Abstract Climate change is imposing substantial consequences across physical and social infrastructures. The extent of social disruption and risk to human health are, however, potentially much broader than these general consequences, taken individually, would suggest. To address this gap, we assess the distribution of contaminated sites in the United States (US) and then estimate the impact that flood hazards in urban areas will have on these contaminated sites. Using these measures, we draw inferences about the risk of contamination from climate-impacted extreme weather events, climate adaptation at the local level, social risk and how it is distributed, and a broader understanding of the potential global consequences of climate change. In this paper we address three critical points: 1) the role classification of contaminated sites on our understanding of risk due to climate change; 2) the relationship between contaminated sites and flood risk; and 3) the potential for climate adaption strategies to mediate this risk. We estimate that of the roughly one-third of the US population living in urban areas, up to 3,338,518 people, are living in high-risk flood zones near contaminated sites. Our results suggest severe potential implications for estimates of the negative consequences from climate change and contamination and provide critical insights into the relationship between climate change and the built environment for urban planners and environmental policy makers and managers alike.

毒性在不断变化的气候中传播

摘要 气候变化正在对物理和社会基础设施造成重大影响。然而，社会混乱和人类健康风险的程度可能比单独考虑的这些一般后果要广泛得多。为了弥补这一差距，我们评估了美国 (US) 受污染场地的分布，然后估计了城市地区的洪水灾害对这些受污染场地的影响。使用这些措施，我们推断出受气候影响的极端天气事件造成的污染风险、地方层面的气候适应、社会风险及其分布方式，以及对气候变化潜在全球后果的更广泛理解。在本文中，我们解决了三个关键点：1) 污染场地的分类对我们理解气候变化风险的作用；2）污染场地与洪水风险的关系；3) 气候适应战略在调节这种风险方面的潜力。我们估计，在大约三分之一居住在城市地区的美国人口中，多达 3,338,518 人生活在受污染地点附近的高风险洪水区。我们的结果表明对气候变化和污染的负面影响的估计具有严重的潜在影响，并为城市规划者、环境政策制定者和管理人员等提供关于气候变化与建筑环境之间关系的重要见解。3) 气候适应战略在调节这种风险方面的潜力。我们估计，在大约三分之一居住在城市地区的美国人口中，多达 3,338,518 人生活在受污染地点附近的高风险洪水区。我们的研究结果表明对气候变化和污染的负面影响的估计具有严重的潜在影响，并为城市规划者、环境政策制定者和管理者等提供关于气候变化与建筑环境之间关系的重要见解。3) 气候适应战略在调节这种风险方面的潜力。我们估计，在大约三分之一居住在城市地区的美国人口中，多达 3,338,518 人生活在受污染地点附近的高风险洪水区。我们的研究结果表明对气候变化和污染的负面影响的估计具有严重的潜在影响，并为城市规划者、环境政策制定者和管理者等提供关于气候变化与建筑环境之间关系的重要见解。
