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 … WebAug 22, 2024 · Eccentricity : When the Earth is closer to the Sun, the climate is warmer and this cycle also impacts the length of the seasons. The amount of a shape’s (Earth’s orbit) deviation from being a circle is called ‘eccentricity.’ Earth’s annual journey around the Sun is not completely in circular path, but it is very close to circular.
WebECCENTRICITY Milankovitch’s first cycle has to do with eccentricity. Eccentricity is a measure of how much the ellipse of the Earth’s orbit differs from a circle (Figure 4). The ellipse on the left is almost a circle. The ellipse on the right is more like an oval, therefore more eccentric than the ellipse on the left.
