I think we're staring ourselves blind, straining to see any possible high-tech solution that will solve climate change neatly, easily and without any significant sacrifices.

The problem is not technological. It is political and societal, and those cannot be solved by technology.

At this point, even trying to mitigate the consequences of climate change will take large-scale mobilization, on a scale we have never seen before, much larger than the wartime mobilizations of WW2. Considering our current stumbling response to a global pandemic, with possible consequences much lesser than what climate change will bring, I'm sorry to say that the outlook is quite grim.

We have act as humanity collectively, not as individual bickering nations.

I’m rather more optimistic; WW2 was an extremely large mobilisation, and I think this could have been done at the scale of the moon landings a decade ago, but now the tech is cheap enough for people to make a profit while saving the environment.
