This book describes the long-term four billion-year context of anthropogenic climate change, and seeks to explain our inability to respond positively to its challenges. It argues that the availability of energy and the consequential capacity to do work and exert power has, over this time, defined the trajectory of life on planet Earth as well as many of its physiochemical characteristics. Six major historic energy revolutions are recognised - energising of the first living cell; harvesting the Sun's energy; emergence of complex eukaryotic cells; hominid use of fire/cooking for brains not brawn; agriculture, more food and urban life; fossil fuel bonanza and the industrial revolution - and we are now in the midst of the seventh revolution, responding albeit reluctantly to anthropogenic global climate change.
