I don't like it when people say we're "too late" on global warming either. But the narrative behind that is not physically absurd - as atmospheric CO2 density increases, the temperature rises, which makes in turn causes increased CO2 (increased fires), and this causes a runaway effect resulting in something like Venus.
It's not too late. And even if things become really dire, even apocalyptic, we may as well face it open-eyed and do our best to survive (in earthbound arks) and recover (applying all those science fictional terraforming ideas...to Terra). It seems highly unlikely that we'll survive (Fermi paradox and all) but that shouldn't stop us from giving it the old college try!
No, you're reading too much into "too late" part. We're unable to prevent reaching 3.5 C rise in 25 years and are clearly on track to exceeding it even more. This is the "too late" part.
We're not too late to mitigate the damage from it. And it will be a lot of damage requiring serious ingenuity to thrive under. Perhaps even survive.
Making the problem worse obviously makes it harder.
