The Lithium Iron Phosphate Alchemy Problem: Circularity Deficit, Extended Producer Responsibility Absence, and Unrecovered Lithium Value in Rwanda's Commercial E-Mobility Fleet (2026 to 2030)

This study quantifies a projected annual 319.59-tonne circularity deficit and up to $1.23 million in unrecovered lithium value by 2030 within Rwanda's commercial e-mobility sector, attributing these losses to a lack of domestic recycling infrastructure and delayed Extended Producer Responsibility policies, while proposing a costed escrow mechanism to fund the necessary collection systems.

Quantifying the Contribution of Traditional Ecological Knowledge to Coral Reef Resilience under Climate Stress in Oceania

This study synthesizes systematic reviews and multi-source datasets to demonstrate that integrating Traditional Ecological Knowledge with contemporary science significantly enhances coral reef resilience in Oceania, resulting in 20% to 35% higher coral cover retention and faster recovery rates compared to non-managed systems despite climate-driven stressors.

Resolved boundary currents of Atlantic Water intensify the Beaufort Gyre in a warming Arctic Ocean

This study demonstrates that ultra-high-resolution modeling reveals intensified, resolved Atlantic Water boundary currents drive a contraction and strengthening of the Beaufort Gyre under warming, a mechanism systematically underestimated by coarse-resolution climate models.

Estimating Avian Mortality Due to Predation by Cats and Window Collisions in Sweden Using the Capture-Recapture Method

Using long-term bird ringing data and a capture-recapture approach, this study provides the first nationwide estimate for Sweden showing that while domestic cats and window collisions kill approximately 107,000 and 180,000 birds annually respectively, these anthropogenic threats pose a lower risk to overall bird populations compared to habitat degradation and other broader environmental pressures.

Building-scale functional mixing reveals a decarbonization window in cities

By developing a nationwide functional atlas of 200 million buildings in China, this study reveals that building-scale functional mixing follows a non-linear, three-stage relationship with carbon emissions, identifying a specific moderate mixing range that offers a critical decarbonization window for urban planning.

Effects of Land Cover Change and Climate Variability on the Hydrological Balance of the Kulpawn Basin, Ghana

This study utilizes Random Forest and SWAT modeling to demonstrate that the conversion of dense savannah forest to built-up areas and climate variability in Ghana's Kulpawn River Basin have significantly altered hydrological conditions, leading to decreased water yield and increased surface runoff, thereby necessitating sustainable land management and climate adaptation strategies.

EU fossil fuel supply-chain emissions: Options for regulation and implications

The paper projects that unregulated fossil fuel supply-chain emissions outside the EU will reach 380 Mt CO₂eq by 2030 and compares a methane standard versus a carbon price, finding both could achieve 80–90% abatement but noting that a standard risks compromising energy security if suppliers refuse compliance.

Spatio-temporal temperature variability, climate regime shifts and thermal risk in Bankura and Purulia districts of West Bengal, India

This study analyzes long-term temperature data from 1995 to 2025 in Bankura and Purulia districts, India, revealing a significant warming trend with a regime shift around 2007–2008, accelerated nighttime heating, and heightened thermal vulnerability in southern sectors, thereby providing a scientific foundation for regional climate adaptation.
