注意到过去几十年来，全球变暖导致冰冻圈大范围缩小、冰盖和冰川大量流失、积雪减少，进而导致高山地区稳定性降低，改变了以积雪为主和靠冰川补给的河流流域的径流和水资源的数量和季节性，并导致一些高山地区的农业产量局部下降、缺水包括下游可用水资源减少以及全球平均海平面上升，
Noting that, over the past decades, global warming has led to widespread shrinking of the cryosphere, with mass loss from ice sheets and glaciers and reductions in snow cover, which have decreased the stability of high mount ain areas and changed the amount and seasonality of run-off and water resources in snow-dominated and glacier-fed river basins, as well as contributed to localized declines in agricultural yields in some high mountain regions, water scarcity, including red uced downstream water availability, and increased global mean sea level,
