I don't think my university (recently ranked 596 out of 600 colleges by Forbes, but not for this reason) offers a course that explains climate change and its social consequences.
There are a lot of barriers to offering such a course. Would it be a science course? In which scientific discipline? Just understanding the physical causes of climate change requires knowing more than just a little something about physics, chemistry, and earth science. So what department would own it? (We don't have an earth science or geography department.) Understanding the effects of climate change broadens the scope even further, to include (all) the life sciences, but especially ecology and the medical sciences. And also social science. Understanding the social causes and implications would require a yet broader course: communication, political science, economics, public policy, history, philosophy. At least those, and probably more.
Can such a course be taught only at the senior level, since it requires so much knowledge? If so, would there be any students who could fit it in their schedules among their other advanced courses? Or could it be a way to teach basic concepts from many disciplines in a way that provides the sort of meaningful context that gives sense to difficult ideas?
Even if such a course would have a market among lower-level students, how could they get credit for the course (except as an elective), given that my university is set up on a disciplinary model? And how could a team of teachers from different colleges (e.g. science and the humanities) get credit for teaching it?
Then again, how can we afford not to be teaching such courses? How can we afford not to make it possible for every student who wants to take such a course to have the opportunity?
It's so common, so easy to say that Americans don't have the education it takes to understand the urgency of climate change. But are we in higher education doing what we can? Are we providing an education that helps graduates understand pressing problems?
Here is one course, available as a podcast, which has a multidisciplinary approach to climate change.
And here's an interesting blog I just happened across which examines the psychology of climate change denial.
