The question of whether or not this type of intervention will be necessary comes down to the specifics of various climate tipping points.
There's evidence that we've already crossed a tipping point with regards to methane release (https://www.nature.com/articles/s41467-022-28989-z). The loss of arctic sea ice is another important one, as the albedo of the earth decreases as the reflective ice turns into water.
It seems likely to me that some amount of solar geoengineering will be needed to bridge the gap from now until we achieve a carbon drawdown.
