Earth’s largest hot desert, the Sahara, is getting bigger, a new study finds. It is advancing south into more tropical terrain in Sudan and Chad, turning green vegetation dry and soil once used for farming into barren ground in areas that can least afford to lose it.
Yet it is not just the spread of the Sahara that is frightening, the researchers say. It’s the timing: It is happening during the African summer, when there is usually more rain. But the precipitation has dried up, allowing the boundaries of the desert to expand.
The study was published Thursday in the Journal of Climate. The authors said that although their research focused only on the Sahara, it suggests that climate changes also could be causing other hot deserts to expand — with potentially harsh economic and human consequences.
Africa is the continent least responsible for human-caused climate change, but it’s the most vulnerable to its effect because of unique features. It is, for example, a land mass almost evenly divided between the Southern and Northern hemispheres, creating a wide variety of climate zones.
The future implications for countries already affected by lack of rain and drought could be dire, Nigam said. “Water resource planning, water use and long-term planning is important.”

Terrific. More sand!
These green loons can't make up their mind...
But according to the Out of Africa theory, the human species originated in Africa, so if humans have caused climate change then it sounds a lot like karma, beotch.
They kind of give the game away right there. A desert is not necessarily a hot place. A desert is necessarily a dry place. There are cold deserts (the Gobi Desert is pretty cool).
If the Sahara is expanding (which it does periodically) it is because moisture is being locked up somewhere. Historically, the Sahara expands during cooling phases and shrinks during warming phases due to increased rainfall. So, they're basically telling us that the Earth is cooling -- which is actually much worse than warming -- but they contradict their basic message of rising temperatures, rising oceans. That stuff isn't happening.
A large, well established, Canadian lumber camp advertised that they were looking for a good Lumberjack. The very next day, a skinny little man showed up at the camp with his axe, and knocked on the head lumberjacks’ door.
The head lumberjack took one look at the little man and told him to leave. “Just give me a chance to show you what I can do,” said the skinny man.
“Okay, see that giant redwood over there?” said the lumberjack. “Take your axe and go cut it down.”
The skinny man headed for the tree, and in five minutes he was back knocking on the lumberjack’s door.
“I cut the tree down,” said the man. The lumberjack couldn’t believe his eyes and said, “Where did you get the skill to chop down trees like that?”
“In the Sahara Forest,” replied the puny man.
“You mean the Sahara Desert,” said the lumberjack.
The little man laughed and answered back, “Oh sure, that’s what they call it now!”
Not according to Wiki.
Annually, the rain belt across the country moves northward into Sub-Saharan Africa by August, then passes back southward into south-central Africa by March -Todd Mitchell (October 2001). "Africa Rainfall Climatology". University of Washington. Retrieved 2010-01-02.
Temperature also goes up during the summer, oddly enough.
Oh, noes! We’re all gonna die!
Interesting that the person who wrote this is named Darryl Fears ....
so obviously the evil United States must give up its sovereignty, so their can be a one world government, and it must become socialist so it can end capitalism, and give up its wealth to the poor
There was a time when the Sahara didn’t exist at all. It started growing long before the liberals came along with their carbon spewing limousines and private jets.
Tell us, oh mighty global warming “scientists”, by how many degrees the Earth has warmed in the past 100 years?
What? 1.5 degrees Celsius?
That’s it?
So, was it warm 100 years ago?
What, it was very cold? Colder than during the times of the Vikings and Romans? By how much? 3 degrees Celsius?
So in reality folks, we’ve only warmed up half way.

I don’t know what to believe about this kind of crap, but I know one thing for sure: If the Sahara was shrinking then climate scientists would lecture us about the dangers of losing this “once-great desert” and they would blame the shrinkage on anthropogenic climate change...
The Sahara Desert exists due to climate change.

Sahara Desert Greening Due to Climate Change?
James Owen for National Geographic News
July 31, 2009
Desertification, drought, and despair—that’s what global warming has in store for much of Africa. Or so we hear.
Emerging evidence is painting a very different scenario, one in which rising temperatures could benefit millions of Africans in the driest parts of the continent.
Scientists are now seeing signals that the Sahara desert and surrounding regions are greening due to increasing rainfall.
If sustained, these rains could revitalize drought-ravaged regions, reclaiming them for farming communities.
This desert-shrinking trend is supported by climate models, which predict a return to conditions that turned the Sahara into a lush savanna some 12,000 years ago.

One aspect of the encroaching Sahara is know quite well, but few mention it. The UN for years sponsored numerous boreholes in the Sahil whose wells attracted cattle and camels from the surrounding area. They tended to eliminate all vegetation in a circle that could be seen from the air. As the vegetation disappeared the desert encroached.
When I was a kid in the 60s, I read that the Sahara desert was growing every year and had always done so. If it were shrinking, I imagine the same loons would be screeching about global warming being the cause!
