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 ...

New research has overturned the traditional view that natural rock weathering acts as a carbon sink that removes CO2 from the atmosphere. Instead, this can also act as a large CO2 source, rivaling ...

What if cropdusting could cool down the climate? What about rockdusting? Turns out sprinkling rock dust on fields may enhance a process called rock weathering, capable of trapping and removing ...

From sugar plantations in Brazil to tea estates in India, crushed rock is being sprinkled across large stretches of farmland globally in a novel bid to combat climate change. The technique is called ...

A tractor drives across a grassy field, facing the camera, between rows of wire trellises over plants pruned close to the ground. Clouds of finely ground rock spray out on either side. As part of the ...

Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of ...
