'Astronomical Causes of Climate Change' - More factors than they tell you about in the press: solar effects, Milankovitch etc.
The areas discussed include:
| Solar Output - Long Term | Snowball Earth to Boiling Oceans |
| Cyclical Variations in Solar Output | Sunspot Cycles - 11 to 2500 years and more; Recent climatic ups and downs; Carbon-14 and beryllium-10; Mechanism |
| Geological Factors | Ocean Circulation; Distribution of the continents - most of the land is in the northern hemisphere; Tambora; Toba |
| Orbital Factors - Galactic | The Sun's journey round the galaxy; Effect of interaction with dust clouds |
| Milankovitch Cycles - Eccentricity | How eccentricity changes; Seasonal effects; changes in insolation; Effect of Jupiter; Tidal effects |
| Milankovitch Cycles - Precession | North Star changing; Mechanism - not steady (an annual cycle) |
| Milankovitch Cycles - Axial Tilt (Obliquity) | Causes (mechanism); Moon's current damping effect; Long term lunar resonance problems |
| Orbital Inclination | Earth versus the invariant plane; Interplanetary dust |
| Problems/Answers | The 'stage 5' problem - climate change precedes Milankovitch factors; Best guess about current situation |
| Conclusion | Anthropogenic effects |
