UC Davis researchers find adding crushed volcanic rock to farmlands can remove carbon dioxide from the air. This 'enhanced' rock weathering works even in dry climates. (Amy Quinton/UC Davis) Adding ...

Carbon dioxide (CO₂) is naturally removed from the air when it reacts with certain types of rock. We can accelerate this process by crushing suitable rocks and spreading them over agricultural fields.

Adding crushed volcanic rock to farmland can pull carbon dioxide out of the air. In a field test, scientists found that the process works even in dry climates. Adding crushed volcanic rock to cropland ...

Adding crushed volcanic rock to cropland could play a key role in removing carbon from the air. In a field study, scientists at the University of California, Davis, and Cornell University found the ...
