In an effort to fight climate change, the Sahara Desert could be going green… literally.
Plans are being made to terraform the entire Sahara desert; changing it from a dry, barren landscape to a lush green space. If successful, the transformation could remove 7.6 billion tons of atmospheric carbon yearly. How could we change the nature of such a vast, isolated landscape?

The globe is already greening due to the higher CO2 levels. It does not require manmade intervention. It is happening naturally.
As for CO2 being the cause of climate change, I refer you to http://www.biocab.org/carbon_dioxide_geological_timescale.html which clearly shows that over the entire geological history of our planet, CO2 increases FOLLOW temperature rises. Thus they CANNOT be a causative factor.
