This chapter introduces climate change as a problem of natural resource justice by outlining some real-world examples of resource conflicts that are being generated, or exacerbated, by climate change. It then provides some necessary background for the discussion to follow. The science and predicted impacts of climate change are explained, along with the options for responding to this problem, such as mitigation and adaptation. The chapter then briefly introduces the debate about global justice and climate change, as it has appeared in the political philosophy literature, looking at the human rights approach, the distributive justice approach, and the key methodological distinctions between integrationism and isolationism and ideal versus nonideal theory. After providing further characterization of, and motivation for, the natural resources approach to climate justice that is taken in the work, it concludes with an outline of the chapters to follow.
