Completely baffled by the fact that the discourse on geoengineering is so limited, and the little that there is if so astonishingly low quality: mostly flimsily reverse-engineered rationalizations for deep feelings of disgust, political questions about "moral hazard" masquerading as science, and obvious resistance to alternative decarbonization strategies.

That said, while this piece isn't perfect I think it's pretty good

@stephenjudkins Great article. I wish the writer had dug more into the the observation from Pungoyiwi. Who is the "we" here? What groups can give consent to this work? Is the democratically elected body enough? I don't know the details of this community so I don't know, but it's a knotty problem.
@stephenjudkins I think the "magic" that will get geoengineering going is someone convincing some nation that their plan is worth it.
@OneShoup it's the "free rider problem". Its cost rounds down to free so the first one to decide it's worth it to do it is going to have to be actively stopped, and that country is likely to be in a dire position already...
@stephenjudkins Someday someone will come up with a proposal to lower the average summer temperature of Riyadh by 1ÂșC and it will happen.
