The three basic cyclic reasons why the temperature of the Earth has fluctuated over time are Eccentricity, Obliquity and Precession.

The Milankovitch Cycles

The Milankovitch Cycles are defined as the cyclical movement related to the Earth's orbit around the sun. These cycles cause variations in the amount of solar energy reaching the Earth.

Milankovitch Cycle was developed by the Serbian mathematician called Mulutin Milankovitch.

The climatic effects of the Milankovitch Cycles include:

  • Eccentricity: This is defined as the shape of Earth's orbit. This cycle is the reason why the seasons are slightly different in length.

  • Obliquity: This is defined as the angle that Earth's axis is tilted with respect to Earth's orbital plane. The greater Earth’s axial tilt angle, the more extreme our seasons are.

  • Precession: This is defined as the direction that Earth's spin axis is pointed. Axial precession makes seasonal contrasts more extreme in one hemisphere and less extreme in the other.
