If you hadn’t heard, despair is old hat. Rather than retreat into the woods, now is the time to think big, to propose visionary policies and platforms. So enter grand proposals like basic income, universal healthcare, and the end of work. Slap big polluters with carbon tax, eradicate tax havens for the rich, and switch to a 100% renewable energy system.

But will these proposals be enough? Humanity is careening toward certain mayhem. In a panic, many progressive commentators and climate scientists, from James Hansen and George Monbiot to, more recently, Eric Holthaus, have argued that these big policy platforms will need to add nuclear power to the list.
