial environments on the Tibetan Plateau and the mechanisms for glacier and snow accumulation are discussed on the basis of new evidence of global temperature fluctuations and regional biome type changes. The biome types show that extensive snow and glacier fields could develop on the Tibetan Plateau with a temperature lowering of 7–9°C and precipitation decrease by 30–70 % . Considering the cooling effect due to an increase of albedo resulting from increased snow and ice coverage, it is possible that the valley glaciers became enlarged to form large glaciers and snow fields during the Last Glacial Maximum. This new environmental modeling shows that the environmental conditions changed considerably during past glaciations. Such changes might have notable impacts on the monsoons and possibly on global climate.
