The Saharan stakes in the desert are thus regional, but beyond they join a wider logic of global rehabilitation.
Fossil fuels, carbon, coal and gases are not the only factors which contribute to climate change. Sharan desert precipitations are low (1 in 100mm) but violents, fed by the thermal shock caused by cold air masses from the ocean blending with hot ones from the desert. Nevertheless evaporation is almost immediate, because water and carbon are bounded to organic material from the saharan grounds.
