Reducing uncertainties of climate projections on solar energy resources in Brazil.
The share of solar power in Brazils electrical grid has rapidly increased, relieving GHG emissions and diversifying energy sources for greater energy security. Besides that, solar resource is susceptible to climate change, adding uncertainty to electrical grid resilience. This study uses satellite a...

Spatio-temporal tendencies of urban land surface temperature on the Andean piedmont under climate change: A case study of Metropolitan Lima, Peru (1986–2024).
The increase in land surface temperature (LST) in megacities has contributed to global warming due to poor urban planning and high population concentration. This study analyzes spatio-temporal trend patterns of LST in the city of Metropolitan Lima, Peru, during the summers of 19862024. The Mann-Kend...

Isoprene nitrates drive new particle formation in Amazon’s upper troposphere.
New particle formation (NPF) in the tropical upper troposphere is a globally important source of atmospheric aerosols1, 2, 3-4. It is known to occur over the Amazon basin, but the nucleation mechanism and chemical precursors have yet to be identified2. Here we present comprehensive in situ aircraft ...

South Atlantic convergence zone and ENSO occurrence in the 2000–2021 period.
In this study we defined the association of SACZ episodes with ENOS phases during the 2000–2021 summer seasons, considering November to March months, and the circulation associated patterns. Each SACZ episode was classified when OLR values were below 220 W m− 2 and precipitable water values abov...

Fire weakens land carbon sinks before 1.5 °C.
To avoid the worst impacts of climate change, the Paris Agreement committed countries to pursue efforts to limit global warming to 1.5 °C by urgently reducing greenhouse gas emissions. However, the Paris temperature ambitions and remaining carbon budgets mostly use models that lack feedback among...

Entre promessas e defasagens, fronteiras e abismos: aberturas para uma filosofia especulativa do sistema terrestre.
Desde meados dos anos 1980, a Earth System Science vem se desenvolvendo e consolidando com o abrangente campo capaz de produzir conhecimento para o enfrentamento das crises vinculadas ao que se convencionou chamar de antropoceno. Mesmo considerado de fronteira, e que de fato tenha conseguido materia...
