This series of tracks focuses on geological phenomena, Gaia theory and volcanoes. Included is a discussion on Climate Change and whether the uplift of Tibet caused global cooling. Material is taken from The Open University Course S269 Earth and Life.
Track 5: Daisyworld: Gaia theory and the real world
James Lovelock talks about Gaia theory and predictions that tested the theory.

| 2 | Daisyworld: James Lovelock and Gaia | An introduction to Gaia by James Lovelock. Play now Daisyworld: James Lovelock and Gaia |
| 3 | Daisyworld: Gaia and Daisyworld | James lovelock discusses the original Gaia theory and how it developed and led to the Daisy world model. Play now Daisyworld: Gaia and Daisyworld |
| 4 | Daisyworld: Self regulation | James Lovelock continues to look at the idea of Daisy world and its links to nature and systems. Play now Daisyworld: Self regulation |

| 6 | Tibet: the Raymo-Ruddiman Hypothesis | John Kutzbach from the University of Wisconsin and Bill Ruddiman from the University of Virginia discuss modelling the effects that a high plateau has on climate using Tibet as an example. Play now Tibet: the Raymo-Ruddiman Hypothesis |
| 7 | Tibet: Berner's model of the carbon cycle | A look at Berner's model of the Carbon cycle and how it provided a basis for further research and experimentation into climate change by Maureen Raymo of MIT. Play now Tibet: Berner's model of the carbon cycle |
| 8 | Tibet: the geological history | A look at the geological history of Tibet and the Raymo Ruddiman hypothesis; that chemical weathering increased as the temperature dropped due to the rise in the plateau. Raymo and Ruddiman believed that the uplift of the Himalayas caused global cooling. Play now Tibet: the geological history |
| 9 | Tibet: The signifiicance of the strontium ratio | The importance of strontium isotopes in chemical weathering, a comparison of two models to assess the validity of the Raymo-Ruddiman hypothesis. Play now Tibet: The signifiicance of the strontium ratio |
| 10 | Tibet: evidence for and against the Raymo- Ruddiman Hypothesis | Is there really a link between the uplift of Tibet and climate change? Investigating when the change from building a plateau to destroying a plateau took place. Play now Tibet: evidence for and against the Raymo- Ruddiman Hypothesis |
| 11 | Tibet: Field trip conclusions | Did the scientists visiting Tibet reach any different conclusions about the Raymo Ruddiman hypothesis. Play now Tibet: Field trip conclusions |
| 12 | Volcanoes: eruptions and climatic effects | The effect that the eruption of Mount Pinatubo had on the atmosphere and climate and how the type of eruption can also impact on the climate. Play now Volcanoes: eruptions and climatic effects |
| 13 | Volcanoes: How eruptions affect climate | A look at how volcanic eruptions effect the climate. Play now Volcanoes: How eruptions affect climate |
| 14 | Volcanoes: Historic eruptions and their climatic effects | A look at climatic effects that have occurred from the eruption of volcanoes through history. Play now Volcanoes: Historic eruptions and their climatic effects |
| 15 | Volcanoes: Effects of magma eruptions | Investigating the impacts of magma eruptions on the environment. Play now Volcanoes: Effects of magma eruptions |
| 16 | Volcanoes: Flood Basalt and itys effects | The importance of flood basalt provinces in earth science. Play now Volcanoes: Flood Basalt and itys effects |
| 17 | Volcanoes: eruptions and mass extinctions | A look at mass extinctions and whether they could be caused by flood basalts events. Play now Volcanoes: eruptions and mass extinctions |
