"Three characteristics of Earth's
orbital motion change slightly over
long periods of time. These cyclical
changes cause differences in the
amount of sunlight the Northern and
Southern Hemispheres receive.
Analysis of deep-sea sediments has
shown that these changes are closely
associated with climate change." |

Three Astronomical Factors: |
|
Procession:
The orientation of our axis in it's rotation |
|
Eccentricity:
The shape of our solar orbit |
|
Obliquity: The angle between our axis and the line of
perpendicular to the orbital plane |

Milankovitch Theory
describes the collective
effects of changes in the
Earth's
movements upon its climate,
named after
Serbian
civil
engineer
and
mathematician
Milutin
Milanković,
who worked on it during
First
World War
internment. Milanković
mathematically theorised
that variations in
eccentricity,
axial
tilt,
and
precession
of the Earth's orbit
determined climatic patterns
on Earth.
