Can oceans save us? Part I: Using oceans to pull more CO2 from the air
Show Notes Chapter Markers

More than 4 billion years ago, when Earth was still in its infancy, the atmosphere held more than 100,000 times the amount of CO2 it does today. Ever so slowly, that CO2 was absorbed into the oceans, where it reacted with rocks of the seafloor or was scavenged by organisms, eventually becoming trapped in sediment and slowly sequestered into Earth’s deep interior. This is the Earth’s deep-carbon cycle - nature’s way of regulating greenhouse gasses.

This week, Climate Now takes you on a special three-part podcast series that explores a novel suite of technologies, termed Ocean Carbon Dioxide Removal (CDR), that aims to speed up Earth’s natural GHG regulator by enhancing the biogeochemical processes already happening in the oceans. In our first episode, we are joined by a suite of entrepreneurs who see the climate-saving and profit-making potential of Ocean CDR, who walk us through what these technologies are, how they work, and why they could be so valuable to mitigating climate change.
