It’s nearly ten years since Kevin Rudd said climate change was the great moral challenge of our time. While three quarters of Australians now believe climate change is happening, some still aren’t sure whether it’s just a natural cycle or whether it’s caused by human activity like burning coal.

Nobel Prize winner Peter Doherty says our lack of understanding of the science comes down to the knowledge wars being run by vested interests, who stand to lose if we take meaningful action on climate change . He’s urging you to inform yourself and his book, the Knowledge Wars, is a guide to navigating what is misinformation and what is real.
