🌍 Budyko-Sellers Energy Balance: Ice Line, Hysteresis and Snowball Earth Globe

A latitude-by-latitude energy balance climate model on a 3D globe: absorbed sunlight, outgoing infrared, poleward heat diffusion and the ice-albedo feedback. Change the Sun and CO2, watch the ice line move, and sweep the Sun to reveal the warm and snowball Earth hysteresis loop.
