Past Climate In Antarctica: Looking Back to Our Future

Carbon dioxide levels are predicted to rise during this century to levels not seen in 25 to 50 million years. Back during this time, the Earth changed from a generally ice-free 'greenhouse world' to a more much colder and heavily glaciated 'icehouse world'. Dr. Pekar will provide an overview of Antarctic climate changes when CO2 levels were similar to what is predicted for this century and also provide some of early results from IODP Wilkes Land Expedition.
