How this works
ClimaLab turns published climate science into something you can explore for the place you actually live. Every figure comes from an observational record or a published climate model.
Projection, not forecast
A forecast describes a specific day. A projection describes the typical climate of a future decade under a particular emissions pathway. ClimaLab does not claim to predict the weather on a date decades from now.
Where the numbers come from
The observed baseline uses ERA5 reanalysis for 2005–2024. Projections use downscaled CMIP6 HighResMIP models, compare each model with observations at the same location, and apply bias correction before combining the results.
What each hazard measures
- Extreme Heat
- Days per year at or above 95°F (35°C).
- Heavy Rain & Flood
- Days per year with at least 1 inch (25 mm) of precipitation.
- Drought & Water Stress
- The longest annual run of days with less than 1 mm of rain.
- Wildfire & Smoke
- Hot days combined with a dry period, used as a simplified fire-weather proxy.
- Coastal Flood & Hurricane
- An exposure index based on elevation, distance to coast and cyclone climatology.
What this cannot tell you
Risk scores are city-scale estimates from climate-model grids. They cannot describe an individual property, street, or floodplain boundary, and they are not emergency, insurance, medical, property, or legal advice.
Live event feed
Active events on the globe come from NASA EONET. Severity is inferred only to order the display; it is not an official hazard rating.
Imagery and attribution
The globe uses NASA Blue Marble imagery. NASA does not endorse ClimaLab. Climate and geocoding data are served via Open-Meteo; ERA5 is produced by ECMWF and Copernicus, and CMIP6 output comes from participating modelling groups.
