Arx, I'd be careful leaning too heavily into the "models say it will be drier, so it will be drier" particularly for things like the Sahara when they struggle to replicate past periods we know were wetter and a few need somewhat absurd precipitation adjustments to reproduce observed vegetation as inferred from sediments and so forth:
https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2017GL073740Plus focusing on the Sahara when I'm talking about the whole planet is kinda talking past each other. We know that it was much drier and more arid and deserts expanded enormously during the coldest parts of the last ice age. While there are orbital/insolation effects that trigger the transitions into/out of ice ages the local changes due to ice sheets and cooler air are also known factors.
I'll be much happier at the projections of a model which can reliably backcast known conditions, and I'll be more concerned if such a model does somehow predict both warmer temperatures everywhere AND more arid conditions in more places than we have today.
I remain dubious at such a thing happening because the physical effects required are... improbable to say the least, and generally the idea that you randomly ended up perched on top of a peak rather than slipping down into a surrounding well is one that should raise questions. So if we're currently at a precipitation maxima under current conditions and temperature variances either way will reduce precipitation regardless how much said conditions diverge then THAT needs explanation, an extraordinary one at that, given how remarkably unlikely such a state should be.
Like we're talking "oh shit, we're in a simulation and they didn't plot sensible variations beyond a certain duration because they're just gonna reset back to a particular date anyways" type of explanations here.
