This new report from researchers at the University of Maryland, College Park, makes a harsher prediction than previous studies that estimate expansions at about 10%.
"Our best guess is that human-induced global warming is going to dry out much of the arid lands in Africa's Sahel region, areas around the Mediterranean Sea, the fringes of China's Gobi desert, parts of South America and southwestern North America.
Moderate estimates by the Intergovernmental Panel on Climate Change (IPCC) predict that deserts will expand 10 percent worldwide by the year 2100. But it could be much worse."
