Dendroclimatological Study of Pinus roxburghii Growth Variation along an Elevational Gradient in the Lesser Himalayas, Pakistan

This study utilizes tree-ring chronologies from *Pinus roxburghii* across an elevational gradient in the Lesser Himalayas of Pakistan to demonstrate that March precipitation and temperature are dominant growth drivers, while revealing that elevation modulates the seasonal breadth of climate sensitivity, with upper elevations showing the strongest response to hydroclimatic variability.

GIS-Integrated Analysis of Spatial and Vertical Variability in Airborne Pollen and Fungal Spore Concentrations Across an Urban Campus in Islamabad, Pakistan

This study utilized a custom low-cost sampler and GIS analysis to reveal significant spatial and vertical variability in airborne pollen and fungal spore concentrations across an urban campus in Islamabad, demonstrating that bioaerosol levels are strongly influenced by local land cover, wind patterns, and sampling height.

Asymmetric precursors modulate western North Pacific subtropical high predictability

This study reveals that the subseasonal predictability of the western North Pacific subtropical high is inherently sign-asymmetric, with positive and negative anomaly events arising from distinct precursor pathways and exhibiting contrasting forecast spreads and sources of predictability.

When a year starts shapes global hydrological conclusions

This study introduces the first observation-based global definition of the water year, demonstrating that aligning the annual start with local hydrological cycles—rather than using an arbitrary calendar date—significantly improves the accuracy of global water-balance analyses and estimates of interannual variability.

Distribution and ecological risk assessment of Heavy metal contamination in surface water from Leachate of the Reppe dumpsite, Addis Ababa, Ethiopia (Rainy Season)

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.

West Antarctic Ice Sheet collapse and North Atlantic meltwater reconcile Last Interglacial climate records

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.

The origin of the Walker Circulation

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.
