But I've long had the pet theory that the Green Sahara is the origin of the Eden Myth.
Homo Sapiens origin, lush vegetation, turns to dessert for some reason beyond our comprehension...
Sahara could be green again in the future once the East African Rift becomes a new ocean 10 million years from now.
Would it though? The trade winds converge over central Africa, which is already quite lush, so presumably any extra moisture would just be deposited there instead of a few thousand miles to the north.
When was this research established? I've heard about this a few years ago but when was it found that Arabia was green historically?
This specific research tightens up the timing and driving factors for the specific Sahara region (Libya, Egypt, Sudan) and doesn't relate to the Arabian Peninsula which is an almost seperate landmass more than three quarters surrounded by sea water.
On that landmass the Arabia Felix region (modern Yeman (mostly)) is known to have been greener in the past.
I think it was in Michael Palin's show Sahara, he's talking to some locals living in a village in the middle of the desert, and while I'm wondering why anyone would ever settle out there, the person being interviewed relayed that many more people used to live there before it became a desert. It wasn't that they moved out there, they were all that was left. Kind of post-apocalyptic. Edit: found the mention, he's talki…
So with the co2 forcing function, is it possible that Canada be glaciated again And that the Sahara be green? That would fly in the face of conventional thinking which is that Canada will be temperate and the Sahara will be more arid.

Great reminder to all that we know we are effectively killing Lake Chad, but there's not much anyone is really doing about it. [0] https://en.wikipedia.org/wiki/Lake_Chad
I'm not a historian, archeologist, or any sort of relevant expert. But I've long had the pet theory that the Green Sahara is the origin of the Eden Myth. Homo Sapiens origin, lush vegetation, turns to dessert for some reason beyond our comprehension...
Somewhat off topic, but if anyone's read Sand County Almanac by Aldo Leopold, he talks about how the American Southwest, specifically Arizona, used to be green. Apparently the familiar reddish brown resulted from human impact
What’s the proposed mechanism for that? It doesn’t seem plausible to me on the surface.
There is some stuff along route 66 that suggests the desert was there longer than humans though. One example is the crater they used for moon landing training. It’s basically undisturbed, and is extremely old.

Carbon emissions ACCELERATED climate change. Climate change is natural. It's the ACCELERATED change that is the problem. Not enough time for species to adjust.
Your argument is similar to “Everyone would have died anyway; this thermonuclear winter just sped it up. Totally not humanity’s fault we live in a bunker.”
