Question

[111]. Passage: Himalayan glaciers feed rivers on which millions depend, yet they are retreating in most monitored basins. Warming shortens snowfall seasons, dark dust and soot accelerate melting, and new lakes form behind unstable moraines that can burst without warning. The danger is not a single flood but a changing regime: less reliable dry-season flow, more sudden hazards, and greater uncertainty for farming and hydropower. Adaptation requires local monitoring, early warning for glacial lakes, and water-sharing arrangements that can cope with variability rather than assuming a fixed average flow. According to the passage, which statement is true?

1.
