How does orbital eccentricity affect climate

WebFeb 3, 2024 · When the orbit is very elliptical (oval shaped), one hemisphere will have hot summers and cold winters and the other hemisphere will have warm summers and cool winters. When the orbit is more circular, both hemispheres will have similar seasons. Precession, in the third cycle, has a periodicity of about 22,000 years. WebMay 10, 2024 · The Earth’s eccentricity can significantly affect the weather here on the surface. For example, when the Earth’s orbit is at its most elliptical, the planet experiences reduced sunlight over many thousands of years, resulting in a significantly cooler Earth.
