Climate change proponents are often accused of using scare tactics. Maybe there’s some truth to that. In a single cubic foot of earth there are billions of living things, so okay, we aren’t likely to kill the planet. But we are changing the planet. What began as a cheap source of energy has fired up a whole chain reaction of unintended consequences. We know now what we didn’t know then. Rapidly dumping billions of tons of carbon emissions into the air is a climate changer. Maybe we won’t kill the planet, but we’re definitely inflicting a lot of collateral damage.
