A breakeven grid-emission threshold for waste-to-energy: reordering municipal solid waste pathways under Bahrain’s fossil-dependent grid

This paper establishes that for Bahrain's fossil-dependent grid, waste-to-energy incineration only becomes a net climate benefit when grid carbon intensity exceeds 0.96 kg CO₂-eq/kWh, demonstrating that material-recovery pathways consistently outperform incineration and should form the core of an integrated municipal solid waste strategy.

Evidence the ocean is losing less heat in the northern Atlantic and the AMOC has started to slowly weaken

This study provides robust evidence that the Atlantic Meridional Overturning Circulation (AMOC) has weakened by approximately 14% over the last 30 years, a change driven by a significant reduction in ocean heat loss in the northern Atlantic that is attributed to forced climate change.

Long-Term Physiologically Equivalent Temperature Trends and Climate-Related Occupational Heat Exposure Across Industrial Sectors in Iran

This study integrates a 66-year Physiologically Equivalent Temperature (PET) climatology with the spatial distribution of major industrial sectors across Iran to reveal that most industrial facilities, particularly in mining, metal processing, and petroleum industries, are concentrated in regions experiencing strong to extreme heat stress, thereby establishing a scalable framework for assessing national occupational thermal vulnerability.

Satellite-Based Forecasting of NO₂ and SO₂ Concentrations in Sri Lanka using SARIMA Time-Series Models

This study demonstrates the potential of using Sentinel-5P TROPOMI satellite data combined with SARIMA time-series models to forecast monthly NO₂ and SO₂ concentrations in five Sri Lankan districts, achieving high accuracy for NO₂ while highlighting the significant challenges in predicting irregular SO₂ levels and converting column density to ground-level concentrations.

Multi-Tiered Magmatic Plumbing System of the Tatun Volcano Group, Taiwan: Insights from Mineral Thermobarometry and Reservoir Evolution

This study utilizes mineral thermobarometry on deep borehole samples from Taiwan's Tatun Volcano Group to reconstruct a multi-tiered magmatic plumbing system, revealing a deepening and shrinking magma reservoir since the Pleistocene that, while currently stable, retains the potential for future low-explosivity effusive eruptions primed by a shallow hydrothermal system.

Seasonal Switching of Drinking-Water Sources from the Rainy to the Dry Season among Households in Somalia: Evidence from the 2022 Somalia Integrated Household Budget Survey

Using data from the 2022 Somalia Integrated Household Budget Survey, this study reveals that 17.25% of households switch their main drinking-water source between seasons, with significantly higher prevalence among nomadic and rural populations compared to urban residents, highlighting the need for water planning to account for these seasonal and geographic variations.

Contrasting frequency-dependent seismic velocity responses in Northern Nagano and Mount Fuji regions after the 2011 Mw 9.0 Tohoku-Oki earthquake

This study utilizes ambient noise seismic interferometry to reveal that the 2011 Tohoku-Oki earthquake induced distinct, frequency-dependent seismic velocity decreases in the Northern Nagano and Mount Fuji regions, where volcanic areas showed broad susceptibility to dynamic stress while a localized anomaly near the Northern Nagano earthquake exhibited stronger frequency dependence, suggesting a contribution from subsequent triggered seismicity.
