Zero Backend
Your browser calls the sources directly — NOAA’s Global Monitoring Laboratory (via global-warming.org), Our World in Data’s grapher API, and the World Bank API. All are free, key-less, and CORS-open. Nothing passes through this site’s server.
Graceful Fallback
If a source is unreachable, its card shows the model’s static baseline instead and says so. The simulation never depends on the network — live values are an overlay, not a requirement. Results are cached in your browser for six hours.
Apples & Oranges
The model’s scores are composite 0–100 indices; live values are raw physical measurements. Where a direct comparison exists (CO₂ ppm, warming, renewable share, emissions, poverty) the card shows the drift between the model’s 2026 assumption and reality.
