OSLO (Reuters) - The once-green Sahara turned to desert over thousands of years rather than in an abrupt shift as previously believed, according to a study on Thursday that may help understanding of future climate changes.

It was all those UFOs of the aliens that helped build the pyramids. The CO2 they spewed was terrible!/SAR. Actually they have known for a long time that Egypt was green and had lots of rain at least 10,000 years ago. The erosion of the sphinx is thought to have been caused by rain, which means they received lots of rain at one time.
I went on a camel trip in southern Algeria back in the 80’s and there were cave drawings there of natives hunting big game, with trees and things like that in the scenes. You could also still find ancient fish hooks in the desert.
Somewhere out there is a ship with the crew still there—bones, chained to their rowing benches. Way out in the desert. Been there a long time.
There is no doubt the Sahara used to be fertile land. I’ve used it as an example of how ridiculous the man-made global warming theory is many times. The climate changes. It always has and always will. It just amazes me that “reporters” can write stories like this and see no conflict in saying that humans are causing change now, but offer a relatively scientific explanation of what caused it 10,000 years ago.
Been reading Clive Cussler?
This is Reuters, after all. One must always consider the source.
BUMP!
Sorry, the cold get colder and the hot get hotter. Oh, and women and minorities hardest hit.
No, just some guy who has hitchhiked across Africa.
Bit of a nit, but galley slaves did not exist except from the 16th to 18th centuries.
In ancient times, let’s assume you had 300 free rowers and 100 sailors and marines on board. In a boarding action you had 400 fighters. If your rowers were slaves and the other guy’s were free, your fighters would be outnumbered 4:1, not to mention the obvious danger of your own rowers turning on you.
During the 16th century cannon became the primary weapon system, and the rowers were demoted to mere propulsion. This was when galley slaves came in. If they’re not going to fight anyway, you might as well use your criminals for something useful.
This wreck is supposedly way before then, back when the Sahara was navigable.
But isn’t this a good thing, the Sahara getting greener? The article has demonstrated one of the benefits of global warming, though that was certainly not their intent (assuming the mechanism is global warming, which I doubt).
But let’s see, when was the Sahara last green? Around the end of the last ice age? So, the Sahara was greener in a cooler world. Hmmm. This impels me to draw the opposite conclusion; the world is now cooling.
“Expanding deserts
The new results suggest that the tropics have expanded by 2 degrees latitude, or 140 miles, over the past 26 years.
“It's a big deal,” said study team member Thomas Reichler, a meteorologist at the University of Utah. “If this is true, it also would mean that subtropical deserts are expanding into heavily populated mid-latitude regions.” “

Global warming isn't science, because it cannot be falsified.
I thought that it snowed in Baghdad for the first time in a hundred years, this year. That doesn’t sound like global warming to me.
Understood. My point was that there were no galley slaves in the ancient world, regardless of what Charlton Heston thought.
Thanks for sharing.
