Why is sea level rise important?

Sea level rise increases the frequency and severity of storm surges and coastal flooding, causing serious damage to critical infrastructure and leading to the displacement of coastal communities around the world. Globally, more than 600 million people live in low‐lying coastal areas at less than 10m elevation, and the population of these regions is expected to exceed 1 billion by 2050 (Neumann et al., 2015). In the United Kingdom, current annual damages from coastal flooding are estimated at over £500 million per year (Edwards, 2017), and costs of damage are likely to increase under projections of future sea level rise.

气候变化如何影响海平面

为什么海平面上升很重要？

海平面上升增加了风暴潮和沿海洪水的频率和严重性，严重破坏了关键基础设施，并导致世界各地沿海社区流离失所。全球范围内，有超过6亿人生活在海拔低于1000万的低海拔沿海地区，到2050年，这些地区的人口预计将超过10亿（Neumann等，2015）。在英国，目前沿海洪水造成的年度损失估计每年超过5亿英镑（Edwards，2017年），在未来海平面上升的预测下，损失成本可能会增加。
