Five well-publicized polar geoengineering ideas are highly unlikely to help the polar regions and could harm ecosystems, communities, international relations, and our chances of reaching net zero by 2050, according to a Frontiers in Science lead article .
Join the authors of the article— Prof Martin Siegert , Dr Valérie Masson-Delmotte , and Prof Steven Chown —at this virtual event as they analyze the most developed geoengineering proposals being considered for use as a climate mitigation strategy in Antarctica and the Arctic.
The authors and fellow experts will explore the following 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.
This free webinar takes place tomorrow, 24 September 2025, 11:00-12:30 CEST .
