Well, it's beyond our current comprehension, anyway. Ie, we don't
know all that much in any great scientific sense. Climatic
experiments are few, far between, and generally not scientifically
controlled.
Climate-ecosystem interactions are even more iffy.
For instance, I've read in several locations that the reason the
Sahara is a desert, now, rather than a prairie, is because of
centuries of sheep grazing.
Whether that is right or wrong, I can't say.
I also can't say if the overall climate changes were a factor in that,
caused by that, or completely independent of that. But I think it
behooves the literal terraformer to study these questions very, very
carefully.
Then ask where you're going to put all the displaced people you've
created by flooding coastlines.
