Beta effect of eCO2 can cause as much rainfall decrease as large-scale deforestation in the Amazon.
Amazon regions climate is particularly sensitive to surface processes and properties such as heat fluxes and vegetation coverage. Rainfall is a key expression of such land surface-atmosphere interactions in the region due to its strong dependence on forest transpiration. While a large number of past...- por Portal Padrão

Climate change-related risks and adaptation measures in South and Central America during the 21st century.
The consequences of climate change in South and Central America are already widespread and take on many forms. Albeit there is an increasing number of studies focusing on specific climate change-related risks in the region, a synthesis of risks for the 21st century, together with current and future ...- por Portal Padrão

Climate-induced hysteresis of the tropical forest in the fire-enabled Earth system model CM2Mc-LPJmL.
Tropical rainforests are recognized as one of the terrestrial tipping elements which could have profound impacts on the global climate, once their vegetation has transitioned into savanna or grassland states. While several studies investigated the savannization of, e.g., the Amazon rainforest, few s...- por Portal Padrão

South American fires and their impacts on ecosystems increase with continued emissions.
Unprecedented fire events in recent years are leading to a demand for improved understanding of how climate change is already affecting fires, and how this could change in the future. Increased fire activity in South America is one of the most concerning of all the recent events, given the potential...- por Portal Padrão

A model for urban biogenic CO2 fluxes: Solar-Induced Fluorescence for Modeling Urban biogenic Fluxes.
When estimating fossil fuel carbon dioxide (FFCO2) emissions from observed CO2 concentrations, the accuracy can be hampered by biogenic carbon exchanges during the growing season, even for urban areas where strong fossil fuel emissions are found. While biogenic carbon fluxes have been studied extens...- por Portal Padrão

Isotopic composition of precipitation in a southeastern region of Brazil during the action of the south Atlantic convergence zone.
The use of stable isotopes of hydrogen and oxygen is a tool widely used to trace water paths along the hydrological cycle, providing support for understanding climatic conditions in different spatial scales. One of the main synoptic scale events acting in southeastern Brazil is the South Atlantic Co...- por Portal Padrão

Reply to comment on “Comparison of cloud cover detection algorithms on sentinel-2 images of the Amazon tropical forest”.
In their comments about our paper, the authors remark on two issues regarding our results relating to the MACCS-ATCOR Joint Algorithm (MAJA). The first relates to the sub-optimal performance of this algorithm under the conditions of our tests, while the second corresponds to an error in our interpre...- por Portal Padrão

Advancing a toolkit of diverse futures approaches for global environmental assessments.
Global Environmental Assessments (GEAs) are in a unique position to influence environmental decision-making in the context of sustainability challenges. To do this effectively, however, new methods are needed to respond to the needs of decision-makers for a more integrated, contextualized and goal-s...- por Portal Padrão

Nutrient Balance and Use Efficiency in Agricultural Lands in the Vermelho River Watershed, Upper Pantanal, Brazil.
Agricultural systems play a key role in achieving many of the Sustainable Development Goals, established by the United Nations, given the current challenge of producing enough food to feed a global population that is expected to reach 10 billion people by 2050. More efficient and sustainable use of...- por Portal Padrão

The climate change potential effects on the run-of-river plant and the environmental and economic dimensions of sustainability.
In this work, we evaluate the environmental and economic sustainability dimensions of a run-of-river hydroelectric plant operation regarding environmental impacts and potential direct and indirect effects of climate change. Results suggest the generation of a vicious cycle of clean generation and di...- por Portal Padrão

Combining regional to local restoration goals in the Brazilian Atlantic forest
To achieve regional and international large-scale restoration goals with minimum costs, several restoration commitments rely on natural regeneration, a passive and inexpensive strategy. However, natural regeneration potential may vary within the landscape, mainly due to its historical context. In th...- por Portal Padrão
