Great post, but I would add a point.

Since we already triggered feedback loops (eg. thawing of permafrost) we probably need to go carbon negative for a while to stop said phenomena. This means over-provisioning our clean energy supply to power CO2 scrubbers or some similar tech.

I fear that, considering how hard is to get the world to agree to net 0 emissions, the negative emissions discussion will probably be a bloodbath.
