Mitigation polices, the subject of the last chapter, are important tools for reducing emissions. Mitigation of emissions is absolutely necessary, but not sufficient. As we reach tipping points, certain impacts of climate change are becoming unavoidable. While the degree of damage associated with those impacts can, in part, be mitigated with carbon pricing, not all impacts are preventable. Climate adaptation, the subject of this chapter, is an inevitable component of the mix of policies needed to manage the risks from climate modification.
