New paper: Differentiating solar radiation modification experiments

The paper, led by Ben Redmond Roche, explores the full spectrum of plausible SRM field experiments and how different types of experiments may interact with existing governance and regulatory frameworks.

"As attention to SRM grows," says co-author Dante McGrath, "it’s valuable to see these discussions developed into a peer‑reviewed analysis that challenges the simple small‑/large‑scale binary in governing field experiments."

Dante is a Research Associate at the Centre for Climate Repair at the University of Cambridge. "I’m grateful to have contributed to this study and to the related Co-CREATE workshops at UCL and the 2025 Degrees Global Forum."
