A novel novel, got it. I actually thought it was a pretty straightforward read, but to each their own. According to the novel Termination Shock it could just take an eccentric billionaire to launch a geoengineering effort like that (though with some blowback from state actors) - of course there aren't any of those around, so that's clearly fiction...

Just as a digression I thought Ministry for the Future was a far better book than Termination Shock was.

More that it's a weird form of treatise with the mereset semblance of a coherent novel intertwined within it to encourage people to read it.
