The Siachen Glacier is the world's largest non-polar glacier. It is 43 miles long, and covers about 270 square miles (including its tributaries). Its heights are occupied by India, but it is claimed by Pakistan to be in their area of Kashmir.
The Siachen glacier has been at the heart of the long-running Kashmir border conflict between these two rivals. There was an excellent story from four years ago in Time Magazine, "War at the Top of the World" that detailed the conflict.

This is certainly an area that merits further study, and if these environmental concerns can help bring about a demilitarization of the volatile border, then some good could come out of this. On the other hand, I do wonder whether this was simply another example of a Pakistani officials going out of their way to antagonize India over Kashmir, as they have been threatening war over water.
