- Astronomical Forcing
- Change in the amount of energy distributed by the Sun.
- Change in the distribution of energy from the sun.
- Changes over 100,000 years.
- Stage One - Stretch
- 96,000 years
- Orbit changes from perfect to elipse and back to perfect again.
- This changes distance from the Sun to the Earth.
- Alters the amount of energy the earth receives.
- When perfect there is equal distribution.When there is elipse some areas of the globe receive more energy than others.
- Alters the amount of energy the earth receives.
- This changes distance from the Sun to the Earth.
- Stage Two -Tilt
- 41,000 years
- Earth alter tilt from 21.8 to 24.4 degrees
- Alters the amount of energy the earth receives. In some areas
- Tropics become larger.
- Area beyond tropics become smaller.
- Alters the amount of energy the earth receives. In some areas
- Stage Three - Wobble
- Earth Wobbles
- Seasons will swap over.
- Sun is closest to Earth in January. Summer in Northern Hemisphere
- Sun is furthest away from Earth in June. Winter in the Northern Hemisphere.
- During Wobble the summer and winter will become mild and then eventually swap over. Sun will still be closest in January and furthest in July.
- Sun is closest to Earth in January. Summer in Northern Hemisphere
- During Wobble the summer and winter will become mild and then eventually swap over. Sun will still be closest in January and furthest in July.
- Seasons will swap over.
- 22,000 years
- Earth Wobbles
