Scientists are spreading crushed volcanic rock across farmland; here's how ordinary farms could help remove carbon dioxide from the atmosphere

• Rock weathering for carbon dioxide removal (Illustration)/ Image Credit: CanvaAs countries race to cut greenhouse gas emissions, scientists are exploring innovative ways to remove carbon dioxide (CO₂) that is already in the atmosphere.
• One approach attracting growing attention involves something surprisingly simple: spreading finely crushed volcanic rock over farmland.
• The method, known as enhanced rock weathering (ERW), speeds up a natural geological process that has helped regulate Earth's climate for millions of years.
