Scientists think they have found a smart way to constrain carbon dioxide emissions - just turn them to stone.

The researchers report an experiment in Iceland where they have pumped CO2 and water underground into volcanic rock.

Reactions with the minerals in the deep basalts convert the carbon dioxide to a stable, immobile chalky solid.

Last month, the journal Science published a special issue examining the challenges and opportunities of an urbanizing world. Titled “Urban Planet” and featuring an image of clouds wafting across skyscrapers in Dubai, the issue opened with an eye-catching statistic: “More than half of the world’s people now live in cities.”

Interestingly, the city, which is partnering with Hitachi on the project, also wants to incorporate others’ data. — Network World
