%$*&$%^# Trump!
Wait, what ?
Are you insinuating that climate change has happened before ?
Certainly you could not say it might have something to do with the giant fusion reactor about 8 light seconds away would you ?
PinGGG!..........................
Those Sudanese and their diesel-powered pick-ups.
Red Heiffer!
Maybe the dude he drew it came FROM a place where there were cattle and green pastures?
SUVs created the Sahara Desert!
I KNEW it!
...and much of north America was a shallow sea.
They have found shark skeletons in mammoth cave Arkansas.
Ya, things change.
Damn petroleum powered transportation. :-(
Yes, da Erf’s climate rises and falls by 16 or so degrees every 100 to 120 thousand years over the past 850,000 years that we know of during this three million year ice age. They are known as inter-glacial periods.
No excuse for them not knowing how to swim
The US government must have been in charge of the lush forests back then! What happened?
4000 years ago is 2000 BC. The Egyptians were kind of active about then if I understand correctly. Did they leave anything to indicate a lush green Sahara?
is it just me or does the term “catastrophic” mean exactly what virtually ANYONE says it means, neither more nor less?
How does this ‘reaffirm catastrophic climate change’???
They have seen this confirmed in many ways. among them, are by taking samples off the ocean floor of the Atlantic near the coast of Morocco.
they can date the layers of mud going back many thousands of years. what they see is that roughly before 3500 BC the mud is thick with pollen as you would see coming off North Africa from a green grassy world.
The newer sediments are nearly devoid of pollen as you would see coming off North Africa from the desert.
The transition happened fairly quickly—within just 100 years.
Evil Egyptians, their cattle farts, oil lamps and cooking fires.
It’s all THEIR fault. To hell with natural cycles so long that stoopid people don’t have the brain capacity to grasp the reality.

suv’s were invented far earlier than I had thought!

There is a regular 40,000 year cycle of greening/desertification across Northern Africa associated with precession and other factors. Sometimes these cooincide with other things like Sea level rise due to things like polar cap melting and or volcanos, meteors, position relative to the galactic plane, stuff we cannot control.
