What will the Milankovitch Cycles Do To Earth?

The Milankovitch cycles describe the effects of small changes in the Earth's movement on its climate over thousands of years. The cycles affect how much solar energy hits the Earth.
The term is named after the Serbian geophysicist and astronomer Milutin Milanković.
There are three different positional cycles:
- Eccentricity: Earth's orbit around the sun in an ellipse shape (cycle of about 100,000 years).
- Axial tilt: Earth's axial tilt is from 21.5 to 24.5 degrees (cycle of about 41,000 years).
The tilt is the reason that we experience seasons.
- Precession: Earth also wobbles like a top as it spins on the axis (cycle of about 26,000 years).
Factors influence the Milankovitch cycles:
- Axial tilt or obliquity (ε).
- Eccentricity (e).
- Longitude of perihelion ( sin(ϖ).
- Precession index (e sin(ϖ) )
