Land use climate bubbles are popping up throughout the nation at an alarming rate, creating an economic crisis that will be more damaging than that of the housing bubble of 2008. The costs to ecosystems and low- and moderate-income households are equally severe. These bubbles, where land and building values are declining, provide extensive, objective evidence that climate change is real and must be dealt with on the ground. And it sidelines the ideological battles over the political response and instead requires us to focus on the practical question: what can we do to respond? Climate action seeks to avoid the harm we can't manage and to manage the harm we can't avoid. Local leaders understand the urgency of the crisis and are highly motivated to learn how to prevent and mitigate its consequences. This book describes how the local land use legal system can leverage state and local assistance to reduce per capita carbon emissions as an important and now recognized component of global efforts to manage climate change. The tools and techniques presented in the book are available to the nation's 40,000 local governments, if led by courageous leaders choosing to succeed in this epic battle.
