Global warming and climate change -- Climate and history -- Darfur: the first modern climate-change conflict -- Conflict, instability and state failure: the climate factor -- Climate change and security. This Aldelphi book identifies priorities for future research on the climate-security nexus. It illustrates the social and security consequences of climate change that will manifest over the next two to three decades regardless of the policies adopted in the next few years to mitigate more severe impacts over the long term. Efficient targeting of the right type of assistance can reduce costs and understanding how and why different societies respond to climate change is one way of making it possible.
