Scientists probe underground depths of Earth's carbon cycle

Scientists probe underground depths of Earth's carbon cycle Chicago IL (SPX) Nov 14, 2016 - Understanding how carbon dissolves in water at the molecular level under extreme conditions is critical to understanding the Earth's deep carbon cycle--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 an ... more
