海平面上升通过提高基线高度放大了极端海平面的频率。放大通常被预测为任意的未来年份和基准频率。因此,考虑到当地目前的海岸保护程度,这些预测并不表明何时可能超过洪水风险阈值。为了更好地支持适应规划和比较脆弱性分析,我们使用IPCC AR6到2150年的海平面上升预测,预测了极端海平面相对于估计的当地防洪标准的频率放大的时间。我们的中央估计表明,在未来30年(大型适应措施可能采取的提前时间)内,超过这些保护程度的频率将是所考虑的验潮仪的26%和32%,对于低排放和高排放情景,每年分别为4%和8%。适应规划者可以使用我们的框架来评估保护性基础设施的可用准备时间和使用寿命。
Sea-level rise amplifies the frequency of extreme sea levels by raising their baseline height. Amplifications are often projected for arbitrary future years and benchmark frequencies. Consequently, such projections do not indicate when flood risk thresholds may be crossed given the current degree of local coastal protection. To better support adaptation planning and comparative vulnerability analyses, we project the timing of the frequency amplification of extreme sea levels relative to estimated local flood protection standards, using sea-level rise projections of IPCC AR6 until 2150. Our central estimates indicate that those degrees of protection will be exceeded ten times as frequently within the next 30 years (the lead time that large adaptation measures may take) at 26% and 32% of the tide gauges considered, and annually at 4% and 8%, for a low- and high-emissions scenario, respectively. Adaptation planners may use our framework to assess the available lead time and useful lifetime of protective infrastructure.
