Coastal and estuarine carbon removal technique may backfire when pushed too far
Researchers have discovered that ocean alkalinity enhancement, a method for carbon removal, can become counterproductive if too much alkalinity is added. Excessive calcium carbonate causes chemical instability, leading to the formation of solid particles that negate the intended carbon storage benefits.
