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.
3.4 Earth’s Orbital Fluctuations and Climate Change
WebJul 25, 2024 · Orbital eccentricity is currently dropping, moving towards circular, so we're not in a period of expected significant changes. (The increased CO2 would prevent an ice age now anyway, but that's another story). Earth's orbital cycles are in more of a holding pattern than moving towards an ice age.

Currently, northern summer occurs near aphelion. Milutin Milankovitch first theorized that precession and two of the Earth's other orbital parameters—eccentricity and obliquity—affected climate. Image and Animation by Robert Simmon, NASA GSFC Web1 day ago · The eccentricity is excited to extremely high values with on the order of 10 −5 and the inclination can oscillate quite far away from 90°. ...
