Impacts on South America moisture transport under Amazon deforestation and 2 °C global warming.

The increase in greenhouse gasses (GHG) anthropogenic emissions and deforestation over the last decades have led to many chemical and physical changes in the climate system, affecting the atmosphere's energy and water balance. A process that could be affected is the Amazonian moisture transport in t...

RECCAP2 Future Component: Consistency and Potential for Regional Assessment to Constrain Global Projections.

Projections of future carbon sinks and stocks are important because they show how the world's ecosystems will respond to elevated CO2 and changes in climate. Moreover, they are crucial to inform policy decisions around emissions reductions to stay within the global warming levels identified by the P...

Sink or carbon source? how the Opuntia cactus agroecosystem interacts in the use of carbon, nutrients and radiation in the Brazilian semi-arid region.

Anthropogenic disturbances directly influence environmental processes and increase the concentration of carbon (C) in the atmosphere. Here, we compare the differences in the seasonality of the balance of carbon, energy, and radiation, as well as seek to identify the interrelationships between these ...

Changes in atmospheric circulation and evapotranspiration are reducing rainfall in the Brazilian Cerrado.

Here we analyze the trends of rainfall and the frequency of rainy days over the Brazilian Cerrado between 1960 and 2021 in four distinct periods according to the seasonal patterns over the region. We also evaluated trends in evapotranspiration, atmospheric pressure, winds, and atmospheric humidity o...

Fire in highland grasslands in the Atlantic Forest Biome, a burned areas time series analysis and its correlation with the legislation.

Fire has been an intrinsic ecological component of the ecosystems, affecting the public, economic, and socio-cultural policies of human-nature interactions. Using fire over grassland vegetation is a traditional practice for livestock in the highland grasslands and has economic and environmental cons...

Do the type of impact and vulnerability dimension matter when assessing natural hazard vulnerability?

Communities across the United States are continually impacted by natural hazards, leading to material and human losses. Natural Hazard Vulnerability (NHV) assessments can help identify variables that can increase the community's susceptibility to these losses. Several studies have assessed NHV, but ...

Increased Amazon carbon emissions mainly from decline in law enforcement.

The Amazon forest carbon sink is declining, mainly as a result of land-use and climate change14. Here we investigate how changes in law enforcement of environmental protection policies may have affected the Amazonian carbon balance between 2010 and 2018 compared with 2019 and 2020, based on atmosphe...

Multi-experiment assessment of soil nitrous oxide emissions in sugarcane.

Soil nitrous oxide (N2O) fluxes comprise a significant part of the greenhouse gas emissions of agricultural products but are spatially and temporally variable, due to complex interactions between climate, soil and management variables. This study aimed to identify the main factors that affect N2O em...
