Turning CO2 into Stone

The CarbFix Project in Iceland
Yes
Professor of Environmental Science, Barnard College

The success of carbon capture and storage (CCS) depends on the ability to safely and permanently store CO2. For the first time, scientists working with a power plant in Iceland have demonstrated a way to pump CO2 into basalt rocks and turn it from gas to an environmentally benign carbonate mineral. Over 95 percent of the CO2 injected into the CarbFix site in Iceland was turned to a solid in less than 2 years, the scientists report in a recent study. This result contrasts with the common view that the immobilization of CO2 as carbonate minerals within geologic reservoirs takes several hundreds to thousands of years. The results demonstrate that the safe long-term storage of anthropogenic CO2 emissions through mineralization can be far faster than previously postulated.

Ancient Shells Hold Clues to Life in a Warmer World

Yes

The sea floor holds evidence of how the oceans changed over millions of years and how sea life struggled and survived in the elements. Bärbel Hönisch, a biologist and oceanographer at Columbia University's Lamont-Doherty Earth Observatory, explains how scientists use the chemistry in ancient shells and the behavior of modern ocean microbes to figure out how the ocean environment changed in the past, how sea life responded, and what that can tell us about the future.
