Burying the sky: Turning carbon dioxide into rock

At an Icelandic geothermal power plant, researchers are capturing carbon dioxide and burying it in basalt to keep the greenhouse gas out of the sky. But can this method be scaled up, and work elsewhere, to help meet global climate goals?

Giant icebergs spur carbon storage in Southern Ocean

A new study shows that giant icebergs floating in the Southern Ocean around Antarctica may be playing a larger role in carbon sequestration and Earth’s global carbon cycle than previously thought.

Storing CO2 in fizzy water underground

Burying carbon dioxide in underground geologic formations is an attractive option for dealing with increasing carbon dioxide in the atmosphere. But before employing such schemes, researchers need to be sure that the greenhouse gas will actually stay put. Scientists have done everything from computer modeling to pumping vast amounts of carbon dioxide into the subsurface to find out if — and how — the gas might be trapped, but gauging how sealed the formations are over geologic time scales is difficult.

Nanoscale carbon capture

Thanks to a bit of luck, the key to carbon sequestration may lie in a circular, bowl-shaped compound that draws carbon dioxide right out of the air.

Raising California's Sinking Delta

Over the past century and a half, the river delta that provides Central and Southern Californians with drinking water and farmers with productive cropland has sunk about two and a half centimeters each year. Some of the delta’s islands now lie more than six meters below sea level. Two thousand kilometers of aging levees keep them dry for now, but as the land sinks, the pressure on the levees grows. Researchers at the U.S. Geological Survey in California have uncovered a way to rebuild the delta and sequester carbon in the process.
