So did the nomadic peoples of that era, drive evil internal combustion engine vehicles, and have evil coal fired power plants?

Sarcasm........

It numbs my mind when I consider how much about this Earth we don't know and probably never will. Entire civilizations rising and falling without much trace gives me a forlorn sense of awe. Any of those civilizations could have had high technology, and we'll never know.

Thanks for yet another brain tickler.

The crocodiles that were ritually mummified in Egypt were always assumed to be Nile Crocodiles but recently it was discovered they were the type of croc that is still found in the few lakes at the southern end of the Sahara. I think the mummy crocs were from 3000 BC which proves that the Sahara was not all desert even at that date.

So I can easily believe that Arabia was the same.

Have the Saudis stopped destroying all their ancient sites? (the ones before MoHAMmed)

The Earth’s climate changes constantly.

The saudis are developing a sun evaporator plant in the red sea which they say will desalinate sea water for $400@acre foot.

That’s impressive. Water from the colorado river to los angeles via the california aquaduct costs 948@acre foot untreated and about 1158 treated.

The world wide revolution begins when desalinated sea water for the deserts is cheap enough for agriculture. That’s around $300@acre foot for all foods except field crops like wheat and corn.

This has been known for a very long time. McCauley mapped the findings of subsurface rivers across the Sahara via ground penetrating radar in 1982.

About 11,000 years ago the one mile deep ice in the Red River Valley-Fargo to Winnipeg was melting. I wonder if both occurrences are related.

It is difficult to image all these climate chances before President Trump was elected.

The article said the lake was massive.

It also said the lake was 1100 square meters which is 1.1 square km.
The see of Galilee is 168 square kilometers.

Is my math wrong?

[Slicksadick]

It was estimated to be 1,100 square meters in size and 42 meters deep. That’s a pond, not a lake.

More climate change thing. Loss of trees and top soils, exposes sand, clays, and other wind-vulnerables . . . that are moved around <— sometimes to great distances.

Happened to the tip of Cape Code, effectively forcing the Pilgrims community from there, to the mainland.

Now, progressives object to climate change.

same with the Sahara desert

[imardmd1]

Must have been massive forestation there that constituted the basis for today’s imbedded oil reserves. Depth of oil drillings? Range?
