Arctic geoengineering - Duffey

Arctic geoengineering - Duffey

Alistair Duffey picks up the baton from Madelyn Hotaling's previous episode. He gives further comparison of several polar geoengineering technologies: SAI, MCB, CCT, and microspheres. Does any approach offer us a reliable and safe way to target the Arctic? Paper discussed Solar Geoengineering in the Polar Regions: A Review Alistair Duffey, Peter Irvine, Michel Tsamados, Julienne Stroeve First published: 31 May 2023 https://doi.org/10.1029/2023EF003679 Additional paper mentioned Mixed-phase regime cloud thinning could help restore sea ice Citation D Villanueva et al 2022 Environ. Res. Lett. 17 114057 DOI 10.1088/1748-9326/aca16d
