Researchers including Vizy by contrast suggest that the Amazon will dry to a open grassland / scrubland ecosystem, called Caatinga

But the 'biotic pump' theory, rooted in conventional physics and recently confirmed by experiment, shows that the interior of a forest-free Amazon will be as dry as the Negev desert. We must save the Amazon before it enters a permanent and irreversible dessication.

Seems to me that widespread deforestation is aggravating stalled hot-weather trends by blocking this kind of circulation. The leaf area of a mature forest offers considerably more surface area for evaporation than the same area of open water on ocean or inland lake.
