The cryosphere is an important component of the global climate system. Cryospheric components are sensitive to climate warming, and changes in the cryosphere can lead to serious hazards to human society, while the comprehensive understanding of cryospheric hazards largely remains unknown. Here we summarized the hazards related to atmospheric, oceanic and land cryosphere. The different types of cryospheric hazards, including their phenomena, mechanisms and impacts were reviewed. Our results suggested that: 1) The recorded hazards from atmospheric cryosphere including frost, hail, freezing rain decreased or showed great spatial heterogeneities, while their future changes are difficult to predict, and the extreme cold events in winter may increase in the future; 2) Sea ice extent declines rapidly, and iceberg numbers will increase. The permafrost-dominated coastline erosion will be exacerbated by climate warming. Meanwhile, the sea level rise is expected to continue in the next decades; 3) The glacier collapse, glacial lake outbursts and paraglacial readjustments will increase in the future. Although the total area of snow cover will decrease, the heavy snow events, snow avalanches, and snowmelt floods will not decrease simultaneously. The permafrost-related rock and debris flow and thaw slump will also increase with permafrost degradation. Taken together, we concluded the cryosphere is shrinking, while cryospheric hazards will likely increase in a warming climate.

冰冻圈是全球气候系统的重要组成部分。冰冻圈的组成部分对气候变暖很敏感，冰冻圈的变化会导致对人类社会的严重危害，而对冰冻圈危害的全面了解在很大程度上仍然未知。在这里，我们总结了与大气，海洋和陆地冰冻圈有关的危害。审查了不同类型的冰冻圈危害，包括其现象，机理和影响。我们的结果表明：1）记录的来自大气冰冻圈的灾害包括霜冻，冰雹，冻雨减少或显示出很大的空间异质性，而它们的未来变化难以预测，并且冬季的极端寒冷事件将来可能会增加；2）海冰面积迅速下降，冰山数量将增加。气候变暖将加剧以多年冻土为主的海岸线侵蚀。同时，预计海平面将在未来几十年内继续上升；3）将来冰川崩塌，冰川湖爆发和冰川副调整将增加。尽管积雪的总面积将减少，但大雪事件，雪崩和融雪洪水不会同时减少。与多年冻土有关的岩石和泥石流以及解冻坍落度也将随着多年冻土的退化而增加。综上所述，我们得出的结论是冰冻圈正在缩小，而冰冻圈的危害可能会在气候变暖时增加。冰川湖的爆发和冰川副调整将在未来增加。尽管积雪的总面积将减少，但大雪事件，雪崩和融雪洪水不会同时减少。与多年冻土有关的岩石和泥石流以及解冻坍落度也将随着多年冻土的退化而增加。综上所述，我们得出的结论是冰冻圈正在缩小，而冰冻圈的危害可能会在气候变暖时增加。冰川湖的爆发和冰川副调整将在未来增加。尽管积雪的总面积将减少，但大雪事件，雪崩和融雪洪水不会同时减少。与多年冻土有关的岩石和泥石流以及解冻坍落度也将随着多年冻土的退化而增加。综上所述，我们得出的结论是冰冻圈正在缩小，而冰冻圈的危害可能会在气候变暖时增加。
