A report in the journal Nature has revealed that enhanced rock weathering (ERW) could help slow climate change by sucking carbon dioxide from the atmosphere. This process involves spreading rock dust on farmland to help absorb atmospheric carbon dioxide. When rocks, such as basalt and other silicates, are crushed and added to the soil, they dissolve and react with carbon dioxide, forming carbonates and lock carbon dioxide. Although this is the first time that scientists are proposing this approach in dealing with carbon dioxide, it is not a new concept.
