Some think that the Amazon could flip to desert, with enough deforestation.

If it was destroyed by humans, maybe it can be restored by humans.<p>If a change in planetary albedo can disrupt weather patterns, then gross control should likely afford for a reversal. If you could change the reflective surface of country-sized zones, would the opposite be possible?<p>What if the general reflective surface of uninhabited areas were darkened across the spectrum, but especially in the radiative thermal and infrared region? Would monsoons return?<p>10,000 years is pre-historic. I wonder how many seasons were required to transform the region, given that the desert continues to expand even today.<p>If monsoons were returned, figure 2 generations of monsoons (40 years) might show significant reversal?
