Debating Climate Ethics by Stephen M. GardinerStephen M. Gardiner and David A. Weisbach present arguments for and against the relevance of ethics to global climate policy. Gardiner argues that climate change is fundamentally an ethical issue, since it is an early instance of a distinctive challenge to ethical action and ethical concerns (such as with justice, rights, political legitimacy, community and humanity's relationship to nature) are at the heart of many of the decisions that need to be made. By contrast, Weisbach argues that existing ethical theories are not well suited to addressing climate change.
