Large-scale changes in precipitation and temperature in South America under climate change – ensemble climate model projections and uncertainties.
Despite current state-of-the art global climate model (GCMs) ability to simulate well the large scale state of the global climate, there is significant variation in future climate projections of precipitation and temperature changes in South America. In order to adequately assess the possible impact...

Local and remote modes of variability of the Atlantic cold Tongue mode.
The dominant modes of coupled ocean-atmosphere variability of the Tropical Atlantic are investigated using observational data, focusing on the cold tongue mode. The seasonal evolution and interannual variability of each mode is obtained from a joint EOF analysis of the three elements of the Bjerknes...

Climate control of terrestrial carbon exchange across biomes and continents.
Understanding the relationships between climate and carbon exchange by terrestrial ecosystems is critical to predict future levels of atmospheric carbon dioxide because of the potential accelerating effects of positive climate-carbon cycle feedbacks. However, directly observed relationships between ...

Mudanças na circulação atmosférica sobre a América do Sul para cenários futuros de clima projetados pelos modelos globais do IPCC AR4.
Neste trabalho são analisadas as mudanças no padrão de circulação que possam vir a acontecer no clima da América do Sul (AS), como conseqüência do aumento nas concentrações dos gases de efeito estufa. Para isto utilizam-se cinco modelos globais do IPCC AR4 (CCCMA, GFDL, HadCM3, MIROC e GIS...

Deforestation and conservation in major watersheds of the Brazilian Amazon.
Conserving natural vegetation cover is of critical importance for maintaining the ecological integrity and hydrological properties of large river basins (more than 100 000km2). Recent estimates indicate that more than 700 000km2 of Brazilian Amazon have already been deforested, and to reduce further...

Variability of carbon dioxide flux from tropical (Cerrado) hydroelectric reservoirs.
Hydroelectric reservoirs generate energy without significant combustion of fossil fuels. However, these systems can, potentially, emit greenhouse gases (GHGs) at a rate which may be significant at the global scale, and, possible, co-equal, per kilowatt-hour, to that from conventional coal or oil-fir...
