Nowhere else in the world is so regularly ravaged by infernos of the intensity, scale and destructive force of the Australian bushfire. As our population grows and spreads and as the effects of climate change are felt, the danger to loss of life and property escalates. What do we know about bushfires and how can we prevent their devastating consequences? Not surprisingly, Australia is a world leader in fire research and the complex and technologically sophisticated job of fire fighting and prevention. Inside The Inferno takes us into the terrifying heart of major fire events, unfolding the research that explains how fires start, grow and change; and how we predict them, prevent them, fight them and hopefully survive these violent natural disasters.
