If humans gave up on geoengineering after 50 years, it could be far worse than if we had done nothing at all

Yeah, it’s a problem. Nuclear waste is kind of a separate category, though. We didn’t hit that anywhere near as hard as coal/oil. That could just be an issue of scale. I don’t honestly know if that could have been satisfactorily addressed if nuclear power had been more widespread.

But the climate is going to change whether we stop industrial carbon or not. At this point, it’s not looking like we have many choices available to us.

I’ll vote 100% for this. But this necessity isn’t reflected in any reality currently on the table.

You’re a scientist. I’m not, but I’ve done the same thing looking at the primary literature. I see where everything is heading, and it might be our only shot at surviving it is some form of geoengineering. Maybe not.

If not, we had a good run, up until the end, anyway. The anthropogene will be pretty short, but we left a lot of crap in the oceans, so maybe that’s for the best. Life will go on, but we won’t necessarily be among its participants.

That “Man After Man” book probably won’t pan out, anyway.
