Glacial erosion
Alpine Glaciers vs. Continental Ice Sheets
Glacial landforms:
Cirques, arretes, and horns
Glacial sediment:
till and loess
Moraines
The Pleistocene: Glacials vs. Interglacials
Glacials are about 5 degrees colder
Pollen, plankton and oxygen isotopes
- Oxygen isotopes: 15 glacials over 1.6 million years
What are the Causes of Glaciation?
120,000 year cyclicity
Not volcanoes
The Greenhouse effect
How it works
The carbon cycle
Coming Superinterglacial?
Milankovitch cycles
Cyclic changes in solar input
Modeling and the Importance of Feedback Mechanisms
Snow reflection
