Current models measure air currents and atmospheric gasses while ignoring how ground conditions,ie: amount of forage on the ground also act as a driving force for upper air currents. These models also leave out the calculations for how much greenhouse gasses would be reduced if desertification was reversed worldwide.
Part of the curiosity stems from the facts that Sahara Desert has fossils of mega flora, and evidence of massive irrigation systems. I was told by one researcher that the only way climate scientists have been able to recreate the moisture needed for the kinds of fossils found, was to add the plants, and the moisture came. Nazca Peru, the driest place in the world, has ruins of irrigation systems, along with root systems four feet below the barren ground. In addition to these two situations, weather researchers have observed historical rainfall patterns changing in locations where a single farmer changes from conventional methods to no till, cover crop methods.
This begs the question as to the accuracy of current climate models which ignore desertification. Wouldn't climate models be more accurate if climate models also took into account ground temperatures from global desertification and water cycle changes from urbanization of large areas? Is it possible that grasses and vegetation drive upper air currents as much as atmospheric gasses? Considering not a single domesday prediction from the "settled science" based on current models has come close to occuring, it would seem that the incomplete climate models would be inaccurate. This leaves the possibility that most of man made climate change could be alleviated by simply regenerating lands which have become desertified.
