In the absence of a federal legislation directing government to adapt to the unavoidable effects of climate change, the Obama administration has put its faith in existing environmental laws like the Clean Air Act (“CAA”), the Endangered Species Act (“ESA”), and the National Environmental Policy Act (“NEPA”). But often federal objectives focus only on reducing greenhouse gases—what experts call “mitigation”—and neglect strategies for coping with the climate disruptions that we cannot avoid—otherwise known as “adaptation.” Where the federal policy falls short, states are beginning to experiment on their own with climate adaptation strategies. This essay examines both approaches, mitigation and adaptation, and proposes actions that communities can take to become more resilient on a warming planet.
