Pakistan’s glaciers are changing at a pace official planning appears increasingly hard-pressed to follow. In early June, Suparco found 24 of 130 potentially dangerous glacial lakes unfrozen. By early July, the number under observation had climbed to 40. The latest assessment puts it at 105, with several lakes extending beyond their previously recorded limits. For years, glacial lake outburst floods have tended to command national attention after a road is washed away, a bridge collapses, or a village is cut off. That is too narrow a way to read what is happening. The same heat swelling these lakes is also altering the snow and glacier melt on which the Indus system depends.
That should concern far more than the people living below a moraine dam. Water from the Karakoram and western Himalaya helps sustain irrigation, hydropower, drinking supplies and industry across Pakistan. Changes in the timing and volume of meltwater will eventually be felt hundreds of kilometres downstream. A country already struggling to manage water between seasons cannot afford to treat changes in its frozen reserves as somebody else’s file.
Pakistan does have more eyes on the mountains than it once did. Suparco is watching from space, NDMA has expanded monitoring and internationally supported projects have installed early-warning systems in vulnerable valleys. Yet a Senate committee was recently told that Pakistan had 13,032 glaciers, more than 3,000 glacial lakes and 33 considered dangerous, while only 34 early-warning systems had been installed since 2017. Another 284 are still awaited. This year alone, climate-related incidents have damaged 535 houses and 31 bridges.
The more uncomfortable question came from the committee itself: how fast are Pakistan’s glaciers actually retreating? That such a basic figure is still being sought says much about the distance between satellite surveillance, field research and policymaking.
A warning from orbit is useful only if somebody below receives it in time. That requires working communications, reliable gauges, usable evacuation routes and authorities willing to stop construction where floodwater is known to travel. The technology to see the danger cannot become an excuse for failing to prepare for it.
Pakistan’s glaciers have long been treated as scenery, climate indicators or distant hazards. They are also part of the country’s water system. If their behaviour is changing, assumptions about agriculture, hydropower, storage and seasonal availability cannot remain fixed.
