In introducing the sociogenic approach to climate change, Harvey re-examines history through the lens of climate change, re-writing the climate impact of the British industrial revolution; US settler colonialism; slavery and Native American genocides; the electrification of societies and infrastructures for fossil-fuelled transportation; and changes in our eating habits. In the big historical picture, different societies and political economies have both created an unequal world and so continue to make an unequal contribution to climate change. This can only be understood by showing how societies have come to distinctively exploit planetary resources in different ways. Societies create the crisis and have to be politically involved in addressing the crisis.
