The potential impact of the uncertainty on final estimates of net carbon removal or storage duration: negligible, low, medium, high, or very high.
The formation of solid carbonates decreases CO₂ drawdown relative to the aqueous reactions that result in alkalinity run-off. It therefore must be considered if drawdown is being estimated on the basis of direct observation of mineral weathering rather than via estimation of alkalinity run-off. Terrestrial carbonate precipitation depends on the type of primary mineral dissolving, carbonate saturation state, and other local environmental conditions.
Second release. Changed name from 'Surficial carbonate precipitation' to 'Terrestrial carbonate precipitation' for clarity and edited component text to reflect the name change. These edits occured as part of a broader update to the Enhanced Weathering pathway.
