Rodrigo Riera What if we could engineer the ocean to absorb more carbon dioxide? What if we could cool the planet, not with emissions cuts alone, but by enhancing the ocean’s natural carbon cycle?

From ocean alkalinity enhancement and iron fertilization to artificial upwelling, ocean geoengineering ideas are growing louder in scientific circles—and raising serious questions in ethical and policy debates.

Today, we’ll unpack the science, explore the risks, and ask: Is this humanity’s Plan B—or a Pandora’s box?

Ocean Rewilding: Reversing the Clock on Climate Change Ep. 3. Ocean Rewilding: Reversing the Clock on Climate Change Rodrigo Riera You might’ve heard of rewilding on land—bringing back wolves to Yellowstone, or letting forests regenerate. But beneath the surface, a similar revolution is happening.

From oyster reefs and kelp forests to coral restoration and even the return of whales, ocean rewilding is about restoring ecosystems that not only support life—but also help store carbon.

Today, we’re going to explore how restoring marine biodiversity creates more resilient, more effective carbon sinks—and how people around the world, from scientists to fishers to Indigenous communities, are leading the charge.

Seaweed to the Rescue: Farming Our Way Out of Emissions Ep. 2. Seaweed to the Rescue: Farming Our Way Out of Emissions Rodrigo Riera Yes—seaweed. The stuff that wraps your sushi or washes up on the beach. But beneath its humble surface, seaweed holds incredible promise. It grows without fresh water, fertilizer, or land. It absorbs carbon dioxide, restores ocean ecosystems, and is being reimagined as everything from biofuel to bioplastic.

In this episode, we’re diving into the world of seaweed farming—and how it could help us cut emissions, clean our seas, and create sustainable products for a rapidly changing world.

Blue Carbon: The Ocean’s Hidden Climate Ally Ep. 1. Blue Carbon: The Ocean’s Hidden Climate Ally 1 Rodrigo Riera Carbon dioxide (CO₂) is one of the most significant greenhouse gases driving climate change. When released into the atmosphere—primarily through the burning of fossil fuels and deforestation—it traps heat, leading to global warming and widespread climate disruptions like rising sea levels, extreme weather, and ocean acidification. Storing CO₂, therefore, is crucial to slowing these effects and stabilizing our climate
