When I was studying climatology, I wondered if an increased evening out of global temperatures (with higher latitudes warming disproportionately more than lower) would lead to a kind of lethargy in weather systems, since it is ultimately temperature differentials that are the driving force to their movement. So systems that bring rain to the coast might be less likely to wander inland, for example. That would then intensify the continental effect and make interiors more prone to drought.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Wasnt that the basis for Interstellar?
Oh hmm… I thought they were having some sort of problem with a blight that was wiping out all the commercial crops one-by-one until only corn was left. And then the NASA researchers realized even corn was on in trouble. But there was a lot going on in that movie that was hard to follow, so I'm not sure. Maybe there was a climate angle?
Going back to the lethargy idea, one could also surmise that when the rain does work its way inland, you could get more than you bargained for because the system will stall again and dump on one spot rather than moving on. At least that sort of tracks with what we've been seeing.
Might have confused it with Grapes of Wrath and came out with a weird conclusuon, been a while on both
yeah, not surprised. just bc it can hold more moisture, doesn't mean there is a increased rate of vaporization to fill the new capacity.
my guess is that the rate of vaporization is dropping in the drier regions.
I'd also argue that what makes a desert a desert still applies in most cases. Often times a desert is in the "rain shadow" of a different geological feature such as mountains. There may be more moisture in the atmosphere, but the same traps are preventing it from moving into those areas and keeping it in the same areas as before.
In addition, deserts being harsh means more work for other plants that raise/lower abeido to adapt and move in. More water doesn't mean healthier soil immediately. It'll take generations of steps.
