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 ...

Weathering of huge amounts of tiny rocks could be a means to reduce the greenhouse gases in the atmosphere. While this is normally a slow natural process during which minerals chemically bind CO2, ...

A weird technology has emerged as a leader in the quest for net zero. But this form of carbon capture, called Enhanced Rock Weathering (or ERW for short), still requires innovation — and government ...

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 ...

As humanity continues the arduous task of weaning itself off fossil fuels, there has been an increased onus on the development of carbon removal technologies. Unlike capture and storage, these aim to ...

For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such ...

Rocks, particularly the types created by volcanic activity, play a critical role in keeping Earth’s long-term climate stable and cycling carbon dioxide between land, oceans, and the atmosphere. In ...

On a banana plantation in rural Australia, a second-generation farming family spreads crushed volcanic rock between rows of ripening fruit. Eight thousand kilometers away, two young men in central ...

image: During the Ordovician period, the concentration of CO2 in the earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the ...

Reactions between rocks, rain and carbon dioxide in the atmosphere have helped to stabilise the climate throughout Earth’s history, but they won’t prevent our carbon emissions from causing severe ...
