Key Findings
- 01Enhanced weathering can remove CO2 from the atmosphere by converting dissolved CO2 to bicarbonate, increasing water alkalinity and pH.
- 02Dissolution of silicate minerals releases essential nutrients (e.g., Si, P, K) that can stimulate terrestrial and marine biological productivity, further aiding carbon sequestration.
- 03The influx of alkalinity to coastal and open oceans can partially offset ocean acidification.
- 04Terrestrial carbon pools may increase due to enhanced ecosystem growth where nutrient availability is limiting.

Paragraph starter
This research investigates enhanced weathering as a geoengineering strategy, proposing that the application of finely ground minerals can sequester atmospheric CO2 and mitigate ocean acidification by increasing the alkalinity of natural waters. The dissolution of these minerals also releases nutrients that could stimulate biological productivity on land and in the ocean, potentially enhancing carbon sequestration further.
