NASA's latest visualisation tracks fires across the planet and their effect on vegetation as they go. It's frightening and yet hypnotic viewing.
Imagine, if you will, a terribly serious documentary about fire. Inevitably, a stern toned man would pipe up about how fire was man's first tool, and at the same time one of his deadliest foes. Fires can be warming, but they can also be devastating, and Nasa's visualisation of the world's fires makes for compelling but disturbing viewing.
Australia has more than its share of serious fires, but Africa's the most mesmerising; the scale of some of those fires must be massive.
