Himalayan ice caps melting fast


Ice cores drilled last year from the summit of a Himalayan ice field lack the distinctive radioactive signals that mark virtually every other ice core retrieved worldwide.

The radioactivity from nuclear tests in the 50’s and 60’s is not present in some Himalayan ice caps. This means that ice formed from that time on has already melted, a bad omen for the half billion people in the area who depend on water from rivers filled with meltwater.
