About The Course
We start with basic principles governing Earth’s temperature. The class begins with the nature of heat and light, then builds the very simplest conceptual—and algebraic—model for the climate of a planet, including the greenhouse effect.
Over the following weeks, we introduce complexities of the real world to this model: how greenhouse gases are selective about what light they absorb, how the temperature structure and weather in the atmosphere set the stage for the greenhouse effect, and how feedbacks amplify it. From this point on the exercises will be based on on-line interactive models for various aspects of Earth’s climate and carbon cycle, exploring the topics described in the video lectures.
We then turn to the carbon cycle of the Earth, how it stabilizes Earth’s climate on some time scales but destabilizes it on others. The fate of fossil fuel carbon will be determined by its integration into Earth’s ongoing natural carbon cycle.
The class concludes with a look at the human impact on Earth’s climate: why we believe it’s changing, why we believe we’re changing it, the impacts that could have, and the options we have to mitigate the situation.
