Idly mentally running through mental future scenarios, as I always am, hit on an interesting one, it’s probably good enough for a paperback novel (really, a Bollywood movie) but anyone with actual knowledge chip in to say how far off I am:

as global warming continues, some year the Himalayas have a heat wave which appreciably shrinks mountaintop glaciers. The weight of the ice had been calculated into the tectonic stasis of the underlying Eurasian-Indian plate convergence fault, and its removal provokes many quakes. Combined with mountain slopes inundated with meltwater, a series of massive, apocalyptic mudslides push into the Gangetic Plain. Though they don’t reach the Ganges river itself, the already hugely swollen Ghaghara, a Ganges tributary, clouds with soil; the combined high flow and sediment deposition where the river slows result in the river radically changing course. Effects downstream (heh) of this cause massive disruption in Bangladesh, the state collapses, and anarchy rules, the resulting instability is then somehow exported next door to India.

Thoughts?
