瑞士冰川在2026年经历了创纪录水平的冰川消融，冰体体积下降5.5%，创下历史第二大跌幅57。科学家称之为"灾难性的一年"，远超过去认为的极端水平157。冰川学家过去认为单年损失2%为"极端"，但今年的损失幅度已远远突破这一阈值1。
这一加速融化的威胁远超一年的数据。过去五年间，瑞士冰川已失去近20%的总冰量2567。极端热浪和冬季降雪不足是加速融化的主要原因46。在过去12个月内，瑞士冰川在7月至9月期间释放了2.2万亿升融水1。即便在海拔3,500米的高地，科学家也发现夏末没有积雪残留1，莱茵河更在今夏某些地方达到历史低位1。
冰川融化威胁到多个关键领域的长期水资源供应。冰川监测瑞士主任Matthias Huss警告称，"这真的太灾难性了"1。他进一步表示，"在这样的条件下，阿尔卑斯冰川没有长期生存的机会"7，预计在10至15年内可能完全消失57。Huss指出，"我们现在经历的变暖100%归因于人为气候变化"57。
Switzerland's glaciers experienced a catastrophic year of melting in 2026, losing more than 5% of their remaining ice volume over the past 12 months.15 This rate of decline far exceeds what scientists previously considered extreme; glaciologists had historically regarded annual losses of 2% as exceptional, yet the current year's loss reached 5.5%, marking the second-highest on record.15 Over the past five years, Swiss glaciers have shed approximately 20% of their total mass, with a decline of 19.4% recorded between 2021 and 2026.56 The 2026 contraction was driven by record-breaking summer heat waves and insufficient winter snowfall across Europe.456
The accelerated melting poses serious threats to regional water resources. From July to September alone, Swiss glaciers released 22 trillion liters of meltwater.1 Scientists have documented the severity of conditions: at elevations above 3,500 meters, researchers found no snow remaining by the end of summer, and the Rhine River reached historic low levels in certain locations during the season.1 Matthias Huss, head of glacier monitoring for Switzerland, described the year as "truly disastrous," adding that "under these conditions, Alpine glaciers have no chance of long-term survival."57 He warned that glaciers could disappear entirely within 10 to 15 years and emphasized that "the warming we are now experiencing is 100% attributable to human-caused climate change."57
The crisis extends beyond immediate water supply concerns, as glacier melt is critical for agriculture, hydroelectric generation, and river transportation in the region.1 The rapid transformation of Alpine terrain from ice-covered landscape to barren ground underscores the accelerating pace of climate-driven environmental change in Europe, the world's fastest-warming continent.7
