sci.climate-sensitivity-ECS Calculator
Calculates Equilibrium Climate Sensitivity (ECS) — global mean temperature change per CO₂ doubling — from climate model outputs or paleoclimate constraints. IPCC AR6 assessed ECS: likely range 2.5–4.0 °C, best estimate 3 °C — ECS uncertainty is the dominant source of uncertainty in long-term climate projections.
