Earth and Life

An introduction to Gaia by James Lovelock.

Daisyworld: James Lovelock and Gaia

James lovelock discusses the original Gaia theory and how it developed and led to the Daisy world model.

Daisyworld: Gaia and Daisyworld

James Lovelock continues to look at the idea of Daisy world and its links to nature and systems.

Daisyworld: Self regulation

James Lovelock talks about Gaia theory and predictions that tested the theory.

Daisyworld: Gaia theory and the real world

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.

Tibet: the Raymo-Ruddiman Hypothesis

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.

Tibet: Berner's model of the carbon cycle

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.

Tibet: the geological history

The importance of strontium isotopes in chemical weathering, a comparison of two models to assess the validity of the Raymo-Ruddiman hypothesis.

Tibet: The signifiicance of the strontium ratio

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.

Tibet: evidence for and against the Raymo- Ruddiman Hypothesis

Did the scientists visiting Tibet reach any different conclusions about the Raymo Ruddiman hypothesis.

Tibet: Field trip conclusions

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.

Volcanoes: eruptions and climatic effects

A look at how volcanic eruptions effect the climate.

Volcanoes: How eruptions affect climate

A look at climatic effects that have occurred from the eruption of volcanoes through history.

Volcanoes: Historic eruptions and their climatic effects

Investigating the impacts of magma eruptions on the environment.

Volcanoes: Effects of magma eruptions

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.
