Novel Marine-Climate Interventions

Description

Understanding the Current Global Status of Their Use and How We Can Govern Them Responsibly

Oct 15, 2025 10:00 PM EST

Novel marine-climate interventions – such as ocean fertilization, assisted evolution of marine species, assisted migration of marine species, regrowing targeted species, restoring habitat, and aquaculture for carbon sequestration – are being rapidly implemented to address both the causes and consequences of warming oceans. A recent survey revealed five types and 17 sub-types of interventions proposed or deployed in 37 marine systems globally. The climate benefits of these interventions are uncertain, however, and there is limited assessment of the broader ecological, cultural and social risks and benefits. This webinar will present the types of novel interventions being developed or deployed, how these interventions are being designed, their geographic distribution and stage of development, types of climate goals and benefits pursued, and current arrangements (if any) for responsible governance. Recommendations for responsibly governing these interventions – such as bioethical assessments, requiring assessments at pilot scales, developing monitoring processes, and building in triggers for downscaling or ceasing activities – will also be discussed.
