SSP5-8.5 2085 stress test
Under the SSP5-8.5 stress test for 2085, the combined score is 43 of 100.
This cell's combined hazard score is 46.2; its strongest pillar is climate velocity at 84.6 and its weakest is earthquake at 6.0. Flood. Flood pillar 42.1, safer than 26% of land cells and level with 32%; modelled hundred-year river flood depth 0.053 m. Source: WRI Aqueduct Floods (vintage: WRI Aqueduct Floods v2 (historical baseline, 100-year RP)); ERA5 (vintage: ERA5 reanalysis 1991-2020). Tornado. Wind pillar 58.8, safer than 33% of land cells and level with 52%; tornado touchdowns nearby 1.9 touchdowns/decade. Source: NOAA Storm Prediction Center (vintage: 1950-2024). Hurricane. Wind pillar 58.8, safer than 33% of land cells and level with 52%; tropical storm passes nearby 0 storms/decade. Source: IBTrACS (vintage: v04r01). Earthquake. Earthquake pillar 6.0, safer than 6% of land cells and level with 1%; large earthquakes nearby since the start of the century before last 1.6 events/century. Source: USGS ComCat (vintage: ComCat M≥6.5 1900–2025, M≥5 1973–2025); USGS Slab2 (vintage: Slab2, March 2018). Climate velocity. Climate velocity pillar 84.6, safer than 85% of land cells; observed warming rate 0.20 °C/decade. Source: NASA GISTEMP (vintage: 2024). Coverage: No coast data exists for this cell, so it is left out of the combined score and the remaining pillar weights are renormalized. This is a statistical summary of public hazard data, a research estimate, not advice about any property or decision.
Terra scores ~10 km hexagonal cells from public global datasets — it is area analysis, not a property assessment. Tornado history covers the United States only; flood hazard is modeled at ~1 km and ignores local defenses; hurricane records before 1966 and wildfire records before 2001 are incomplete. Where data is missing or coarse for your area, Terra says so instead of guessing.
