Lecture 12: Climate Regulation and Climate Change
What are the main mechanisms of climate regulation and climate
change that have operated through Earth's history? The Earth's
climate is regulated by a Carbon Dioxide thermostat that is the
interaction between the Greenhouse Effect and the CO2 Cycle. I describe
the CO2 cycle and its role in regulating global temperature. I will
then discuss other influences on climate, and periods of glaciation (ice
ages) in the recent and distant past, including the possible Snowball
Earth events in the early and late Proterozoic Eon. Recorded live on
2009 Oct 8 in Room 1005 Smith Laboratory on the Columbus campus of The
Ohio State University.
