Cryospheric-specific climate interventions focused on sea level rise have been discussed for at least the past 40 years, but 2023 has had a significant increase in these discussions including several new research papers, two community workshops, and an AGU Town Hall event. The workshops took place in Chicago (Oct 2/3) and Stanford (Dec 9/10), and included ~60 glaciologists. Methods discussed focused mainly on ocean interventions (blocking warm water from reaching the ice sheet) and subglacial interventions (removing subglacial water or heat to slow down ice streams).
We seek broad community input on what a responsible intervention strategy would look like, how to think about the risks of intervening (or not intervening) to reduce rates of sea-level rise, and additional intervention approaches or other methods to reduce sea level rise rates beyond the necessary (but perhaps now insufficient) step of emission reduction.
