Passage: Glacial melt in northern Pakistan has accelerated in recent decades, initially increasing river flow but raising long-term concerns about future water supply once the glaciers substantially shrink. Scientists also warn of glacial lake outburst floods, sudden and destructive events triggered when meltwater breaches natural ice or debris dams. Monitoring systems have been installed in several high-risk valleys to detect early warning signs. Question: What can be inferred about the future water supply from these glaciers?
A. It has already run out completely
B. It has no connection to glacier size
C. It may become uncertain once the glaciers shrink substantially ✅
D. It is guaranteed to increase forever
