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.
