That's not how that works. The Sahara savannah is tied to the rotation of the earth on its axis. That takes roughly 23,000 years. The period of time between savannah periods is about 13,000 years and the last one ended roughly 6,000-7,000 years ago. The next one will start in roughly 6,0000-7,000 more years.

This is oversimplified, by a lot. There are many factors impacting Africa's aridity, including the current glaciation cycle, sea levels as a result thereof, the AMOC, etc.

... Are you aware of any study or perhaps graphic or map based on a studies that... actually tries to model the effects of an AMOC shutdown?

Or maybe 'signifcant weakening' or 'decoherence' would be a more accurate way to out it?

Because I loosely keep up with Paul Beckwith's roughly weekly videos and uh... the SMOC ain't doin so great, and like, currently, and in the last month or two... well, the artctic polar vortex has ... more or less been destabilizing... to a rather extreme amount...

Pretty sure that the sahara is classified as a mid latitude desert, similar to the Arabian, the atacama or the great Sandy desert in Australia which are influenced by the Hadley Cells

Well you were certainly happy to discredit it. If you aren't willing to explain why, dont speak

Just like you explained the full thing? That type of "not speaking?"

I simplified things. You added no concrete additional context.
