Episode notes
Models Capture Big Patterns Not Every Detail
- Climate models simplify immense complexity by using physics and observations to simulate long-term trends rather than every detail.
- Even coarse models have revealed robust truths about Earth's past and future climate behavior.
Richardson's Hand-Calculated Forecast
- Louis Fry Richardson manually computed weather predictions during World War I and spent weeks on a single forecast.
- His work showed the conceptual possibility of numerical weather prediction before computers existed.
Early Models Predicted CO2 Warming
- Manabe and colleagues advanced climate modeling by building grid-based simulations and parameterizations for unresolved processes.
- Early models predicted CO2-driven warming close to modern estimates, showing early model skill.
