LONDON: Contrary to the assumption that would cause an expansion of the world's deserts, some scientists are predicting that water and life may slowly reclaim these arid places.
According to a report by BBC News, the evidence is limited and definitive conclusions are impossible to reach, but recent satellite pictures of North Africa seem to show areas of the Sahara in retreat.
It could be that an increase in rainfall has caused this effect.
The Sahara is experiencing a shift from dryer to wetter conditions, according to Farouk el-Baz, director of the Centre for Remote Sensing at Boston University
If my history serves me well, Egypt was a breadbasket to the Roman Empire.
A liberal and I had an argument about this many years ago. He insisted that it was flat out, with out question totally impossible to make the desert bloom and become productive.
He wasn’t very smart, but he thought he was. You see, he was in college. College is when you know everything there is to know and what you’ve been spoon fed is the absolute truth.
I also seem to recall that up until relatively recently (6,000 - 8,000 years ago) The Sahara was quite lush.
It’s that dastardly gas CO2, doing its nefarious job of encouraging more and faster plant growth. Perhaps helping the planet Earth to self-adapt in advance of a coming mini-ice age in the lower latitudess.
This gas must be found and capped at the source!
I have read a ton on this, specifically the cooling / drying cycle versus the warming / wet cycle. When I read repeatedly that Global Warming will cause deserts to expand I find how ignorant / bias the reporter is or that the scientist that makes the statement has funding issues tied to research (they ignore all the climate records from the last 25,000 years). Each time the globe cools, the deserts expand (very quickly), each time it warms, the deserts shrink. Cold air has very little capacity to hold water (hence Antarctica is essentially a vast desert) and warm air can hold a lot.
In the envirowienies mind, green spreading vegetation replacing desert has to be a bad thing because of the loss of habitat for sand mites. (Or some plant/animal/bug/one celled organism)
Ecosystems must be made static. It’s fun to watch them struggle in a losing battle.
“Hydrocarbons are essential sources of energy to sustain and extend prosperity. This is especially true of the developing nations, where available capital and technology are insufficient to meet rapidly increasing energy needs without extensive use of hydrocarbon fuels. If, through misunderstanding of the underlying science and through misguided public fear and hysteria, mankind significantly rations and restricts the use of hydrocarbons, the worldwide increase in prosperity will stop. The result would be vast human suffering and the loss of hundreds of millions of human lives. Moreover, the prosperity of those in the developed countries would be greatly reduced.”
If we don’t change our ways and spend trillions of dollars, millions of acres of desert wasteland could become sustainable agriculture within a decade. Please give generously.
Is there more rain due to warming and melting of ice?
stuartcr: “Is there more rain due to warming and melting of ice?” ?????
Ice has not melted!>>>>
Sea Ice - June 2009
The global sea ice anomaly in June 2009 remained positive. Over the 1979-2009 period, there is zero trend in global sea ice anomaly, with a SH increasing trend offsetting a NH decreasing trend. June 2009 NH anomaly was not remarkable.

Well the Nile Delta still is a very lush semi-tropical environment.
