Plan Sea: Ocean Interventions to Address Climate Change
“Plan Sea” focuses on ocean-based climate solutions that seek to remove carbon dioxide from the atmosphere (carbon dioxide removal) or reduce incoming solar radiation (solar radiation modification). The podcast scrutinizes risks and benefits of these options, as well as matters of governance, stakeholder engagement, ethics, and politics.
