Uninhabitable as in unable to support modern civilization and population levels, probably in large part due to agriculture no longer being viable due to lack of water or weather related issues I'd assume.
That doesn't seem like a good assumption. The fossil record shows a lot of plants growing during previous global warm periods, enough to sustain many herbivores.
Yeah, grass and bushes and trees and shrubs can, have, and will continue to grow in any but the most extreme conditions sure and those are going to be fine for herbivores who can digest and extract nutrients from them, but for the food crops that we can eat, they need pretty specific climates for us to successfully cultivate them at the scale needed to sustain sizable populations.
