Tools
Explore Global Systems Lab’s interactive simulators. Each tool opens on its own page so you can bookmark, share, and return to specific scenarios.
Interactive simulators
Open any simulator below. Each page includes a short guide and a shareable URL.
Human Experience Engine
Explore how policy, economy, health, culture, and environment interact. Run scenarios and compare wellbeing outcomes.
Earth System Simulator
Model global temperature response to greenhouse gases, aerosols, and ocean heat uptake. Compare equilibrium and time-varying scenarios.
Cosmic Habitability Simulator
Estimate surface temperature and liquid-water bounds across stellar and planetary parameters. Explore insolation, greenhouse effects, and uncertainty.
Fractal Explorer
Render Mandelbrot, Julia, and Burning Ship fractals with presets, zoom controls, and color maps to learn complex dynamics visually.
Biome Simulator
A scientific, browser-based ecosystem simulator. Explore food-web dynamics with Holling functional responses, genetic drift, and speciation. Observe and alter Allee effects, and climate–fitness interactions across 12 distinct biomes. Then push ecosystems to their limits with natural disasters and mass-extinction pulses.
Earthquake Explorer
Visualise live earthquake data from the USGS on an interactive map. Filter by region, date range, and magnitude to explore seismic trends, depth patterns, and tectonic activity anywhere on Earth. Powered by the USGS Earthquake Hazards Program real-time feed.
NOAA Weather Map
Free real-time NOAA weather map. Live conditions, 7-day forecasts, wind, snowfall, and severe weather alerts for all 50 US states. No account or API key needed.
Global Simulator
See how the world's future changes based on choices about climate, energy, population and more.
