Decoupling must accelerate threefold to align national environmental footprints with planetary boundaries

Despite efficiency gains in advanced economies, no nation currently operates within all seven planetary boundaries due to offsetting trade-sourcing effects and rising impacts in emerging economies, necessitating a threefold acceleration in decoupling rates for critical domains like climate and biosphere integrity to achieve global sustainability by 2050.

Validation Of a Modified Normalized Kruskal-Walis Fractal Dimension For Characterizing Pore Structure in Khuff Carbonate Reservoirs, Central Saudi Arabia

This study validates a modified normalized Kruskal-Wallis fractal dimension approach as a robust and highly consistent method for characterizing pore-structure heterogeneity in Khuff carbonate reservoirs, demonstrating a strong positive correlation between fractal dimension and permeability while confirming its applicability across diverse porous materials.

Increasing bird diversity in a landscape in transition

A resurvey of the Côa River basin reveals that rural depopulation and subsequent farmland extensification have driven a 28% increase in bird diversity, primarily benefiting forest-associated and generalist species while leaving farmland specialists stagnant, highlighting complex ecological shifts even within seemingly stable landscapes.

Vertical structure of phytoplankton in stratified oceans will shift in a warming climate

Using CMIP6 projections and a two-layer ecosystem model, this study reveals that high CO2 emissions will significantly alter the vertical distribution of phytoplankton in stratified oceans by increasing subsurface biomass while decreasing surface biomass, whereas sustainable emission pathways maintain stability, highlighting the critical need to reduce emissions to prevent unknown consequences for marine ecosystems and biogeochemical cycles.

UHI Mitigation with Green Infra: Cairo new Capital Central Business District as a Case Study

This study demonstrates that implementing strategic green infrastructure, particularly clustered vegetation, in Cairo's New Administrative Capital Central Business District significantly mitigates the urban heat island effect, reduces cooling energy demand by up to 12.7% under future climate scenarios, and offers long-term economic viability for climate-resilient urban planning in arid regions.

A Fractional Eulerian Dispersion Model Based on Hausdorff Derivatives for Pollutant Transport in the Planetary Boundary Layer

This paper presents and validates a novel fractional Eulerian dispersion model based on Hausdorff derivatives, which effectively simulates anomalous pollutant transport in the planetary boundary layer by incorporating a fractal dimension parameter and demonstrates superior performance over classical approaches under complex turbulent conditions.

Causes of the Desiccation of Lake Victoria at 17 ka

This study uses a high-resolution triple-nested model to demonstrate that the desiccation of Lake Victoria 17,000 years ago was primarily driven by regional climate responses to reduced greenhouse gases, cooler temperatures, and altered insolation, which collectively disrupted moisture convergence and collapsed the lake's characteristic precipitation cycles rather than by remote forcing.
