Twenty-five years of human effort have failed even to slow climate change, let alone reverse it. Climate Insurgency lays out a strategy for protecting the earth s climate: a global nonviolent constitutional insurgency. This short book starts with a brief history of official climate protection efforts from above and non-governmental ones from below that explains why climate protection has failed so far. Then, it proposes a global nonviolent insurgency for climate protection to overcome that failure. Historian and longtime activist Jeremy Brecher presents a public trust doctrine that can legitimate global climate insurgency in national and international law. He shows how to make national economies climate-safe and points the way toward justly distributing the global costs and benefits of climate protection. In addition, he lays out a new strategy to make governments and economies meet their obligations to protect the climate.
