Abstract Coastal communities are among the most vulnerable to climate risks. Despite the negligence of climate policy at the federal level in the United States, subnational governments have taken action to adapt to climate change impacts. Using national-level data on subnational government climate activities, this research examines three aspects of coastal community adaptation actions. First, it examines whether there are differences in climate adaptation activity between coastal and non-coastal communities. It then tests the relative importance of political partisanship, population, perception of climate risk, and awareness of state-level climate planning effort. Lastly, it examines the impact of participation within climate policy networks on the likelihood of a subnational government taking a climate adaptation action. Three types of network partners are examined: those focused on sea-level rise and coastal communities, climate change mitigation, and general environmental organizations. Concern about severe storms, awareness of state plans, and having a network partner focused either on climate mitigation or the environment were found to be statistically significant indicators of climate adaptation action. The paper discusses the importance of understanding the localized context of adaptation within nested governance structures, and how informal policy networks can facilitate learning and innovation across coastal communities.

沿海社区对气候风险的适应响应模式

摘要 沿海社区是最容易受到气候风险影响的社区之一。尽管美国联邦层面的气候政策存在疏忽，但地方政府已经采取行动来适应气候变化的影响。本研究使用有关次国家政府气候活动的国家级数据，考察了沿海社区适应行动的三个方面。首先，它检查了沿海和非沿海社区之间的气候适应活动是否存在差异。然后，它测试了政治党派、人口、对气候风险的看法以及对州级气候规划工作的认识的相对重要性。最后，它研究了参与气候政策网络对地方政府采取气候适应行动的可能性的影响。研究了三种类型的网络合作伙伴：那些专注于海平面上升和沿海社区、减缓气候变化和一般环境组织的合作伙伴。对严重风暴的担忧、对州计划的认识以及让网络合作伙伴专注于减缓气候变化或环境是气候适应行动的统计显着指标。本文讨论了理解嵌套治理结构中适应的本地化背景的重要性，以及非正式政策网络如何促进沿海社区的学习和创新。并且发现网络合作伙伴专注于减缓气候变化或环境是气候适应行动的统计显着指标。本文讨论了理解嵌套治理结构中适应的本地化背景的重要性，以及非正式政策网络如何促进沿海社区的学习和创新。并且发现网络合作伙伴专注于减缓气候变化或环境是气候适应行动的统计显着指标。本文讨论了理解嵌套治理结构中适应的本地化背景的重要性，以及非正式政策网络如何促进沿海社区的学习和创新。
