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.
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.
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.
