More Moore - polar SRM research

John Moore joins the podcast to discuss his recent Viewpoint article responding to Siegert et al.’s paper on polar geoengineering. While Siegert and colleagues argue that proposed interventions are infeasible, environmentally dangerous, and a distraction from decarbonization, Moore contrasts the prevailing “consequences-based paradigm” (raising alarms to spur actions) with a new “compassionate harm reduction paradigm” that calls for exploring all potential tools including geoengineering rather than rejecting them outright, so humanity has options to reduce harm if warming overshoots.


The conversation covers the risks of melting glaciers and sea-level rise, and specific concepts such as stratospheric aerosol injection. Moore also stresses the importance of Arctic Indigenous leadership, pointing to Saami Council-led review processes as a model for rights-based and knowledge co-produced governance.


The discussion also highlights the sharp divides in the climate community over polar geoengineering and raises fundamental questions about the responsibilities of scientists in an era of accelerating climate risk.
