Climate change, deforestation, and the fate of the Amazon.

چکیده
The forest biome of Amazonia is one of Earth's greatest biological treasures and a major component of the Earth system. This century, it faces the dual threats of deforestation and stress from climate change. Here, we summarize some of the latest findings and thinking on these threats, explore the consequences for the forest ecosystem and its human residents, and outline options for the future of Amazonia. We also discuss the implications of new proposals to finance preservation of Amazonian forests.

Amazon deforestation and climate change.
A coupled numerical model of the global atmosphere and biosphere has been used to assess the effects of Amazon deforestation on the regional and global climate. When the tropical forests in the model were replaced by degraded grass (pasture), there was a significant increase in surface temperature and a decrease in evapotranspiration and precipitation over Amazonia. In the simulation, the lengt...
متن کاملRegional feedbacks among fire, climate, and tropical deforestation
[1] Numerous studies with general circulation models suggest that tropical deforestation can result in regional-scale climate change; namely, increased air temperature and wind speed and reduced precipitation and relative humidity. To quantify how this climate change should affect fire risk, we used the National Center for Atmospheric Research (NCAR) CCM3.2 general circulation model and remote ...
متن کاملDeforestation in Amazonia impacts riverine carbon dynamics
Fluxes of organic and inorganic carbon within the Amazon basin are considerably controlled by annual flooding, which triggers the export of terrigenous organic material to the river and ultimately to the Atlantic Ocean. The amount of carbon imported to the river and the further conversion, transport and export of it depend on temperature, atmospheric CO2, terrestrial productivity and carbon sto...
متن کاملThe future of the Amazon: new perspectives from climate, ecosystem and social sciences
The potential loss or large-scale degradation of the tropical rainforests has become one of the iconic images of the impacts of twenty-first century environmental change and may be one of our century's most profound legacies. In the Amazon region, the direct threat of deforestation and degradation is now strongly intertwined with an indirect challenge we are just beginning to understand: the po...
متن کاملThe impact of Amazonian deforestation on Amazon basin rainfall
We completed a meta-analysis of regional and global climate model simulations (n=96) of the impact of Amazonian deforestation on Amazon basin rainfall. Across all simulations, mean (±1σ) change in annual mean Amazon basin rainfall was 12 ± 11%. Variability in simulated rainfall was not explained by differences in model resolution or surface parameters. Across all simulations we find a negative ...
