Research on global sun block needed now

David W. Keith, Edward Parson & M. Granger Morgan

Geoengineering studies of solar-radiation management should begin urgently, argue David W. Keith, Edward Parson and M. Granger Morgan — before a rogue state decides to act alone.


  • Field testing is required to understand the risks of solar-radiation management (SRM)
  • Linked activities must create norms and understanding for international governance of SRM
  • If SRM is unworkable, the sooner we know, the less moral hazard it poses
