Over the last twenty years, the idea that climate change – and global environmental change more generally – is fundamentally a moral challenge has become mainstream. But most have supposed that the challenge is one of acting morally, rather than to our morality itself. Dale Jamieson is a notable exception to this trend. From the earliest days of climate ethics, he has argued that successfully addressing the problem will involve a fundamental paradigm shift in ethics.

In general, Jamieson believes that our current values evolved relatively recently in “low-population-density and low-technology societies, with seemingly unlimited access to land and other resources,” and so are ill-suited to a globalized world. More specifically, he asserts that these values include as a central component an account of responsibility which “presupposes that harms and their causes are individual, that they can be readily identified, and that they are local in time and space.” But, he claims, global environmental problems such as climate change fit none of these criteria, so that a new value system is needed, one which addresses “fundamental questions” about “how we ought to live, what kinds of societies we want, and how we should relate to nature and other forms of life.”
