Chronicles of Ice.

Quote:

A glacier is time incarnate. When we lose a glacier -- and we are losing most of them -- we lose history, an eye into the past; we lose stories of how living beings evolved, how weather vacillated, why plants and animals died. The retreat and disappearance of glaciers -- there are only 160,000 left -- means we're burning libraries and damaging the planet, possibly beyond repair. Bit by bit, glacier by glacier, rib by rib, we're living the Fall.
