Earth's eccentricity cycle
Webeccentricity, axial tilt, and precession of the Earth's orbit vary in several patterns, resulting in 100,000-year ice age cycles of the Quaternary glaciation over the last few million … WebThink about Eccentricity. In order for the ice sheets to grow enough to create an ice age, you need "summer" to happen when the earth is furthest away from the sun (cooler summers, little ice melt) and "winter" to …
