Abstract Climate change forecasts predict impacts that will increasingly expose coastal residents to existential risks, necessitating aggressive adaptation. While the polarization of climate change attitudes in American politics represents a barrier to climate adaptation efforts, it is not well-understood how political ideology mediates how individuals connect the abstract concept of “climate change” to concrete experiences with environmental risks. Understanding this link in the context of adaptation decision-making is important, as the effects of many, household-level adaptation efforts compound over space and time, affecting community flood risk and vulnerability. This paper asks, how do political ideologies interact with threat perception to affect coastal climate adaptation decisions? We frame this analysis using the Theory of Planned Behavior (TPB) and Protection Motivation Theory (PMT). Using responses from a survey of residents (n = 164) in North Carolina’s (USA) Albemarle-Pamlico Peninsula, we examine how measures of residents’ subjective norms, threat-appraisals, and self-efficacy influence their intent to retreat or topographically adapt. We find that, despite political polarization around climate change, generally, when given concrete examples of risk, respondents’ political beliefs appear unrelated to their plans to protect their property and livelihoods.

从抽象的未来到具体的经验：政治意识形态如何与威胁感知相互作用以影响气候适应决策？

摘要 气候变化预测预测的影响将越来越多地使沿海居民面临生存风险，需要积极适应。虽然美国政治中气候变化态度的两极分化代表了气候适应努力的障碍，但政治意识形态如何调节个人如何将“气候变化”的抽象概念与环境风险的具体经验联系起来，这一点尚不清楚。在适应决策的背景下理解这种联系很重要，因为许多家庭层面的适应努力的影响会随着空间和时间的推移而复杂化，从而影响社区洪水风险和脆弱性。这篇论文问，政治意识形态如何与威胁感知相互作用以影响沿海气候适应决策？我们使用计划行为理论 (TPB) 和保护动机理论 (PMT) 来构建此分析。利用对北卡罗来纳州（美国）Albemarle-Pamlico 半岛居民 (n = 164) 的调查反馈，我们研究了居民主观规范、威胁评估和自我效能感的测量如何影响他们撤退或地形适应的意图。我们发现，尽管围绕气候变化存在政治两极分化，但一般而言，当给出具体的风险示例时，受访者的政治信仰似乎与他们保护财产和生计的计划无关。我们研究了居民的主观规范、威胁评估和自我效能感如何影响他们撤退或地形适应的意图。我们发现，尽管围绕气候变化存在政治两极分化，但一般而言，当给出具体的风险示例时，受访者的政治信仰似乎与他们保护财产和生计的计划无关。我们研究了居民的主观规范、威胁评估和自我效能感如何影响他们撤退或地形适应的意图。我们发现，尽管围绕气候变化存在政治两极分化，但一般而言，当给出具体的风险示例时，受访者的政治信仰似乎与他们保护财产和生计的计划无关。
