US Congressional Research Services: Geoengineering: Governance and Technology Policy (update)
Bracmort, Kelsi; Lattanzio, Richard K. (2013): Geoengineering. Governance and Technology Policy. Congressional Research Service. Washington, D.C. (R41371).
Updated report of the US Congressional Research Service. "With the possibility that geoengineering technologies may be developed and that climate change will remain an issue of global concern, policymakers may determine whether geoengineering warrants attention at either the federal or international level. If so, policymakers will also need to consider whether geoengineering can be effectively addressed by amendments to existing laws and international agreements or, alternatively, whether new laws and international treaties would need to be developed."
