Coursera.org online Climate education classes

Any of you folks familiar with Coursera.org online classes?
I took one of these last year and they’ve got another 8 week course starting right now, that I think I’ll do.
Maybe some around here would be interested.
It’s lectures, a touch of home work, quizzes and all

Each week consists of several short video lectures and a set of activities to help you master the material. There are two paths through the course — you can focus on the math or quantitative assignments; or you can focus on explanatory or qualitative assignments. You are also welcome to work on all the assignments. Whichever path you choose, statements of accomplishment (or of distinction) will be available to students who complete the course at a satisfactory level. Everything you need to know is on the Course Details page.
