If you’ve seen Al Gore’s film An Inconvenient Truth, then you’re probably familiar with the concept of global unrest spurred on by climate change. In his film, he talked about these issues as being something that could happen in the future, but as we’re seeing around the world today, these events are already happening. As climate change is making access to resources more and more scarce, people around the globe are becoming scared, and sometimes violent. Mike Papantonio talks about how this is happening, and what we can do, with Christian Parenti, author of the new book “Tropic of Chaos: climate Change and the New Geography of Violence.”
