This talk will explain why climate change must be understood essentially as a civilization challenging ethical problem, the practical significance for policy of seeing climate change as an ethical issue, the utter failure in the United States and many other parts of the world to discuss climate change as an ethical problem, why ethics and justice have become the central issues in dispute in international climate negotiations, the practical need of nations to take ethics and justice seriously to have any hope of limiting warming to non-catastrophic levels, ethics and justice issues in a new climate treaty to be negotiated in 2015, and a few ideas for turning up the volume on the ethics and justice questions entailed by climate change.
