Forests, wildlife, property and often human life is endangered when fires break out. Fires strike when the air is hot and the land is dry – and spread when high winds fan the flames. Lightening is the major source of naturally occurring fires. This episode looks at the California fires of 2007, the Los Alamos Research Laboratory super computer called "Blue Mountain" that simulated unfolding weather patterns, as well as the Fire Camera system in NSW, Australia, and the fire festival in Spain.
