In this episode, I talk with climate scientist Zeke Hausfather about how enhanced rock weathering (ERW) turbocharges a natural process to permanently store CO₂. We dig into how it profits from existing infrastructure, and the big questions around measuring and verifying the carbon captured. Zeke also explains why farmers might actually benefit from spreading all those rocks — and why ERW could become a key, if limited, piece of the broader climate puzzle. This is a public episode.
