The author of the new textbook we have adopted for Global Climate Change this semester, David Archer, is featured on the New York Times blog discussing the release of his videos that go along with the book so anyone can learn about climate change online. Although I'm sure these are extremely well done, I can't help but recommend that you simply take my MTR 1600 course instead!
I can't really comment on the book at the moment, as I am just diving into the depths of it this week, trying to change over old presentations to follow his set up. I hope it is worth the switch from Kump et al. "The Earth System," which is a fantastic book, but just a little too much depth for the amount of time we have to cover the pure science in my course.
