Dear deniers of human-caused climate change: Have you looked at our air lately? Have you tasted it? Has it gotten stuck in your throat and made you cough, or made your eyes water?
Guess what? Nature didn't do it. Those noxious vapors and toxic particles are virtually 100 percent human-caused!
Multiply the visible toxic emissions by the amounts emitted daily around the world by cars and factories, power plants and furnaces, fires methane, chlorofluorocarbons and all other man-made pollutants containing sulfur and nitrogen dioxides and you begin to see the problem. These contaminants fall to earth as acid rain, poisoning soil, plants and water.
