In this episode, Hilary Langer met with Dr. Antonius Gagern, the Executive Director of the Carbon to Sea Initiative, for a lively conservation about a hot topic: the promises and sensitivities of tinkering with the ocean’s chemistry to enable it to store more carbon dioxide. Initial research on ocean alkalinity enhancement supports its potential as a significant means of capturing carbon. Carbon to Sea is a $50M non-profit effort that brings together leading funders and researchers to explore ocean alkalinity enhancement. The area is gaining increasing attention and traction, as evidenced by the White House’s launch of a “Fast-Track Action Committee” on Marine Carbon Dioxide Removal. Within the past year, the U.S. federal government has put out about $100 million in grants to accelerate research in the area, including $23.4M from the National Oceanic and Atmospheric Administration. Researchers and funders are balancing the urgency of action with the need to ensure that any intervention is a clear win for the oceans they seek to protect.
