Presenting human security perspectives on climate change, this volume raises issues of equity, ethics and environmental justice, as well as our capacity to respond to what is increasingly considered to be the greatest societal challenge for humankind. Written by international experts, it argues that climate change must be viewed as an issue of human security, and not an environmental problem that can be managed in isolation from larger questions concerning development trajectories, and ethical obligations towards the poor and to future generations. The concept of human security offers a new approach to the challenges of climate change, and the responses that could lead to a more equitable and sustainable future. Climate Change, Ethics and Human Security will be of interest to researchers, policy makers, and practitioners concerned with the human dimensions of climate change, as well as to upper-level students in the social sciences and humanities interested in climate change.
