WORLD | Carbon goes green | Daniel James Devine | Nov. 30, 2013: "To a plant, carbon dioxide is food. But the gas has a counterintuitive effect on a plant’s metabolism: The more CO2 in the air, the less water a leaf needs."
"researchers estimated that warm, dry areas were 11 percent greener than they would have been had CO2 remained constant since 1982.
The long-term effects of this greening are hard to predict, but scientists speculate it could prevent soil erosion, increase plant life in deserts, and increase forest cover. On the other hand, it could increase fuel for forest fires, and provoke unexpected changes in habitats, requiring wildlife—or farmers—to adjust ways of living."
