You can read here my Editorial commenting on the Frontiers in Science Lead Article, published on 9 September 2025, a review by Martin Siegert and colleagues, ‘Safeguarding the polar regions from dangerous geoengineering: a critical assessment of proposed concepts and future prospects‘

My three key points:

• There is a very checkered history of previous attempts at deliberate climate control beyond very small local scales.
• More research into climate intervention technologies cannot resolve the cultural, ethical, and political challenges complicating decisions around their deployment.
• Decisions on whether to research or deploy polar geoengineering technologies must account for the rights of Arctic dwellers, while also considering broader global interests.
