🌍 Climate Century: Two-Box Energy Balance and Emission Pathways Lab

A 100-year toy climate model: CO2 forcing 5.35 ln(C/C0), a two-box (surface plus deep ocean) energy balance with adjustable climate sensitivity and ocean heat uptake, an impulse-response carbon cycle, emission-pathway presets and semi-empirical sea-level rise, shown on a Blender-built globe and coastline. Checked numerically against the analytic equilibrium sensitivity and the closed-form step response; a teaching toy, not a forecast.
