Theme 1 – Earth System Science Modelling

Our Theme 1 programme is being developed across the following three strategic areas to address high-level questions concerning the capacity of rock weathering driven by intensively managed crops to capture carbon and ultimately affect future CO2-climate trajectories, ocean-atmosphere chemistry and marine ecosystems.

Theme 2 – Fundamental Crop Weathering Science

Our Theme 2 programme is utilising world-class controlled environment facilities in Sheffield to elucidate mechanisms and genetic controls on weathering by major warm climate crops (maize and rice) to accelerate the development of new faster weathering varieties that maximise carbon capture and protection against pests and diseases, thus reducing pesticide usage and costs.

Theme 3 – Applied Weathering Science

Our Theme 3 programme is undertaking large-scale field trials to address questions concerning rates of rock weathering in agricultural soils under natural conditions and how feedbacks, e.g., via nutrient release and pH change, may increase food/bioenergy crop productivity and slow soil greenhouse gas emissions.

Theme 4 – Sustainability & Society

Our Theme 4 programme is addressing the real-world feasibility of enhanced weathering through integrated assessment modelling of its environmental and socio-economic impacts, assessment of a global sustainable supply chain capable of carbon capture and storage, and developing a responsible research and innovation framework.

Pop-Up University: Solving Earth’s climate emergency by farming with rocks!

Sep 15, 2021

Join Amy Lewis and researchers from the Leverhulme Centre for Climate Change Mitigation, based in the Faculty of Science for a series of live experiments showing how rock dissolution (weathering) can help remove carbon dioxide from the atmosphere. Rock dissolution occurs naturally when rocks interact with water and this is important to help slow climate change.

Meet the researchers who are working to speed up rock weathering – see live experiments and view rocks under the microscope.

Can rock dust be a climate fix for agriculture?

Sep 2, 2021

Scientists are dusting crop fields with pulverized rocks to supercharge the chemical process that grabs carbon from the air and sequesters it in the soil. All while increasing crop yields.

Leverhulme Centre for Climate Change Mitigation director, David Beerling, who is five years into a decade-long effort to investigate enhanced weathering on croplands, published a paper in Nature that demonstrated the potential of the method. He and colleagues found that if China, India, and the United States applied rock dust to all of their agricultural lands, 1 billion tons of carbon dioxide could be removed from the atmosphere.
