The entire working mechanism of climate change is increased water in the atmosphere. That's why it's getting warmer. CO2 and other gases only accelerate that process a little bit (but as we're at the end of the warming cycle, "a little bit" should be interpreted as accelerating warming by a little bit, if you count the number of years it brings warming forward, that's a lot. Probably a millennium, maybe more). Obviously it also makes things warmer and generally wetter, thereby making very large areas livable that weren't livable before.

The entire inside of India used to be desert. That desert did not just reduce in size, it split in three pieces and two of them shrunk to zero, and even the third is turning green. The Sahara too is less than half the size it used to be.

Also, large regions closer to the poles are becoming warmer ... and that means livable.

And yes, elsewhere deserts are becoming worse, for instance in Spain.

It doesn't really matter though, as humans are not exactly short on space, and this means we'll need to move large populations in the next century.
