Global Warming and Climate Change} Desert formation is how the planet's low carbon dioxide is keep above 180 part per million

How does this work? If there were only C4 and CAM plants on the planet, then it would not work as well. But C3 plants need to open up their stoma's larger when carbon dioxide levels are lower, and if the area where the C3 plants live, also happens to produce less rainfall than other places, this extra stress may cause the loss of the plant life living in that area. As we know, without a full-plant life in any one place, this can cause a cascading effect, because of the loss of plant respiration, injecting that water back into the atmosphere, then there are fewer clouds and therefore less rain. This can just turn into a short-duration event, or it can snowball into a semi-arid or arid area. The good news here is without that plant life using carbon dioxide from the atmosphere. is become available elsewhere. As time goes on the carbon that had been stored in the soil then becomes carbon dioxide by decomposition, and with no replacement from living plant life, that carbon becomes available for the rest of the planet. There can be many times more carbon stored in the soils, than in living plant life, on the surface! The reason that I used a certain number, for when desert formation becomes a larger factor in keeping that level of carbon dioxide in the atmosphere more consistent, is not that it is an absolute but because at that level is when the stoma of many C3 plants See's the most increase in their size of openings, leading to extreme loss of water on a windy and warm day. You will also note that around those levels in the atmosphere, the planet may start to enter into another glaciers phase! It is important to note, that with an even higher level of carbon dioxide in the atmosphere, desert formations can occur, Several factors can come into play here, one would be overgrazing by livestock, trying to increase herd count that simply may not be able to support those number when rainfall is less than expected, or perhaps changing to a type of animal that grazes closer to the ground then some kind of plants can tolerate. Drought conditions can occur, for many reasons, or fires may instill a temporary loss of plant life, in combination with loss of plant cover and many times the loss of the roots that comes with it. may cause blowouts to occur! Simply put, desert growth has a real effect on increasing co2 in the atmosphere. Reach me at 402-890-7946 in the USA  or at   danielkadavy212gmail.com Thank you for reading Dan!
