Stewardship is hard. Like, really, really hard. And let’s face it: Americans have to have a gun pointed at them in order to deal with anything this hard.

Ken Caldiera at the Carnegie Institution for Science was approached by a science writer with a relatively straightforward question: if we got off our coal-burning, wasteful, polluting methods of energy production, how long before we felt the benefits of that change? The numbers suck.

In order to do anything that might be considered “repairing” the damage done by fossil fuels, we would basically need to completely eradicate coal burning technologies. And if we did that, we might start seeing the benefits somewhere around half a century from now.
