Follow this link for course description.

While this course includes ten lectures, you are free to join the group at any time. Each lecture stands on its own so if you miss a lecture or want to start part-way into the course, no problem.

10 Great What Ifs will be followed by a 36 lecture series, Earth at the Crossroads: Understanding the Ecology of a Changing Planet. But more on this later.
