This visual primer sheds light on climate change on the basis of reportage, case studies, and striking image sequences. Presented alongside chapters on the history of the earth and of climate and on the climate engines (solar energy, greenhouse gases, and global warming) are both the consequences of climate change and the political strategies designed to combat it. In the foreground are existential problems as formulated by the Millennium Developmental Goals: poverty and hunger, health and underdevelopment, but also the interdependency between climate change, economics, and politics. Unavoidable in this context as well are problems related to migration, megacities, and ethical questions of human rights, equity, and solidarity. For Climate's Sake! addresses these questions rationally, at the same time evoking an emotional response.
