Calcium carbonate is the largest reservoir of carbon on the planet. It is found in rocks the world over, shells of both land- and water-dwelling creatures, and pearls, coral, marble and limestone.

What links sea urchins, limestone and climate change? The common thread is calcium carbonate, one of the most widespread minerals on Earth. UC Davis researchers have now measured the energy changes ...

A soil-dwelling microbe has shown a surprising ability to trap carbon dioxide and turn it into rock. Scientists have discovered ... atmospheric pressure—Bacillus megaterium formed calcium carbonate ...

The team of Kenyan, U.S., Austrian, and Swiss scientists found that the trees could draw carbon dioxide (CO2) from the atmosphere and store it as calcium carbonate ‘rocks’ in the surrounding soil.

Planting trees has long been touted as a major tool in the fight against climate change. And on the surface, that makes a lot ...

Calcium carbonate, or CaCO3, comprises more than 4% of the earth's crust. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small ...
