This study reveals that the uncontrolled leachate from the Reppe dumpsite in Addis Ababa causes extreme heavy metal contamination in surface water, particularly from cadmium, mercury, and lead, posing a severe ecological risk that far exceeds international safety limits and demands urgent remediation.
This study uses Earth system model simulations to demonstrate that a collapsed West Antarctic Ice Sheet combined with North Atlantic meltwater release during the Last Interglacial explains anomalous climate records and suggests the Antarctic ice sheet could contribute up to ~4 meters to global sea level.
Challenging the conventional view that oceanic upwelling drives the Walker Circulation, this study demonstrates that American landmass and orography are the fundamental drivers that anchor the circulation's subsiding branch and cool the eastern Pacific, amplified by atmospheric feedbacks.
This study presents a deep learning framework that successfully emulates high-resolution South Asian atmospheric variations, including meteorological fields and ozone, by training four different architectures on WRF-Chem data, with the UNet-3blk model achieving optimal performance despite challenges in reproducing PM2.5 variability.
This study employs an integrated approach combining Landsat remote sensing techniques (including PCA, band ratios, and MNF) with field investigations to successfully map lithological units, structural features, and alteration zones associated with alluvial gold deposits within the Kapoeta area of South Sudan's Arabian Nubian Shield.
This paper establishes a projection–lifting framework that converts non-Markovian Volterra memory in climate dynamics into a positive Markovian embedding, demonstrating its application to AMOC tail-risk geometry where a three-mode approximation of CMIP6 data reveals increasing residence in weak-overturning regimes and validates memory as a dynamical state variable for organizing trajectory-level risk rather than a simple forecast tool.
This study utilizes an exponential distribution model on historical and instrumental seismic data to demonstrate that major earthquakes (Mw > 6.7) in northeastern Crete follow a memoryless Poisson process, revealing an 85% probability of a subsequent event occurring within 90 years of the last 1935 mainshock.
Utilizing extensive microdata from Aceh and West Nusa Tenggara, this study demonstrates that rising relative humidity significantly exacerbates household food insecurity, particularly among rural and male-headed households, while highlighting that increased expenditure, education, and infrastructure access serve as critical mitigating factors.
This study evaluates the water quality of Nigeria's Otamiri River using an integrated UAV–GIS–laboratory framework to identify pollution hotspots, develop a high-accuracy predictive model for organic pollutant attenuation, and recommend targeted management interventions for a river currently unsuitable for direct drinking without treatment.
This study investigates socio-technical drivers of greenhouse gas emissions from on-site sanitation systems in tropical urban communities, revealing that household income and population size significantly influence CO₂ and CH₄ emissions from septic tanks, thereby highlighting the need for targeted, behavior-informed mitigation strategies.
