3. What about nuclear? I haven’t said much about nuclear (fission). That’s because, while in principle it ought to be an enormous help, there’s a set of problems with it that I just don’t know much about how to solve.

Good news: there’s a lot of them, many seem quite promising. If we can do scalable NET at $10 per tonne, then we can get to net zero emissions at about the same price as for the Clean Air Act (& quickly reduce it). http://cognitivemedium.com/dac-notes pic.twitter.com/1HPHeVb9Qy

The bad news: we don’t have cheap, scalable NETs :-) I do think this is a wonderful research opportunity, though, and my impression is that it’s very under-invested in.

I know some people don’t like the last, but think it’s good when groups of people profit from providing an enormous social good, like scalable clean energy, or carbon removal. That's capitalism operating as it should, to serve the social good. I hope it does here.

Of course, the flip side: there’s damage already being done, and likely to be incredible damage done.

We don’t yet have institutions or norms that enable us to deal with problems where inaction over the next few decades may cause much of an ice sheet to melt a century or two from now. I hope we can develop such institutions and norms!
