Learn how the Earth's not-so-circular orbit around the sun affects our climate by exploring this site. - Global Climate Change: Effect of the Earth's Orbit
The solar energy received by the earth is both cyclical and variable due to the changes in the earth's orbit and inclination. Explore this site to find out more about these variations and their effect on global climates.
- Ask a High Energy Astronomer, NASA
How does the earth's tilt affect the changing of the seasons and what different angles cause those different seasons? - Milankovitch Cycles and Glaciation
Learn about the connection between eccentricity, axial tilt, and precession in relation to past glaciations by visiting this site.
- Precession, NASA
This article describes the development and background behind the idea of precession. - Precession, University of Oregon
