Lecture 12: Climate Regulation and Climate Change
What are the main mechanisms of climate regulation and climate\nchange that have operated through Earth's history? The Earth's\nclimate is regulated by a Carbon Dioxide thermostat that is the\ninteraction between the Greenhouse Effect and the CO2 Cycle. I describe\nthe CO2 cycle and its role in regulating global temperature. I will\nthen discuss other influences on climate, and periods of glaciation (ice\nages) in the recent and distant past, including the possible Snowball\nEarth events in the early and late Proterozoic Eon.
