Land-use impacts of Brazilian wind power expansion.
While wind power is a low-carbon renewable energy technology with relatively little land footprint, the necessary infrastructure expansion still has land-related environmental impacts. Brazil has seen more than a ten-fold increase in wind power capacity in the last decade. However, little is known a...

How well does the HadGEM2-ES coupled model represent the Southern Hemisphere storm tracks?.
This study presents an assessment of the ability of the Hadley Centre Global Environment Model version 2-Earth system configuration (HadGEM2-ES)-in simulating the mid-latitude storm tracks over the Southern Hemisphere (SH). The storm tracks are primarily assessed using cyclone tracking using data fr...

How norms, needs, and power in science obstruct transformations towards sustainability.
After decades of inadequate responses to scientists' warnings about global environmental threats, leading analysts of the science-policy interface are seeking an important shift of research focus. This switch is from continued modeling and diagnoses of biogeochemical conditions in favor of enhanced ...

Functional rather than taxonomic diversity reveals changes in the phytoplankton community of a large dammed river.
River damming reduces the dispersal rates of biota and filter species by altering the local environmental conditions. Although phytoplankton is a key biotic group to indicate changes in aquatic environments, the effects of river damming on the longitudinal distribution of phytoplankton communities a...

Environmental drivers of water use for caatinga woody plant species: combining remote sensing phenology and sap flow measurements.
We investigated the water use of Caatinga vegetation, the largest seasonally dry forest in South America. We identified and analysed the environmental phenological drivers in woody species and their relationship with transpiration. To monitor the phenological evolution, we used remote sensing indice...

Extreme rainfall events over Rio de Janeiro State, Brazil: Characterization using probability distribution functions and clustering analysis.
Extreme rainfall events are likely to become more frequent according to recent scenarios of climate change. This issue is especially important over regions with complex topography, which enhances rainfall variability when associated with weather patterns. The state of Rio de Janeiro (SRJ), southeast...
