> We are looking at billions of deaths from climate change if we stopped producing CO2 tomorrow and tens of thousands of years until the climate returns to pre-industrial levels. This seems to me to be the more absurd position. The challenge of “returning the climate to pre-industrial levels” is easily solvable without any magical technology with merely tens of trillions of dollars. Given a few decades additional progress in rocketry, perhaps only a low single digit trillion dollars per decade (indexed to current real value). Assuming a materials science advancement which permits a functional space-elevator, or the ability to do some manufacturing on the moon, it gets significantly cheaper even than that.
