A politician, Gore was one of the first to draw popular attention to climate change. He supplemented the best-selling book with a film and DVD with the same title. Ten years later, recognizing that in spite of its wide circulation, his first effort had not had sufficient impact on governmental or social policies, Gore issued An inconvenient sequel, truth to power. Your action handbook to learn the science, find your voice and help solve the climate crisis. New York: Rodale Press, 2017. In spite of the social urgency expressed in the sequel, no film or DVD version was produced, and the impact of the sequel was limited.
