Dynamics and Structure of the Natural Regenerative Layer in a Floodplain Forest in the District of Arapixuna, Santarém, Pará

This study documents the floristic composition and structural dynamics of a floodplain forest in Arapixuna, Pará, revealing a 72% mortality rate in the natural woody regenerative stratum over three years while highlighting the ecological resilience of key species like *Schizolobium amazonicum* to water stress.

Dynamic mapping of flood susceptibility and exposure associated with the El Niño phenomenon using machine learning and geospatial modeling in Trujillo, Peru

This study developed a dynamic geospatial framework using Random Forest machine learning and Sentinel-1 imagery to map flood susceptibility and exposure in Trujillo, Peru, demonstrating that the model effectively identifies priority areas under varying El Niño precipitation conditions without requiring retraining.

Climate responses to Antarctic meltwater depend on the timing of meltwater release

Using historically-calibrated ice sheet projections, this study reveals that Antarctic meltwater induces only weak global climate responses when released in a warming future climate, contrasting sharply with the strong impacts seen in earlier studies that assumed unrealistic pre-industrial or high-end release rates, thereby highlighting that the climatic effects of meltwater are highly sensitive to the timing of its release relative to Southern Ocean precipitation changes.

Advancing Microplastic Analysis in Complex Matrices Towards Harmonization: Insights from an Interlaboratory Study Supporting the Development of a Standardized Extraction Protocol

This interlaboratory study demonstrates that a harmonized extraction protocol for microplastics in compost is feasible and effective across diverse analytical techniques, while identifying that variability in quantification stems primarily from subsampling and analysis methods rather than the extraction process itself, thereby providing critical insights for the development of ISO standard 24899.

Accelerated Early 21st-century Warming from Declining Aerosol Emissions and its Implications for Near-term Climate Change

The paper reveals that the rapid post-2005 decline in global aerosol emissions, particularly sulphur, has significantly accelerated near-term warming by approximately 0.14°C, potentially causing the world to reach 1.5°C and 2°C thresholds years earlier and necessitating steeper greenhouse gas reductions to meet climate goals.

Zero-Deforestation Land Use Scenarios in the Brazilian Cerrado: Pasture Intensification for Agriculture, Livestock and Regeneration

This study demonstrates that intensifying pasture management across 13 million hectares of the Brazilian Cerrado could meet projected 2030 demands for soybean and livestock production without deforestation, simultaneously freeing land for native vegetation regeneration and increasing regional carbon stocks by up to 0.47 Pg by 2050.
