Default Sahara Desert Greening Due to Climate Change?

Sahara Desert Greening Due to Climate Change?

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.

Green Shoots

The green shoots of recovery are showing up on satellite images of regions including the Sahel, a semi-desert zone bordering the Sahara to the south that stretches some 2,400 miles (3,860 kilometers).

Images taken between 1982 and 2002 revealed extensive regreening throughout the Sahel, according to a new study in the journal Biogeosciences.

The study suggests huge increases in vegetation in areas including central Chad and western Sudan.
Is this happening in other arid regions of the world too?

Interesting. Looking forward to reading the paper (can't seem to find it yet) - Martin Claussen is a good guy.

The greening of the Sahel has been known about for a while now. It's not front page news, like how "possibly" millions will die from global warming.
