A new report by scientists at Columbia University’s Earth Institute and the US Geological Survey points to an abundant supply of carbon-trapping rock in the US that could be used to help stabilize global warming.
This article mentions that there are studies about to begin around the world to use this (or volcanic basalt) to try and lock away carbon dioxide after it has been mineralized. This would remove the “leaking out” issue of gas phase sequestration. Sounds promising, but the reaction times sound very slow. A plus is that apparently appropriate minerals exist in the tailings resulting from asbestos mining, and reacting with CO2 would reduce their toxicity. Now that is a double whammy.
