Brazil nut journey under future climate change in Amazon.
Climate change is among the principal threats to global terrestrial biodiversity, especially to megadiverse ecosystems such as the Amazon rainforest. In this study, we investigate how it could affect an iconic forest speciesBertholletia excelsa(the Brazil nut) which has values in multiple dimensions...

Spatial distribution of atmospheric pollutants and fire outbreaks in the Pantanal biome from 2016 to 2021.
Pantanal fires have a significant impact on the environment. Anthropogenic emissions of residual gases have changed the tropospheric composition in this region due to burning. This study aims to analyze the spatial patterns of atmospheric pollutants (including carbon monoxide (CO), nitrogen dioxide ...

Projected changes in the frequency of compound hot and dry events over Tropical Brazil in CORDEX-CORE simulations.
Under global warming, extreme events have been increasing in the last decade and are projected to increase in the future with every increment of global warming. The potential increase in compound drought and hot events may induce a complex web of impacts on societies, ecosystems, and economies, incl...

Sensitivity analysis of solar irradiance estimates over a tropical region by cloud index models.
The downward global horizontal irradiance (GHI) modulates various physical processes on Earth and is essential in climate, ecology, and renewable resources studies. In recent years, the use of geostationary satellites for estimating downward global solar irradiance (GHI) has gained increasing intere...

Simulated isotopic fingerprint of the Atlantic Multidecadal Oscillation over South America and its relation to the Little Ice Age.
Linkages have been established between the Atlantic Multidecadal Oscillation (AMO) and surface air temperature variations, low-level jet streams, and precipitation trends in both northeastern Brazil and southeastern South America. Previous studies have discerned distinct wet-season (MarchMay) precip...

Evaluation of easterly wave disturbances over the tropical South Atlantic in CMIP6 models.
This study assesses the performance of the latest phase of Coupled Model Intercomparison Project (CMIP6) models in simulating easterly wave disturbances (EWD) over the tropical South Atlantic (TSA) impacting northeast Brazil (NEB). Initially, we evaluate simulated precipitation from 17 historical CM...

Regional relationship between total alkalinity and salinity in the surface waters of the western South Atlantic margin.
We examined the surface total alkalinity (AT) and salinity (SSS) distributions and their relationship along the southwestern South Atlantic Ocean margin off the Brazilian coast. In situ hydrographic data from shelf and slope stations were measured during three oceanographic cruises in October 2014 (...

Potential effects of climate change on cacti distribution and conservation in North American drylands.
Climate change is expected to adversely impact dryland biodiversity by reducing habitat suitability, especially for cacti species. One way to mitigate such effects on cacti is to reinforce the integrity of areas of high importance for their conservation, also known as high-value conservation areas (...
