Substantial Climate Response outside the Target Area in an Idealized Experiment of Regional Radiation Management
Radiation management (RM) has been proposed as a conceivable climate engineering (CE) intervention to mitigate global warming. In this study, we used a coupled climate model (MPI-ESM) with a very idealized setup to investigate the efficacy and risks of CE at a local scale in space and time (regional radiation management, RRM) assuming that cloud modification is technically possible.

Summary
- Sustained Regional Radiation Management can have large impacts globally (ex. simulated RRM in north america creates waring in arctic and precipitation changes in the pacific)
- Spot interventions, to counteract a heat wave for example, have much less global effects, with local reduction of temperature
