Delayed cloud response reshapes aerosol radiative effects on marine low clouds

By tracking marine low clouds along three-day trajectories, this study reveals that aerosol-induced cloud adjustments peak one day downstream of the initial perturbation rather than at the source, demonstrating that the time-dependent nature of this coupling is a critical factor often overlooked in fixed-location analyses and a key contributor to uncertainties in aerosol indirect effect estimates.

Built-up Density, Not Greenness, Controls Urban Cooling Efficiency

This study reveals that while vegetation provides cooling benefits in both planned Islamabad and organic Rawalpindi, the efficiency of this cooling and the magnitude of urban heat islands are primarily governed by built-up density and land-cover configuration rather than vegetation abundance alone.

Ice Supersaturation and Enhanced Overturning during Antarctic Moisture Intrusions: Observations from the T-SCAN Campaign

Analysis of high-resolution radiosonde data from the 2025 T-SCAN campaign reveals that Antarctic moisture intrusions create extensive ice-supersaturated layers where accounting for phase-dependent thermodynamics significantly increases the diagnosed vertical extent of atmospheric overturning compared to traditional dry-stability estimates.

From Urban Growth to Material Accumulation: Reconstructing Building Stock Dynamics in Gothenburg, from 1960 to 2015

This study reconstructs the long-term dynamics of Gothenburg's residential building stock and material flows from 1960 to 2015 by integrating historical GIS, street-network characteristics, and machine learning to quantify a net accumulation of approximately 9.75 Mt of materials, demonstrating how such a framework can analyze the spatial formation and turnover of urban material stocks.

Earthquake drainage and drought timing

By combining a transient storage-drainage model with extensive catchment data from New Zealand and Chile, this study demonstrates that while earthquakes can accelerate post-seismic drainage, they do not necessarily increase drought vulnerability unless the enhanced drainage exceeds the logarithmic gain in accessible storage, a condition that remains difficult to confirm with current observational data.

Mobility of lead (Pb) isotopes during weathering of black shales in central Hunan (China): Implications on Pb isotopes used as an environmental tracer

This study demonstrates that lead isotopes in weathered black shales from central Hunan are derived from a two-endmember mixture of unradiogenic pyrite and radiogenic accessory minerals, confirming their utility as effective tracers for distinguishing natural from anthropogenic lead contamination in weathering catchments.

An ancient, deep, and ultra-depleted mantle domain beneath the northern Atlantic Ocean

This study identifies an ancient, ultra-depleted mantle domain beneath the northern Atlantic Ocean, characterized by high-degree melt extraction at great depths, which the authors propose represents preserved residues of ancient mantle plumes that contribute to the Earth's large-scale compositional structure.
