I video-taped and posted all the lectures from my Global Warming class this quarter. The class is part of our core science curriculum for non-science majors at the University of Chicago, and interest has been strong enough that the class has kind of taken over my teaching life. The lectures are based on my textbook, Understanding the Forecast, written for the class a few years ago. The students found it useful, I think, to be able to skip lectures and watch them later, but mostly I taped them for y’all, thinking someone might them useful. cheers, David.
