Tibetan Plateau Permafrost Gaining Ice Despite Warming

A study led by Li Dongfeng at Peking University reveals that over one-third of the Qinghai-Xizang Plateau's permafrost has gained ice since 2000. Despite regional warming occurring twice as fast as the global average, increased precipitation is driving this trend.

Stronger westerly winds have boosted annual rain and snowfall by 60% in the interior plateau. This extra water seeps into the ground during summer and refreezes in the subzero soil, effectively outweighing the effects of rising temperatures. Researchers suggest these findings should inform infrastructure planning and climate adaptation policies, as ground ice shifts could impact roads and bridges.
