Mountain glaciers of NE Asia in the near future: a projection based on climate-glacier systems' interaction
International audience In this study we consider contrasting continental (Orulgan, Suntar-Khayata and Chersky ranges located in the Pole of Cold area at the contact of Atlantic and Pacific influences) and maritime (Kamchatka under the Pacific influence) Russian glacier systems. Our purpose is to pre...
