Presets

Three slow changes in Earth's orbit — the stretch of its ellipse (eccentricity), the tilt of its axis (obliquity), and the wobble of that axis (precession) — combine to modulate summer sunlight at high latitudes. That insolation rhythm paces the glacial-interglacial cycles recorded in ice and ocean cores.

▶ Run in Python

Data Inspector

Eccentricity~100 kyr
Obliquity~41 kyr
Precession~23 kyr

Insolation forcing

Reading this result: With obliquity weighted highest, a ~41 kyr beat dominates — the pattern that paced glacial cycles before ~1 million years ago, when axial tilt led the forcing.

Presets

A planet warms until it radiates away exactly the sunlight it absorbs. Balancing absorbed power S(1−α)/4 against εσT⁴ gives the equilibrium temperature. An emissivity below 1 represents greenhouse gases trapping outgoing infrared, raising the surface temperature.

▶ Run in Python

Absorbed power238 W/m²
No-greenhouse T-18.6 °C
Greenhouse warming+32.3 °C

Governing equation

Reading this result: Dropping emissivity below 1 mimics greenhouse gases: they add 32 °C on top of the -19 °C bare-rock temperature.
