Impact analysis
Which land around a point is exposed to the climate change the models agree on: MapBiomas land use in a circle, read against three CMIP6 models for its 0.25° cell.
How to use it
- Open /app/ and search a CEP, address, city or coordinate — or pan the map. A searched place only frames the map.
- Choose the radius (1–20 km) and the emissions scenario (SSP2-4.5 or SSP5-8.5).
- Click a point. The circle and the dashed climate-model cell are drawn; land use and climate are read in parallel.
- Read Story (probable exposed area per hazard), Land use, Climate (each model's change and agreement) and Method. The address bar keeps the point, radius and scenario, so the result can be shared.

Data sources

- NASA NEX-GDDP-CMIP6 — EC-Earth3, MPI-ESM1-2-HR, CMCC-ESM2

- OpenStreetMap Nominatim, ViaCEP
Limits & caveats
- The climate signal is one value per 0.25° (~27 km) cell; the global models behind it run at ~100 km. Inside a cell only land use varies.
- Land use is held fixed at the latest MapBiomas (Brazil) or AAFC (Canada) year; Brazil and Canada only. AAFC's inventory is agricultural and stops near 55°N.
- Probable exposure = land use × a regional signal — not a modelled impact, a forecast for a field or an assessment of a property.
