Discovering ancient climates in oceans and ice: Rob Dunbar on TED.com

Posted by: Tedstaff

Rob Dunbar hunts for data on our climate from 12,000 years ago, finding clues inside ancient seabeds and corals and inside ice sheets. His work is vital in setting baselines for fixing our current climate — and in tracking the rise of deadly ocean acidification. (Recorded on Mission Blue Voyage, April 2010 in the Galapagos Islands, Ecuador. Duration: 18:15)
