As hurricanes, droughts, floods, and wildfires are increasing in regularity and intensity, climate change can no longer be ignored. Melting permafrost, forest dieback, ocean acidification, and other processes are creating positive feedback loops which could, if not aggressively and quickly addressed, spiral out of control and take global warming past the point of no return. Hothouse Earth examines how science, politics, and social justice must all be part of the equation to counteract climate change.
