Climate change is not simply a problem for future generations. Hurricanes, droughts, floods, and wildfires are increasing in regularity and intensity. Melting permafrost, forest dieback, ocean acidification, and other processes are creating feedback loops which could, if not aggressively and quickly addressed, spiral out of control and take global warming past the point of no return. Scientists predict severe weather conditions will disrupt agriculture, causing a global food shortage.Scientists and engineers are working around the clock on renewable, green energy technology and geoengineering techniques. But it is not enough. Humanity needs to be doing more to save the planet from certain destruction. Hothouse Earth examines how science, politics, and social justice must all be part of the equation to counteract climate change.
