Shrinking glaciers: A chronology of climate change (w/ Video)

During the last ice age, glaciers dominated New Zealand’s Southern Alps until warming temperatures some 20,000 years ago sent them into retreat. Scientists at Lamont-Doherty Earth Observatory, with their colleagues, are investigating the rocky remnants these glaciers left behind to learn precisely when the ice withdrew, and what glacier retreats globally can tell us about the climate system.
