Coursera.org free Science of Climate Change class

 There's a interesting online class about climate change starting at https://www.coursera.org/course/globalwarming? - 

It's free, so if you're curious and want to learn more about how our global climate system operates here's a great opportunity.

Global Warming: The Science of Climate Change

This class describes the science of global warming and the forecast for humans’ impact on Earth’s climate. Intended for an audience without much scientific background but a healthy sense of curiosity, the class brings together insights and perspectives from physics, chemistry, biology, earth and atmospheric sciences, and even some economics—all based on a foundation of simple mathematics (algebra).

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.

Course Syllabus

Week 1: Our First Climate Model
Week 2: On Greenhouse Gases and the Atmosphere
Week 3: More on the Atmosphere – and Feedbacks
Week 4: The Carbon Cycle
Week 5: The Perturbed Carbon Cycle
Week 6: The Smoking Gun and Paleoclimate
Week 7: Impacts
Week 8: Mitigation

Recommended Background

This course assumes no scientific knowledge and is geared toward a general audience. The problem sets require high-school-level algebra. The optional data assignments require a fair amount of number crunching, but this can be accomplished with a spreadsheet application such as Google Spreadsheets.
