Climate Change, Human Rights, and Moral Thresholds

Abstract

It is widely recognized that anthropogenic climate change will have harmful effects on many human beings and in particular on the most disadvantaged. In particular, it is projected to result in flooding, heat stress, food insecurity, drought, and increased exposure to waterborne and vector-borne diseases. Various different normative frameworks have been employed to think about climate change. Some, for example, apply cost-benefit analysis to climate change. The Stern Review provides a good example of this approach. It proceeds by comparing the costs (and any benefits) associated with anthropogenic climate change with the costs and any benefits of a program for combating climate change. On this basis, it argues that an aggressive policy of mitigation and adaptation is justified. Whereas the costs of combating climate change, according to Stern, are quite low, the costs of “business of usual” would be considerable. Other analysts adopt a second perspective and conceive of climate change in terms of its impact on security. For example, the High Representative and the European Commission to the European Council issued a statement on Climate Change and International Security, which argues that climate change is “a threat multiplier which exacerbates existing trends, tensions and instability.” It argues that climate change will contribute to the following kinds of insecurities: tensions over scarce resources; land loss and border disputes; conflicts over energy sources; conflict prompted by migration; and tensions between those whose emissions caused climate change and those who will suffer the consequences of climate change. In addition to the “economic” approach and “security-based” approach, some adopt a third different perspective, according to which the natural world has intrinsic value. This ecological approach condemns human-induced climate change because it is an instance of humanity’s domination and destruction of the natural world. For all of their merits, these three perspectives omit an important consideration: the impact of climate change on persons’ fundamental human rights. In this chapter, I argue that it is appropriate to analyze climate change in terms of its impact on human rights.
