Projects that spray rock dust on farms remove more carbon dioxide from the atmosphere than competing technologies, but carbon removal efforts are not reaching the amount needed to avoid dangerous levels of global warming. is not far behind.
This method, known as enhanced rock weathering, involves spreading crushed volcanic rock in a field to encourage the natural weathering process that converts atmospheric CO2 into stable mineral forms. Driven by its relative simplicity and emerging evidence that rock dust can not only sequester carbon but also improve crop yields, this…
