Disappearing Ice Caps - Giff Miller on Baffin Island

Giff Miller, geologist and paleoclimatologist, walks the margins of melting glaciers on rugged Baffin Island, Nunavut, Canada. He and his team are looking for dead plants emerging from the ice. Buried since the beginning of the last ice age, they hold direct evidence of past climates. Film by Matthew Kennedy of Earth Vision Trust.
