Fracture development mechanism of borehole walls in deep drilling

This study integrates numerical simulations, theoretical analysis, and laboratory experiments to reveal that thermal damage, horizontal in-situ stress, and drilling fluid pressure collectively govern the evolution and morphology of borehole wall fractures in deep granite drilling, providing a theoretical basis for enhancing wellbore stability and optimizing drilling fluid technologies.

Human behavioral responses to climate change reshape climate projections

By integrating human behavioral responses into climate models, this study reveals that factors like action confidence and climate anxiety can dynamically reshape future warming trajectories by up to ±1°C, demonstrating that human behavior is an active component of the climate system capable of either amplifying or mitigating climate change depending on the specific emissions pathway.

Enhancing European soil monitoring with citizen science data

This study demonstrates that integrating citizen science data with existing European monitoring programs, particularly for soil pH, can effectively enhance large-scale soil monitoring by improving digital soil mapping accuracy and expanding coverage to underrepresented environments like urban soils.

Spatiotemporal Heterogeneity of Daily Rainfall Persistence across the Maluku Archipelago: A First-Order Markov Chain Analysis of ERA5 Reanalysis Data (2000–2025)

This study utilizes a first-order Markov chain analysis of ERA5 reanalysis data (2000–2025) to characterize the pronounced spatiotemporal heterogeneity of daily rainfall persistence across the Maluku Archipelago, revealing how the interplay between monsoonal circulation and complex island topography governs dry–wet spell dynamics and extreme rainfall thresholds in this data-sparse tropical region.

Temporal and spatial scales of extremes of daily tropical rainfall : the example of Thailand (1979-2024)

This study analyzes 45 years of daily extreme rainfall in Thailand using 75 rain gauges and three gridded datasets to reveal that while MSWEP best reproduces event occurrence, all gridded products tend to underestimate extreme thresholds and overestimate spatial scales, and while ERA5 captures the observed long-term intensification of extreme rainfall frequency, MSWEP fails to do so.

Performance evaluation of retrofit planters as nature-based solutions for urban stormwater attenuation

This study empirically evaluates the hydrological performance of retrofit planters as nature-based solutions for urban stormwater management at both individual and network scales in the UK, demonstrating significant peak flow reduction and delay while highlighting design uncertainties related to roof catchment contributions.

Carbon abatement costs are negative for many electric vehicles across U.S. cities

This study demonstrates that while battery electric vehicles consistently offer the lowest life-cycle greenhouse gas emissions across 20 U.S. cities, small and midsize models often achieve negative carbon abatement costs by being both cheaper to own and cleaner than conventional alternatives, making electrification a cost-effective strategy for emissions reduction even for larger vehicles.

Improvements of CMIP6 over CMIP5 for Simulating Indian Summer Monsoon Rainfall and Indian Ocean Teleconnections

This study demonstrates that CMIP6 models exhibit significant improvements over CMIP5 in simulating Indian Summer Monsoon rainfall, its spatial structure, and associated Indian Ocean teleconnections, evidenced by higher correlation coefficients, better variance capture, and more realistic representation of large-scale circulation features.

A Statistical Investigation of Four-Point Relay Seismicity Patterns Across Four Regional Datasets

This study utilizes a statistical framework and iterative traceback algorithm on 20,693 earthquake records from 1960–2026 to demonstrate that four-point relay seismicity chains occur with a significantly non-random 41.30% completion probability within a 168-hour window, revealing distinct regional susceptibilities and energy attenuation patterns that offer new insights into stress transfer and intermediate-term seismic hazard assessment.
