This is such a small take.

Climate change can absolutely be reversed by sufficiently determined technological and industrial civilization.

The reason most climate activists don’t acknowledge that is because they don’t want it to be true. They prefer being noble doomsayers before the “ignorant sheep.”

There are (expensive) geoengineering projects that would give humans direct control over global temperature.

It's also crystal clear geoengineering will ultimately be how the problem is addressed. Everything else is a distraction given the reality of how people and societies work.

We can't simply do many order of magnitudes easier task now (reduce carbon emissions). How exactly do you suggest we do this task you suggest later?

What it would take to move the Earth slightly further away from the sun, to offset that 4º ~ 8º spike?

Maybe climate change could be by a sufficiently determined technological and industrial civilization, if there was some such thing. Climate change could also be solved by a magical flying rabbit, if there was some such thing.

[ByteJockey]

They aren't talking about sufficiently advanced technology (magic). They're talking about things we can already do, but have serious trade offs.

The most common suggestion is to add particles to the atmosphere that reflect sunlight. I think sulfur was first proposed, but I think study of calcium carbonate has been ongoing to avoid the ocean acidification issues that sulfur presents.

[Fricken]

The imaginary part is sufficient determination.

[ByteJockey]

My understanding is that the costs are low enough to be done by a single country unilaterally.

At least at first. If we start doing it, and don't reform our ways, it gets progressively more expensive.

Probably a nice stop gap if we ever get our shit together, but are staring down some really bad after effects.

This is obviously false. Please take this nonense elsewhere.

I agree with the rest of your comment more than with the person you replied to, like, of course we can have a major effect on the climate if we see the need to (if we indeed see 8°C warming and traditional food supplies failing, suddenly the powers of this world will see ways to do something about it that they aren't doing today) and it doesn't automatically mean an imminent end to history like GP claimed. I just don't get why you had to add the cited part. We're all on the same team.
