Arid Areas Greening Because of Higher CO2 Levels

Higher levels of carbon-dioxide has caused some of the Earth’s most arid regions to become more green, according to new research.

Scientists focused on the American southwest, Australia’s outback, the Middle East and parts of Africa, and found that from 1982 to 2010 there was a “fertilization effect” caused by increased carbon-dioxide levels.

Researchers predicted foliage would increase by 5 to 10 percent given the 14 percent increase in atmospheric CO2 concentration during the study …
