Teaming up with PBS, National Geographic has created an intriguing four-part documentary series titled "Strange Days on Planet Earth" that is meant to explore a number of events and processes (such as climatic change and invasive species) and their long- and short-term effects across the planet. Hosted by actor Edward Norton, the series producer's have also created this complementary website where interested parties can learn more about these processes. For example, in the "One Degree Factor" section (which explores global climatic change), users can read interviews with experts working in this field and also learn about the relevance of this process to their own lives. The site also contains a nice glossary of terms and a place where individuals can offer their own comments on the program.
