We are the last individuals of our species on Earth. How shall we respond? How shall we act? If industrial civilization is maintained, climate change will cause human extinction in the near term. If industrial civilization falls, sufficient ionizing radiation will be released from the world's nuclear power plants to cause human extinction in the near term. In the wake of this horrific conclusion, conservation biologist Guy McPherson proposes we act with compassion, courage, and creativity. He suggests we act with the kind of empathy for which humans are renowned. In other words, he suggests we act with decency toward the humans and other organisms with which we share this beautiful planet. Going Dark is the story of one scientist's response to the horrors we face. It is a deeply personal narrative infused with abundant evidence to support its terrifying claims. In the words of syndicated cartoonist David Fitzsimmons, McPherson's "approach is disarming and his message is both life-changing and convincingly alarming. A blend of Paul Revere with Rachel Carson, Guy McPherson is a significant voice of rational conscience nudging in the wilderness. Fierce as Ed Abbey, and equally prophetic, Professor McPherson is a modern-day John Muir with a global perspective. Beyond the warnings is a body of thoughtful and pragmatic real world ideas.
