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.
Wikipedia tells us that 12,000 years ago was during the last Ice Age:
The last glacial period, popularly known as the Ice Age, was the most recent glacial period within the current ice age occurring during the last years of the Pleistocene, from approximately 110,000 to 10,000 years agoWikipedia also informs us that during the last Ice Age the Sahara was a larger desert:
During the last glacial period, the Sahara was even bigger than it is today, extending south beyond its current boundaries. The end of the glacial period brought more rain to the Sahara, from about 8000 BC to 6000 BC, perhaps because of low pressure areas over the collapsing ice sheets to the north.
Once the ice sheets were gone, the northern Sahara dried out.Be that as it may, do they acknowledge the "demon" gas ......er...sorry.....plant food, Carbon Dioxide? Atmospheric Plant food, Carbon dioxide has been increasing.....
