Yes, as a former (regrettably) anti nuke activist, go nuclear. But ban coal now. And plan to phase out existing coal plants. It's our only hope. With coal, the world is very much doomed.

Sigh. In an energy-short world, phasing out coal plants is just not going to happen. Especially with high-investment replacements.

If we are only concerned with CO2 then stopping new construction (without sequestration) within a decade and then gradually decommissioning over the next half century might be acceptable from a climate change point of view i.e. it would keep us under 450ppmv CO2 concentration.

Excellent idea.

Free also.
