Complete absurdity. By the end of this century we'll have the technology to make carbon capture (and atmospheric carbon targeting more generally) a trivial exercise.
Predictions about what conditions look like in the year 2100 (let alone 2500!) are meaningless because they assume little to no improvement in technology or energy availability.
This is like those articles about how "in 30,000 years humans will evolve to look like goblins because smartphone". It's status quo bias with James Burnham/Ray Kurzweil levels of unprincipled extrapolation.
