ABSTRACT

Solar geoengineering (SG) may be a helpful tool to reduce harms from climate change, yet further research into its potential benefits and risks must occur prior to any implementation. So far, however, organized research on SG has been absent from the U.S. national policy agenda. We apply the Multiple Streams Approach analytical framework to explain why a U.S. federal SG research program has failed to materialize up to now, and to consider how one might emerge in the future. We argue that establishing a federal program will require the formation of an advocacy coalition within the political arena that is prepared to support such a policy objective. A coalition favoring federal research on SG does not presently exist, yet the potential nucleus of a future political grouping is evident in the handful of ‘pragmatist’ environmental organizations that have expressed conditional support for expanded research.

摘要

太阳能地球工程 (SG) 可能是减少气候变化危害的有用工具，但在任何实施之前必须对其潜在收益和风险进行进一步研究。然而，到目前为止，美国国家政策议程中还没有对 SG 进行有组织的研究。我们应用多流方法分析框架来解释为什么美国联邦 SG 研究计划至今未能实现，并考虑未来可能会如何出现。我们认为，建立联邦计划需要在政治领域内形成一个支持这一政策目标的倡导联盟。目前不存在支持联邦研究 SG 的联盟，
