UnverifiedIn Alaska and elsewhere, ground subsidence and building damage caused by permafrost thaw have already occurred.69% similarUnverifiedClimate change is shortening winters in the subarctic region and changing snow conditions, breaking the original pattern of predation pressure.67% similarUnverifiedFreeze-thaw cycles are a key mechanism of instability in high-mountain rock masses: meltwater seeps into fissures during the day, freezes and expands at night, and repeated action causes fissures to expand and rock mass strength to decline.64% similarUnverifiedThe stability of the Arctic permafrost carbon pool is crucial to the global climate, and wildfires not only produce direct emissions but also disturb permafrost structure.64% similarUnverifiedDuring China's 2008 southern ice disaster, insulator flashover caused by the combination of widespread icing and contamination was one of the important factors leading to large-scale power grid paralysis.63% similar
