Ocean Soup Explained: How Alkalinity Draws Down CO₂ (Grace Andrews | Hourglass Climate)

In this episode of Bite-Size Climate Tech, I sit down with Dr. Grace Andrews to explore Ocean Soup — the idea that adding minerals to the ocean is like adding ingredients to a recipe. Done right, it raises alkalinity, pulls CO₂ from the air back into the sea, and keeps our climate in balance. Done wrong… it’s like adding too much salt.
Grace explains:

• 🌊 Ocean alkalinity enhancement and “the recipe” for safe CO₂ removal

• 🧪 Why measuring alkalinity and trace elements matters (MRV & EMRV)

• 🥄 How even hard science can feel relatable when explained through cooking

• 🌱 A sentence of hope…
