"Farmland's Rock Solid Solution: Harnessing Rocks to Combat Global Warming"
Scientists from UC Davis and Cornell University have conducted a field study demonstrating that applying crushed volcanic rock to croplands can store carbon in soil, even in dry climates like California. This "enhanced rock weathering" technique could potentially capture up to 215 billion tons of CO2 over 75 years if implemented globally. The study found that the addition of crushed rock stored carbon dioxide in the soil, even during an extreme drought. This research suggests that drylands, which cover a significant portion of Earth's land surface and are expanding due to climate change, could play a crucial role in carbon storage efforts.
