Earth and Life - for iPad/Mac/PC: Recent Episodes
The Open University
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.
James lovelock discusses the original Gaia theory and how it developed and led to the Daisy world model.
Transcript -- James lovelock discusses the original Gaia theory and how it developed and led to the Daisy world model.
James Lovelock continues to look at the idea of Daisy world and its links to nature and systems.

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

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.

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.

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