Glaciers on the Third Pole are extensively retreating

Spatial pattern of glacial retreat
Amplitude of glacial retreat in the marginal regions is larger than those inside the interior regions
Glacial area retreated by 7% in the 40a before 2000, and by 5% in the past 10a
Glacial retreat in the past 10a is accelerating.

三、研究区划分
Only on the Tibetan Plateau, there are more than 1000 lakes, most are supplied by glacial melting water; there are more than 3000 glacial terminus lakes which are directly at glacial terminus
