Safeguarding the polar regions from dangerous geoengineering: a critical assessment of proposed and future prospects

### Geoengineering: solutions or distractions to the climate crisis? This session explores the technical feasibility, long-term costs, environmental risks, and governance limitations of five approaches. Examine the scientific and policy challenges of deploying polar geoengineering tools as a climate mitigation strategy. Hear from the authors of a [Frontiers in Science lead article](https://www.frontiersin.org/journals/science/articles/10.3389/fsci.2025.1527393/full)—including a representative of the Intergovernmental Panel on Climate Change (IPCC)—as they analyze five polar geoengineering proposals: aerosol injection, sea walls, ice albedo modification, basal water removal, and ocean fertilization. The researchers will outline their conclusions that these proposed interventions would harm the fragile polar ecosystems they intend to protect, and how the proposals fail to meet core scientific and policy criteria. Our expert panel will also discuss how these initiatives may detract from achieving Net Zero, by diverting time, funding, and attention from efforts toward achieving deep decarbonization.
