[R]esearchers at MIT have analyzed dust deposited off the coast of west Africa over the last 240,000 years, and found that the Sahara, and North Africa in general, has swung between wet and dry climates every 20,000 years. They say that this climatic pendulum is mainly driven by changes to the Earth's axis as the planet orbits the sun, which in turn affect the distribution of sunlight between seasons—every 20,000 years, the Earth swings from more sunlight in summer to less, and back again.
For North Africa, it is likely that, when the Earth is tilted to receive maximum summer sunlight with each orbit around the sun, this increased solar flux intensifies the region's monsoon activity, which in turn makes for a wetter, "greener" Sahara. When the planet's axis swings toward an angle that reduces the amount of incoming summer sunlight, monsoon activity weakens, producing a drier climate similar to what we see today.
…
Sahara shifts between wet and dry periods every 100,000 years—a geologic beat that scientists have linked to the Earth's ice age cycles, which seem to also come and go every 100,000 years. Layers with a larger fraction of dust seem to coincide with periods when the Earth is covered in ice, whereas less dusty layers appear during interglacial periods, such as today, when ice has largely receded.
McGee says this interpretation of the sediment cores chafes against climate models, which show that Saharan climate should be driven by the region's monsoon season, the strength of which is determined by the tilt of the Earth's axis and the amount of sunlight that can fuel monsoons in the summer.

Ooooh, I could be rich. I just need to put together a movie with 50 non-related emotional appeals and a hockey puck graph (already discredited is okay).

Too many SUV’s back then...

Would you happen to know some related coordinates?
This also lends credence to the theory that the Sphinx is much older than the academic establishment wants you to believe, on the basis of clear evidence of erosion to the sandstone from rainfall.
I saw a program on one of the cable channels (Ntl Geographic or some other) about this topic a couple of years ago.
That’s the original climate change, unassisted by humans.
Makes sense. The US imposed emission controls in the 70s.
This was the first country to do so after all such laws were repealed in 18030 BC.
Your picture didn’t show for some reason.
That’s odd...it shows on my laptop as I type this post.
Here’s the image address...and it’s a working link: https://i.postimg.cc/J4sq2Qb9/Simpsons-Burns-Blocks-Sun.gif
#16 Ask everyone on the earth to run in a certain direction to “correct” the spin of the planet......
Simply fix.
David McGee makes the point that with ice ages, the ocean water is more acidic, thus the layers of samples were etched thinner. The acidity level is often claimed to be linked to a higher dissolved CO2 content. High dissolved gas content is linked to lower water temperatures.
His data indicates that CO2 varies from natural processes sufficiently to influence climate without further intervention by mankind’s activities.
He later wrote "Paths of the Pole," which was a good read.
