Schematic of potential feedback processes involved in Amazonian climate change and forest degradation, involving either or both global warming or direct human impacts on the forest. Feedbacks involving specific SST changes, atmospheric circulation and Amazon precipitation rely on particular responses of regional climate change in the Hadley Centre climate models—these are seen in some other models, but not all. A large number of studies suggest impacts on regional climate through reduced evapotranspiration following deforestation. T_*, surface temperature.
