Study: increased carbon dioxide is greening deserts globally

CO2 is greening the planet?!? You mean that evil gas that Obama and the EPA are trying to declare a “pollutant”? And the same colourless, odourless, trace gas that kids at school are being taught to refer to as “carbon pollution”?
Carbon dioxide, greening the planet?! Shock horror.

Watts Up With That?

Enhanced levels of carbon dioxide are likely cause of global dryland greening, study says

From the “inconvenient truth” department and INDIANA UNIVERSITY:

Enhanced levels of atmospheric carbon dioxide are a likely key driver of global dryland greening, according to a paper published today in the journal Scientific Reports.

The positive trend in vegetation greenness has been observed through satellite images, but the reasons for it had been unclear.

After analyzing 45 studies from eight countries, Lixin Wang, assistant professor of earth sciences in the School of Science at Indiana University-Purdue University Indianapolis, and a Ph.D. student in Wang’s group, Xuefei Lu, concluded the greening likely stems from the impact of rising levels of atmospheric carbon dioxide on plant water savings and consequent increases in available soil water.

“We know from satellite observations that vegetation is greener than it was in the past,” Wang said. “We now understand why that’s…
