Climate Change: A Coordinated Strategy Could Focus Federal Geoengineering Research and Inform Governance Efforts

Policymakers have raised questions about geoengineering--large-scale deliberate interventions in the earth's climate system to diminish climate change or its impacts--and its role in a broader strategy of mitigating and adapting to climate change. Most geoengineering proposals fall into two categories: carbon dioxide removal (CDR), which would remove carbon dioxide (CO2) from the atmosphere, and solar radiation management (SRM), which would offset temperature increases by reflecting sunligh...
