New results from a drilling expedition off Antarctica may help scientists learn more about a dramatic turn in climate 34 million years ago, when the planet cooled from a “greenhouse” to an “icehouse” state. In just 400,000 years – a blink of an eye in geologic time – carbon dioxide levels dropped, temperatures plunged and ice sheets formed over what was then the lush continent of Antarctica.

JOIDES Resolution to Range from Bering Sea to Antarctic
After a major overhaul, one of the world’s two major scientific deep-sea drilling ships is back at sea. Much of the coming year’s research aboard the JOIDES Resolution will focus on sudden climate shifts...

Drilling, experiments, target huge formations off West Coast
Palisades, N.Y., July 14, 2008—A group of scientists has used deep ocean-floor drilling and experiments to show that volcanic rocks off the West Coast and elsewhere might be used to securely imprison huge amounts of globe-warming carbon dioxide captured from power plants or other sources. In particular, they say that natural chemical reactions under 78,000 square kilometers (30,000 square miles) of ocean floor off California, Oregon, Washington and British Columbia could lock in as much as 150 years of U.S. CO2 production
