I’ve already blogged about climate change videos but wanted to post this film by Leo Murray separately because it really is in a class of its own. It’s a beautifully animated, thought-provoking film, and one which I think students will enjoy watching. You can find the HD version here. There is some good science in the film, with clear explanations of mechanisms that cause climate change and of how we might reach a “tipping point”. (Leo provides a copy of the script, including references here.) However, it is an unashamedly political film and you may want to discuss this with your students. It contains some scary ideas, so I wouldn’t recommend showing it to any classes below Year 9. As other people have commented, the fear of nuclear armageddon with which my generation grew up has been replaced with nightmares of end-of-the-world scenarios caused by climate change. This film may add to those nightmares, but that might not be a bad thing…
