Earth and Life - for iPod/iPhone
by 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.
Episodes
-
Earth and Life
A short introduction to this album.
-
Daisyworld: James Lovelock and Gaia
An introduction to Gaia by James Lovelock.
-
Daisyworld: Gaia and Daisyworld
James lovelock discusses the original Gaia theory and how it developed and led to the Daisy world model.
-
Daisyworld: Self regulation
James Lovelock continues to look at the idea of Daisy world and its links to nature and systems.
-
Daisyworld: Gaia theory and the real world
James Lovelock talks about Gaia theory and predictions that tested the theory.
-
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.
-
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.
-
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.
-
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.
-
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.
-
Tibet: Field trip conclusions
Did the scientists visiting Tibet reach any different conclusions about the Raymo Ruddiman hypothesis.
-
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.
-
Volcanoes: How eruptions affect climate
A look at how volcanic eruptions effect the climate.
-
Volcanoes: Historic eruptions and their climatic effects
A look at climatic effects that have occurred from the eruption of volcanoes through history.
-
Volcanoes: Effects of magma eruptions
Investigating the impacts of magma eruptions on the environment.
-
Volcanoes: Flood Basalt and itys effects
The importance of flood basalt provinces in earth science.
-
Volcanoes: eruptions and mass extinctions
A look at mass extinctions and whether they could be caused by flood basalts events.
