There’s a joke that goes around the PNW that goes:

“A logger was being interviewed for a job as a logger by a large tree farm. He was asked where his last job was. He replied that he was a logger in Saudi Arabia. The interviewer laughed and said ‘there are no trees in Saudi Arabia, it’s a desert’. The logger agreed and said ‘yeah, - now!”

PNW humor ...

Veeeery interesting!

Pity we aren’t heading for global warming for the next few decades. Yesterday’s solar flux values were:

Flux Density Values in sfu for 23:00 on 2008:10:02

Julian Day Number : 2454742.447

Carrington Rotation Number : 2075.228

Observed Flux Density : 0065.6

Flux Density Adjusted for 1 A.U. : 0065.7

URSI Series D Flux, Adj. x 0.9 : 0059.1

From the linked article:

The green Sahara episodes correspond with the changing direction of the earth’s rotational axis that regulates the solar energy in the tropical Atlantic Ocean.

I wonder if a scientific consensus exits regarding these geophysical data? Chances are there are many peer-reviewed papers.

Can temperate conditions in the Sahara actually be the more natural (i.e. the north polar glacier cap is minimal)? As many old sci-fi tales ended, I shall do the same. "Time will tell."

There’s strong evidence that cattle and dogs were domesticated in the Sahara during its most recent greening, and that the most recent desertification was the impetus behind the urbanisation of the Nile valley.

I’ve thought that the rapidity of the most recent desertification, which may have unfolded in less than a century, might have been the basis of the story of the expulsion from the garden of Eden, with its missing rivers and cherubim with swords of fire.

There is an area in western Egypt that is below sea level known as the Qattara Depression (18,000 m2 and -133 meters). If we were really worried about lowering the sea, how about digging a massive canal, wide enough and deep enough for commercial shipping / ports, etc from these low lands to the Mediterranean.

This would accomplish:
1) more moisture going westward from evaporation and thus creating a green belt area to the west of the depression.
2) lower the sea level abit
3) create the possibility of an inland, central Africa port and thus improve the economic conditions for western Egypt,

Computer model simulations for the future suggest an expansion of the vegetation cover in the Sahara Desert if human-driven climate change leads to aggressive global warming.

So - has Buffet been buying real estate in the Sahara?
