Warmist Bill McKibben: In an attempt to prevent bad weather, let's do a lot more manual farm labor, and let's try to power the country using rooftop solar panels

We might decide that the human enterprise (at least in the west) has got big enough, that our appetites need not to grow, but to shrink a little, in order to provide us more margin. What would that mean? Buses and bikes and trains, not SUVs. Local food, with more people on the farm so that muscles replace some of the oil.
...
Imagine, for instance, a nation that got most of its power from rooftop solar panels knitted together in a vast distributed grid. It would take investment to get there – we'd have to divert money from other tasks, slowing some kinds of growth, because solar power is currently more expensive than coal power. We might not have constant access to unlimited power at every second of every day. In the end, though, you'd have not only less carbon in the atmosphere, but also a country far less failure-prone. The solar panels on my roof could break tonight – and I'd have a problem if they did – but it wouldn't ramify into rolling blackouts across the continent (and no one would need to stand in my driveway with a Geiger counter). Such changes wouldn't make the world safe: climatologists promise us we've already put enough carbon out there to raise our planet's temperature two degrees in the decades to come, which will make for a miserably difficult century. But they also promise that if we don't stop burning coal and oil, that number will double, and miserable will become impossible.
