A world of hotter temperatures, more floods and droughts, and more disasters is approaching. We are in a new geological epoch-the Anthropocene. Humans have not only changed the natural environment on the surface, but also affected oceans, forests, rivers, and the terrain of more than half of the earth's surface from the inside out. We even genetically change the types of plants and animals. Humanity is getting stronger and stronger, but losing control on more levels. We'll read about the most cutting-edge, wildest plans to combat global warming: launching tiny diamonds or other particles into the stratosphere-"like sprinkling the world with pixie dust"-to simulate what would happen after a volcanic eruption, using reflective particles to reduce the temperature of the sun as it reaches the ground. Solar geoengineering works quickly, but it also comes with unknown side effects. What researchers are sure of is that this will change the look of the sky, and the new "sky blue" will be white. This time, Colbert will examine how humans, sometimes bravely and sometimes foolishly, change nature in order to control it, how they destroy within a few decades things that took millions of years to create, and how they try to undo the damage they have caused by interfering with nature.
