目前估计美国财产面临沿海灾害和海平面上升（SLR）的风险，估计超过一万亿美元。尽管总体上是巨大的，但由于SLR的潜在损失取决于缓解，适应和暴露，并且在沿海城市之间的分布非常不均匀。我们提供了第一个分析如何暴露的变化（如何和何时）已经展开了超过一个世纪的沿海城市发展在美国。我们这样做，利用新的历史解决层的历史解决数据汇编为美国（HISDAC-美国）检查内和之间的SLR区的毗连美国自世纪初的建筑模式。我们的分析表明，SLR区发展更快，并继续有较高的结构密度比非沿海，城市和内陆地区。这些模式在受飓风影响的地区尤为突出。然而，历史上欠发达的沿海地区的密度水平现在正迅速向早期定居的SLR地区靠拢，其中许多地区已经达到建筑饱和。这些“饱和效应”表明，相对于保护以前未开发的土地而言，针对现有建筑物和已开发地区的适应政策可能越来越重要。
Current estimates of U.S. property at risk of coastal hazards and sea level rise (SLR) are staggering—evaluated at over a trillion U.S. dollars. Despite being enormous in the aggregate, potential losses due to SLR depend on mitigation, adaptation, and exposure and are highly uneven in their distribution across coastal cities. We provide the first analysis of how changes in exposure (how and when) have unfolded over more than a century of coastal urban development in the United States. We do so by leveraging new historical settlement layers from the Historical Settlement Data Compilation for the U.S. (HISDAC-US) to examine building patterns within and between the SLR zones of the conterminous United States since the early twentieth century. Our analysis reveals that SLR zones developed faster and continue to have higher structure density than non-coastal, urban, and inland areas. These patterns are particularly prominent in locations affected by hurricanes. However, density levels in historically less-developed coastal areas are now quickly converging on early settled SLR zones, many of which have reached building saturation. These “saturation effects” suggest that adaptation polices targeting existing buildings and developed areas are likely to grow in importance relative to the protection of previously undeveloped land.
