There is one thing that worries climate scientists universally: the positive feedback loop. This is a process where changing one quantity changes the second one, and the change in the second quantity, in turn, changes the first. Scientists fear a positive feedback loop may spiral the climate crisis out of control.
Desertification is an example of a positive feedback loop, just as the melting of the Arctic ice cap, thawing of the Siberian permafrost, and the large-scale release of methane from methane hydrate lying on the sea and ocean floors.
The climate crisis is causing desertification and, in turn, desertification is exacerbating the crisis. The cycle continues.
Let me explain this, but first a disclaimer: this is an oversimplified version of an extremely complex process.
