Understanding how carbon dissolves in water at the molecular level under extreme conditions is critical to understanding the Earth's deep carbon cycle [sciencedaily.com] -- a process that ultimately influences global climate change.
Contrary to current geochemical models, the carbon dissolved in water-rich fluid at the bottom of the Earth's upper mantle is not in the form of carbon dioxide but rather in carbonate and bicarbonate ions. That is the conclusion of scientists at UChicago's Institute for Molecular Engineering, who simulated the fate of dissolved carbon dioxide under high pressures and temperatures in the upper mantle, about 410 miles below the surface of the Earth. Their results were published in the Oct. 12 issue of Science Advances.
