From June 29 onward, every additional liter of meltwater flowing from Switzerland’s glaciers comes at the direct expense of the ice itself, marking this year’s Glacier Loss Day. The milestone arrives after low snow cover, Saharan dust, and an intense heat wave accelerated melting, while researchers warn that shrinking glaciers could eventually reduce the very meltwater many river systems depend on during hot, dry summers.

从6月29日起，瑞士冰川流出的每一升融水都直接以冰层本身的代价为代价，标志着今年的冰川流失日。这一里程碑是在积雪稀少、撒哈拉尘埃和强烈热浪加速融化之后到来的，研究人员警告说，冰川的缩小最终可能减少许多河流系统在炎热干燥夏季依赖的融水。

Switzerland’s glaciers have reached a critical seasonal turning point earlier than many would hope. Beginning June 29, the country’s glaciers no longer have enough remaining snow to offset ongoing melting. From this day forward, every warm day strips away glacier ice, permanently reducing their overall mass.

瑞士的冰川比许多人预期的更早达到了一个关键的季节转折点。从6月29日起，该国冰川的剩余积雪已不足以抵消持续的融化。从今天起，每个温暖的日子都会剥离冰川冰层，永久减少其整体质量。

The milestone, known as Glacier Loss Day, highlights how quickly the country’s glaciers are responding to an exceptionally challenging year. Low snow accumulation, dust carried from the Sahara, and a powerful heat wave have combined to push glacier melting into overdrive.

这一里程碑被称为冰川流失日，凸显了该国冰川对这一极具挑战性的一年的迅速响应。低积雪、撒哈拉带来的尘埃以及强烈的热浪共同推动了冰川融化的加速。
