Reduced Distinctiveness of Extreme El Niño Teleconnections in Warmer Climates

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract In today's climate, extreme El Niño events (e.g., 1982–1983, 1997–1998) generate stronger and eastward‐shifted teleconnections relative to moderate El Niño and La Niña events, leading to distinct North American impacts such as enhanced rainfall over California and warming over northeastern North America.

Buoyancy Flux and Its Environmental Modulation in the Vertical Development of Shallow Cumulus in the Central Amazon

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract This study investigates the vertical development of shallow cumulus (ShCu) clouds in the Central Amazon (CAMZ) by combining large‐eddy simulations (LES) with observational data from the GoAmazon2014/5 campaign. Analyses of turbulent kinetic energy budgets, updraft mass flux, moisture flux, and surface fluxes across cloud sizes indicate that ...

Impacts of Deforestation‐Driven Rainfall Reductions on Amazonia Forest Stability

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The stability of Amazonian vegetation is strongly influenced by land–atmosphere feedbacks. It has been hypothesized that deforestation‐induced precipitation decline may lead to widespread forest decline across the entire basin. Using a moisture‐tracking model, we quantify how deforestation across South America alters downwind rainfall and ...

Effects of land management on soil carbon storage in the Brazilian Amazon

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract This study assessed the influence of land use on soil physical and chemical properties and evaluated machine learning (ML) models for predicting soil organic carbon (SOC) content and stocks in the top 0–30 cm layer across selected sites in the Brazilian Amazon. A total of 649 georeferenced samples of surface soil were analyzed for soil texture,

Compositional Characterization, Quality Parameters, and Physicochemical and Bioactive Properties of Pequi ( Caryocar brasiliense ) Oils From Xingu and Cerrado in Mato Grosso, Brazil

Journal of the American Oil Chemists' Society, Volume 103, Issue 6, Page 609-622, June 2026.
Cerrado oil is richer in MUFA and antioxidant compounds, while Xingu oil shows higher SFA and enhanced oxidative stability, reinforcing the potential of pequi oil as a sustainable bioactive ingredient. ABSTRACT Pequi ( Caryocar brasiliense ) is a native fruit widely distributed in Brazilian biomes, specially in Cerrado, known for its high oil yield and
