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 about why this work mattersThis conversation reminded me of my favourite moment in a meal — a perfectly cooked soup — and how the ocean, like that, is part of life itself. Balanced, nourishing, alive.Recorded ahead of NY Climate Week, with shout-outs to Grace Andrews, Hourglass Climate, [C]Worthy, and Dr. Alicia K. for hosting and driving the ocean CDR conversation. Cheering you all from afar 💚▶️ Watch the full episode on YouTube: https://www.youtube.com/watch?v=lWk-fagdkKk#OceanCDR #Alkalinity #ClimateTech #MakeClimateCoolAgain
