FWIW, [I heard that] arid ecosystems might arise from cooler and drier climate, not only warmer and drier ones. Thus, if global warming makes Gulf Stream disappear and it leads to cooling of some areas it used to affect, they may become arid geologically soon. But I am not an expert, this is just how I imagine it could happen.
I think that in some parts of the world, for example Maritime Antarctica, it will plausibly grow wetter, and in others, like Europe, drier. On average.

So would you find the reverse, i.e., climates becoming wetter due to global warming, equally plausible?
