Abstract: Dramatically reducing emissions is the most important factor in meeting climate goals. But even in the best possible emission reduction scenarios removal of billions of tons of atmospheric carbon dioxide is likely going to be necessary to meet the international climate goal of keeping mean warming below 2 degrees. However, low-quality, reversible, and poorly quantified carbon dioxide removal will likely further erode public and academic trust in carbon trading schemes and payments. Enhanced weathering (also often called enhanced rock or mineral weathering) is a long-term (more than 1000 year) carbon dioxide removal strategy that—by using existing infrastructure—has the potential to rapidly scale. The carbon capture potential of enhanced weathering, although still poorly defined, may rival or surpass methods based on sequestration in organic carbon (e.g., afforestation or soil organic carbon storage). I will give an introduction to enhanced weathering, review key recent advances and areas of uncertainty, and end with future research directions that could unlock the potential for enhanced weathering to provide a cost-effective and robust means of carbon removal.
