Ninety-nine percent of scientists agree that the human race is a hot mess. Climate change is the evidence. Over the past couple of centuries, we’ve released so much CO2 and other greenhouse gases into the atmosphere that we’ve literally turned up the heat on our planet. Mankind’s most lasting mark on Planet Earth—even after we’re long gone—may be the itchy burn of global warming. As the temperature rises, expect mass migration like the world has never seen, sending whole civilizations across the globe in search of safety. Extreme weather events including torrential hurricanes, persistent drought, and unquenchable wildfires will batter communities and natural habitats. Decades of a polluting will bear the fruit of a toxic planet. And, last but not least, social turmoil and global warfare will break out on account of the scarcity of resources as benign as water and food. The consequences of unstoppable climate change will bring civilization to the boiling point.
