This chapter looks into a specific dimension of adaptation to climate change—disaster risks. It reviews the prospects for increases in disaster risk due to climate change and considers arguments that governments have a duty under international law to respond to these increased risks. Climate change greatly accentuates disasters, putting even more stress on disaster response systems. The list of potential disasters is long, and includes heat waves, droughts, crop failures, wildfires, and outbreaks of illness. Besides the direct threats to human life and property, impacts on food supplies could be severe due to pests, water scarcity, diseases, and weather extremes. The chapter also addresses all phases of the disaster cycle: mitigation, emergency response, compensation, and rebuilding, with rebuilding completing the circle by including (or failing to include) mitigation measures to deal with the risk of another disaster event, and discusses how climate change intensifies problems at each stage.
