Decision-making barriers challenge port administrators to adapt and build resilience to natural hazards. Heavy rains, storms, sea level rise (SLR), and extreme heat can damage the critical coastal infrastructure upon which coastal communities depend. There is limited understanding of what impedes port decision makers from investing resources in climate and extreme weather adaptations. Through semi-structured interviews of 30 port directors/managers, environmental specialists, and safety planners at 15 medium- and high-use ports of the U.S. North Atlantic, this paper contributes a typology of seven key adaptation barriers. We measured shared knowledge of the identified barriers using a cultural consensus model (CCM). Knowledge of the barriers that prevent or delay resilience investments can help the decision makers direct their resources to help reduce coastal vulnerability and support safe and sustainable operations of U.S. ports. Such actions also serve to help prepare the marine transportation system for future climate and extreme weather events.

决策者在气候和极端天气适应方面的障碍：北大西洋高中用途港口的研究

决策壁垒挑战港口管理者以适应和增强抵御自然灾害的能力。大雨，暴风雨，海平面上升（SLR）和极端高温会破坏沿海社区赖以生存的关键沿海基础设施。对于阻碍港口决策者在气候和极端天气适应方面投入资源的认识有限。通过对美国北大西洋的15个中度和高使用率港口的30位港口总监/经理，环境专家和安全计划人员进行的半结构式访谈，本文贡献了七个主要适应障碍的类型。我们使用文化共识模型（CCM）测量了已识别障碍的共享知识。了解阻止或延迟弹性投资的障碍，有助于决策者引导其资源，以帮助减少沿海脆弱性并支持美国港口的安全和可持续运营。这些行动也有助于为未来的气候和极端天气事件做好海上运输系统的准备。
