Scientists have known for many years that increased levels of carbon dioxide (CO2) have helped boost green foliage across the world’s arid regions.
Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO), for instance, published a study in 2013 that found that CO2 fertilization correlated with an 11 percent increase in foliage cover from 1982-2010 across parts of the arid areas studied in Australia, North America, the Middle East, and Africa.
