Burning fossil fuels, cutting down forests, raising livestock, making cement, and using synthetic fertilizers are among the actions that have increased the amount of heat-trapping gases in the atmosphere to the point that the planet’s basic functions are coming undone. These impacts are not linear — they accelerate with more warming.
