Coal, climate, and confusion
Both of these outcomes (the peak and decline of coal production within a few decades, or 4°C of surface warming) would be an unmitigated disaster for human civilization. There’s no doubt about it. Running low on coal would be great for the climate, but would blow up human economies. If we have more coal than we know what to do with, we would blow-up the climate but the coal would help sustain human economies, absent a miraculous breakthrough in renewable energy.
