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.

Substantial Climate Response outside the Target Area in an Idealized Experiment of Regional Radiation Management

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
