Sahara Desert Greening Due to Climate Change?
Scientists are seeing signals that the Sahara desert and surrounding regions are greening due to increasing rainfall. If sustained, these rains could revitalize drought-ravaged regions, allowing farming communities to return. This 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.
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. Images taken between 1982 and 2002 large regreening throughout the Sahel.The study suggests huge increases in vegetation in areas including central Chad and western Sudan
