U.S. Climate Risk Projections by County, 2040-2049

The U.S. Climate Risk Projections by County, 2040-2049 data set contains a projection for 2040-2049 risk for the entire contiguous U.S. at the county level with a novel climate risk index integrating multiple hazards, exposures and vulnerabilities. Multiple hazards such as weather and climate are characterized as a frequency of heat wave, cold spells, drought, and heavy precipitation events along with anomalies of temperature and precipitation using high resolution (4 km) downscaled climate projections. Exposure is characterized by projections of population, infrastructure, and built surfaces prone to multiple hazards including sea level rise and storm surges. Vulnerability is characterized by projections of demographic groups most sensitive to climate hazards. This approach can guide planners in targeting counties at most risk and where adaptation strategies to reduce exposure or protect vulnerable populations might be best applied.

《美国县域气候风险预测（2040-2049）》数据集包含了针对整个美国连片地区的2040-2049年气候风险预测，该预测以县级行政区为单位，并采用了一种创新的气候风险指数，该指数综合了多种风险、暴露和脆弱性。多种风险，如天气和气候风险，被描述为热浪、寒潮、干旱和重降水事件的频率，以及温度和降水异常，这些均基于高分辨率（4公里）降尺度气候预测。暴露性由易受多种风险影响的，包括海平面上升和风暴潮在内的，人口、基础设施和建筑表面的预测构成。脆弱性则通过易受气候风险影响的特定人口群体的预测来表征。此方法有助于规划者识别风险最高的县，并在这些地区实施适应策略，以减少暴露或保护易受伤害的群体。
