Achieving the Paris Agreement’s goal of limiting the increase in global average temperatures well below 2°C, and ideally to 1.5°C, above pre-industrial levels will likely require the removal of carbon dioxide from the atmosphere. This could be achieved in various ways, including by enhancing natural weathering processes in which carbon dioxide reacts with silicate-based rocks, eventually forming carbonate minerals (e.g., limestone). Research suggests that the amount of carbon dioxide sequestered through this natural process can be increased by grinding silicate-rich minerals (e.g., olivine) or rocks (e.g., dunite) to increase their surface area and then spreading the powder over land or …

Despite scientists’ dire warnings about the catastrophic impacts of climate change, the greenhouse gases that cause it continue to be emitted in substantial amounts. While there is no question that deep, across the board cuts in greenhouse gas emissions are essential, many scientists now agree that simply cutting future emissions will not be enough. It will also be necessary to remove previously-emitted greenhouse gases from the atmosphere. This paper explores one greenhouse gas removal technique – enhanced weathering – which involves spreading finely ground silicate rocks or other materials with similar chemical composition over land or ocean waters. The materials …
