Avaliação experimental de diferentes bases de dados de concentração de aerossóis na região central Amazônica
Aerossóis podem ser definidos como quaisquer partículas sólidas ou liquidas que ficam em suspensão na atmosfera, sendo proveniente de diferentes fontes, naturais e antrópicas, influenciando significativamente no balanço de radiação do planeta. Na Amazônia, esse material particulado é emiti...

Degradação da terra nos biomas Cerrado e Caatinga no contexto dos ODS.
A degradação da terra é largamente conhecida pelos impactos negativos ao meio ambiente, e se refere à perda da produtividade e complexidade biológica e econômica da terra, e quando presente em regiões subúmidas e secas, como na Caatinga, é denominada Desertificação. A ONU estabeleceu a me...

Extreme precipitation events over the east coast of northeast Brazil: Synoptic study and MPAS simulation
In the present study two extreme events that occurred in the East Coast of Northeast Brazil (ENEB) during 2022 and 2023 were evaluated. These events are becoming increasingly frequent in all regions of Brazil, associated with significant material and human losses, emphasizing the significance of a d...

A large net carbon loss attributed to anthropogenic and natural disturbances in the Amazon Arc of Deforestation.
The Amazon forest contains globally important carbon stocks, but in recent years, atmospheric measurements suggest that it has been releasing more carbon than it has absorbed because of deforestation and forest degradation. Accurately attributing the sources of carbon loss to forest degradation and ...

Prioritizing Amazon Forest conservation: Assessing potential biomass under climate change.
This study aims to identify the capacity of intact forests to maintain Above Ground Biomass (AGB) under new climate conditions. Using a predictive approach under different climate scenarios (SSP12.6 and SSP58.5), and considering the mean of General Circulation Models (GCMs) for the period (20212040)...

Socio-geoenvironmental vulnerability index (SGeoVI) derived from hybrid modeling related to populations at-risk to landslides.
In the present study, we propose a transdisciplinary investigation aimed at developing an index to assess the vulnerability to landslides in the Brazilian municipality of São José dos Campos. The proposed Socio-Geoenvironmental Vulnerability Index (SGeoVI) was developed using a hybrid modeling app...

CO2 emissions in the Amazon: are bottom-up estimates from land use and cover datasets consistent with top-down estimates based on atmospheric measurements?
Amazon forests are the largest forests in the tropics and play a fundamental role for regional and global ecosystem service provision. However, they are under threat primarily from deforestation. Amazonia's carbon balance trend reflects the condition of its forests. There are different approaches to...

Investigation of landslide hazard areas in the municipality of Cunha (Brazil) and climate projections from 2024 to 2040.
Climate change can modify the frequency and intensity of extreme rainfall across the globe, leading to changes in hazards posed by rainfall-induced landslides. In Brazil, an example of a location with a high occurrence of landslides and with few studies on the subject is the municipality of Cunha, l...

Nature-based solutions are critical for putting Brazil on track towards net-zero emissions by 2050.
Most of the world's nations (around 130) have committed to reaching net-zero carbon dioxide or greenhouse gas (GHG) emissions by 2050, yet robust policies rarely underpin these ambitions. To investigate whether existing and expected national policies will allow Brazil to meet its net-zero GHG emissi...

Assessment of soil loss susceptibility in geodetic landmarks for the past and future climate change scenarios.
Geodetic landmarks (GLs) are essential for obtaining precise height, horizontal coordinates, and the Earth's gravity field. This study aims to assess the soil susceptibility of GLs for past, present, and future scenarios, considering the projected anthropogenic effect from Coupled Model Intercompari...

Asphyxiation of Metarhizium robertsii during mycelial growth produces conidia with increased stress tolerance via increased expression of stress-related genes.
Little is known about the impact of hypoxia and anoxia during mycelial growth on tolerance to different stress conditions of developing fungal conidia. Conidia of the insect-pathogenic fungus Metarhizium robertsii were produced on potato dextrose agar (PDA) medium under normoxia (control = normal ox...
