Firming weather dependent renewable generation yields single digit system level energy returns

This study demonstrates that while weather-dependent renewable sources like solar and wind show favorable installation-level energy returns, expanding the system boundary to include the necessary firming infrastructure (such as storage, overbuild, and backup) drastically reduces overall energy returns and increases carbon emissions, indicating that reliable decarbonization requires firm low-carbon generation with a sufficient net-energy surplus.

Population Migration, Household Carbon Emissions, and Governance Implications: An Ecological Network Analysis from 2000 to 2020

This study utilizes ecological network analysis to demonstrate that population migration from 2000 to 2020 drove a net increase in China's household carbon emissions, primarily through consumption expansion in eastern coastal urban agglomerations, thereby offering governance strategies to align population redistribution with carbon neutrality goals.

Newly Plastic Pollution in the Ocean

This study quantifies global plastic pollution in the Northern Hemisphere by revealing widespread monomer contamination in coastal sand and seawater, developing a new thermal decomposition method to trace pollution origins, and concluding that decades of plastic accumulation continue to release toxic monomers and contribute to global warming.

Crustal electrical structure of the eastern segment of the collision-related porphyry copper-polymetallic metallogenic belt in South Tibet and its constraints on fluid migration

By integrating a new 3-D electrical resistivity model with geochemical and geological data, this study reveals that the Qulong and Jiama porphyry copper deposits in South Tibet share a deep-seated magma chamber and fluid pathways, while also elucidating the lateral migration of hydrothermal fluids that facilitated the formation of associated molybdenum-dominated deposits.

Risk-service mismatches reveal conservation and restoration priorities in China’s major urban agglomerations

This study introduces a risk-service mismatch framework integrating ecological risk, ecosystem service values, and machine learning to identify distinct conservation and restoration priorities across China's three major urban agglomerations (Beijing-Tianjin-Hebei, Yangtze River Delta, and Guangdong-Hong Kong-Macao Greater Bay Area) from 2000 to 2020.

Cavitation–ozonation pretreatment boosts anaerobic biodegradability of mature landfill leachate

This study demonstrates that integrating hydrodynamic cavitation with ozonation as a pretreatment significantly enhances the biodegradability and biogas production of mature landfill leachate, achieving a 53.1% overall COD removal and favorable energy efficiency compared to untreated controls.

Causal Causality Between Climate Change and Apricot Yield: The Bootstrap Rolling Window Approach

This study utilizes a dynamic Bootstrap Rolling Window approach on data from Malatya, Türkiye (1991–2024) to reveal that while static models fail to detect a consistent causal link between climate variables and apricot yields, specific periods of climatic stress—such as drought and unseasonal warmth—significantly and negatively impact production, thereby arguing for dynamic rather than fixed agricultural risk management strategies.

Regional land status mapping using vegetation-water-drought spectral indices in the lower Ganges and Brahmaputra River basin

This study utilizes remote sensing and 14 spectral indices to analyze 20-year trends in the lower Ganges and Brahmaputra basin, revealing significant declines in surface water and forest cover alongside increases in built-up areas and drought frequency, thereby providing critical data for sustainable regional planning.
